GENERAL DESCRIPTION
The TEA1069 and TEA1069A contain all the functions
needed to build a highly featured, high-performance fully
electronic telephone set.
The device incorporates a speech/transmission part, a
dialler part and a ringer part. By offering a wide range of
possible adaptations for each part, the TEA1069 and
TEA1069A application can be easily adapted to meet
different requirements.
The TEA1069A offers some different timings and diode
options compared to the TEA1069.
Where pin numbers are mentioned in this data sheet we
refer to the TEA1069N, unless otherwise indicated.
Speech part
The speech/transmission part performs all speech and line
interface functions required in electronic sets. It operates
at line voltages down to 1.6 V DC to facilitate the use of
more telephones connected in parallel.
Dialler part
The dialler part offers a 32-digit Last Number Redial (LNR)
and 13 memories. Hands-free control is included allowing
the TEA1069 and TEA1069A to be used not only in basic
telephones, but also in feature phones offering hands-free
dialling via the TEA1083 call-progress monitor IC and/or
full hands-free operation via the TEA1093 hands-free IC.
The hold function allows the user to suspend the
conversation and resume the call either on the same
phone or on a parallel phone. Additionally through the
music-on-hold function a melody is transmitted while the
set is put on hold. The keytones provide in a buzzer an
audible feedback of a valid key pressed.

FUNCTIONAL DESCRIPTION
Speech part
For numbering of components refer to Figs 28 and 29.
SUPPLIES VCC, LN, SLPE, REG AND STAB
Power for the IC and its peripheral circuits is usually
obtained from the telephone line (see Fig.4).
The circuit creates a stabilized voltage (V
= 3.7 V)
ref
between LN and SLPE. This reference voltage is
temperature compensated and can be adjusted by means
of an external resistor RVA. It can be increased by
connecting an RVA resistor (R60) between REG and SLPE
or decreased by connecting an RVA resistor (R61)
between REG and LN. This internal voltage reference is
decoupled by capacitor C3 between REG and VEE.

This decoupling capacitor realises the set impedance
conversion from its DC value to its AC value in the audio
frequency range.
The internal transmission part of the circuitry (including the
earpiece amplifier) is supplied from V
. This voltage
CC
supply is derived from the LN voltage via a dropping
resistor (R1) and must be decoupled by a capacitor (C1)
between VCC and VEE. This supply point may also be used
to supply the dialler/ringer (VDD) part or external circuit e.g.
electret microphone.
The DC current flowing into the set is determined by the
exchange supply voltage V
resistance R
line R
. When the line current (I

and the DC resistance of the telephone

, the feeding bridge

) is more than 0.5 mA
line
greater than the sum of the IC supply current (ICC) and the
current drawn by the peripheral circuitry connected to V
(Ip), the excess current is shunted to SLPE via LN.

The circuit has an internal current stabilizer operating at a
level determined by resistor R5 connected between STAB
and V
EE
.
In normal use the value of R5 would be 3.6 kΩ and the
value of R9 would be 20 Ω.
Changing the value of R5 or R9 will affect microphone
gain, DTMF gain, gain control characteristics, sidetone
level, maximum output swing on LN and the DC
characteristics (especially at low line current).
At line currents below 9 mA the internal reference voltage
is automatically adjusted to a lower value (typically 1.6 V
at 1 mA). This means that more sets can be operated in
parallel with DC line voltages (excluding the polarity guard)
down to an absolute minimum voltage of 1.6 V. At line
currents below 9 mA the circuit has limited sending and
receiving levels.
Under normal conditions, when I

ref
In the audio frequency range the dynamic impedance is
largely determined by R1. Figure 5 shows the equivalent
impedance of the circuit.
Current (Ip) available from VCC for the dialler part and
peripheral circuits depends on the external components
used. Figure 6 shows this current for VCC> 2.2 V. When
MUTE is HIGH i.e. when the receiving amplifier (supplied
from VCC) is driven, the available current is further
reduced. Current availability can be increased by
connecting the supply IC TEA1081 in parallel with R1, or
by increasing the DC line voltage by means of an external
resistor (RVA= R60) connected between REG and SLPE.

MICROPHONE INPUTS MIC+ AND MIC− AND GAIN PINS GAS1 AND GAS2
The circuit has symmetrical microphone inputs. Its input impedance is 64 kΩ (2 × 32 kΩ) and its voltage gain is typically
52 dB (when R7 = 68 kΩ). Dynamic, magnetic, piezoelectric or electret (with built-in FET source followers) microphones
can be used. Microphone arrangements are illustrated in Fig.7.

Fig.7 Alternative microphone arrangements.
The gain of the microphone amplifier can be adjusted
between 44 dB and 52 dB to suit the sensitivity of the
transducer in use. The gain is proportional to the value of
R7 which is connected between GAS1 and GAS2. Stability
is ensured by two external capacitors, C6 connected
between GAS1 and SLPE and C17 connected between
GAS1 and VEE. The value of C6 is 100 pF but this may be
increased to obtain a first-order low-pass filter. The value
of C17 is 10 times the value of C6. The cut-off frequency
corresponds to the time constant R7 × C6.
ECEIVING AMPLIFIER IR, QR AND GAR
R
The receiving amplifier has one input (IR) and one output
(QR). Earpiece arrangements are illustrated in Fig.8.
The IR to QR gain is typically 31 dB (when R4 = 100 kΩ).
It can be adjusted between 20 and 31 dB to match the
sensitivity of the transducer in use.
The gain is set with the value of R4 which is connected
between GAR and QR. The overall receive gain, between
LN and QR, is calculated by subtracting the anti-sidetone
network attenuation (32 dB) from the amplifier gain.
Two external capacitors, C4 and C7, ensure stability. C4 is
normally 100 pF and C7 is 10 times the value of C4.
The value of C4 may be increased to obtain a first-order
low-pass filter. The cut-off frequency will depend on the
time constant R4 × C4.
The output voltage of the receiving amplifier is specified for
continuous-wave drive. The maximum output voltage will
be higher under speech conditions where the peak to RMS
ratio is higher.

DUAL TONE MULTI-FREQUENCY INPUT DTMF
When the DTMF input is enabled (MUTE is LOW) dialling
tones may be sent on to the line. The voltage gain from
DTMF to LN is typically 25.5 dB (when R7 = 68 kΩ) and
varies with R7 in the same way as the microphone gain.
The tones can be heard in the earpiece at a low level

The control range is 5.8 dB which corresponds to a line
length of 5 km for a 0.5 mm diameter twisted-pair copper
cable with a DC resistance of 176 Ω/km and average
attenuation of 1.2 dB/km. Resistor R6 should be chosen in
accordance with the exchange supply voltage and its
feeding bridge resistance (see Fig.9 and Table 1).

UTOMATIC GAIN CONTROL INPUT AGC
Automatic line loss compensation is achieved by
connecting a resistor (R6) between AGC and VEE.
The automatic gain control varies the gain of the
The ratio of start and stop currents of the AGC curve is
independent of the value of R6. If no automatic line-loss
compensation is required the AGC pin may be left
open-circuit. The amplifiers, in this condition, will give their
maximum specified gain.

The power supply must be maintained for data storage.
The RAM retention voltage (standby supply voltage) may
drop down to 1.0 V. Applying a large capacitor across the
supply terminals can retain the memory if power
connections are broken. The minimum operation voltage is
2.5 V. The internal power-on reset is enabled for a voltage
below this minimum operation voltage.

SCILLATOR INPUT/OUTPUT: PINS XTAL1AND XTAL2
Time base for the TEA1069 and TEA1069A is a
crystal-controlled on-chip oscillator which is completed by
connecting a 3.579545 MHz crystal or ceramic resonator
between XTAL1 and XTAL2. The oscillator starts when
VDD reaches the operation voltage level and
CE/FDI = HIGH. The following types of ceramic
resonators are recommended:
• Kyocera PBRC3.58ARPC10 (wired)
• Kyocera KBR3.58MSATRPC10 (SMD)
• Murata CSA3.58MG310VA (wired).
R
ESET INPUT: PIN RESET
Pin RESET is an input to the internal reset circuit. When
RESET = HIGH, it can be used to initialize the TEA1069
and TEA1069A which is normally done by the CE/FDI
input. The on-chip power-on reset generates a reset pulse
if VDD drops below 2.5 V. In this event a proper start-up

occurs after the supply voltage rises above the minimum
operation voltage level again.
During and directly after reset pins 14 to 19, 21, 29 to 32,
34 and 35 are set HIGH; pins 8, 20, 22, 26 to 28 and 33
are set to LOW.
The RESET pin can be connected to V
resistor of 100 kΩ to 1 MΩ, which will save leakage
current. A capacitor connected to VDD can be used to
extend the reset time, in case a longer reset is desirable.
To prevent the dialler from reacting on voltage
disturbances on the telephone line a time-out is active.
The dialler returns to standby state if the voltage on the line
has disappeared for more than this reset-delay time (trd).
C
HIP ENABLE/FREQUENCY DISCRIMINATOR INPUT:
PIN CE/FDI
This active HIGH input is used to initialize part of the
system, to select the on-line, standby, or ringer mode and
to detect line power breaks. To keep the TEA1069 and
TEA1069A in the on-line mode, CE/FDI has to be HIGH.
In the exchange, several AC signals can be superimposed
on the DC signal, e.g. dialling tone, busy tone,
disturbances (like line power breaks), and the ringer
signal. The ringer signal is evaluated, and checked if its
frequency is within the limits of the frequency interval as
set by the diode option RFS. It is assumed that the ringer
frequency at pin CE/FDI is the double of the frequency
present on the telephone line.

In case of a valid ringer signal the user is alerted through
a melody at the TONE output, generated by the ringer part
of the TEA1069 and TEA1069A. This melody follows the
cadence of the ringer signal. Both the melody and the
volume can be selected. The melody frequency and
duration are given in Table 2.
To distinguish among different operating states after
CE/FDI is activated, input CSI is used. The basic states

ULSE DIALLER: PINS DP/FL, MOH/DMO AND MUTE
The pulse dialling system uses line current interruptions to
signal the digits dialled to the exchange. The number of
line current interruptions corresponds with the digit dialled
except for the digit [0] which is characterized by
10 interruptions. Before each digit there is an inter-digit
pause.
Valid keys are the digits [0] to [9] and [PAUSE].
The pulse dialling mode, the make/break ratio and the
access pause time depend on the diode options: PTS,
M/B, APT and APT2. DP/FL is LOW when VDD is below
power-on reset trip level and when RESET is HIGH.
The MOH/DMO pin (diode GOS = on) is used to reduce
the voltage swing over the a/b terminals during pulse
dialling. Several countries require this feature. The MUTE
pin is an open drain output which requires a pull-up
resistor.MUTE is HIGH when VDD is below power-on reset
trip level and when RESET is HIGH.

when keys [3], [RECALL] and [4] are pressed.

KEYBOARD: PINS ROW1 TO ROW5 AND COL1 TO COL6
The sense columns inputs and scanning rows outputs are
directly connected to a single contact keyboard matrix.
A second key entry will be valid after having released the
first button and after having pressed the second button.
Simultaneously pressing 2 buttons will disable the first
entered key. A key entry becomes valid when the
debounce time td has elapsed.
The column and row pins (except ROW5) are HIGH when
V
is below power-on reset trip level and when RESET is
DD
HIGH.
ROW5 is an open-drain input/output; this configuration is
used to avoid current flowing in the on-line or standby
state. A pull-up resistor should be connected to ROW5.
ROW5 is LOW when VDD is below power-on reset trip level
and when RESET is HIGH.

KEY TONE: PIN KT/EARTH
Every time a valid key is pressed a keytone is generated
with a frequency of 606 Hz and a duration of 30 ms. This
function is selected by the diode GOS = off. KT/EARTH is
LOW when VDD is below power-on reset trip level and
when RESET is HIGH.
V
OLUME CONTROL: PINS VOL1 AND VOL2
Both pins can control the volume of the ringer and/or the
hands-free circuit. The state of VOL1/VOL2 is controlled
by a state machine as depicted in Fig.24.
VOL1 and VOL2 are push-pull outputs. Both are set LOW
when VDD is below power-on reset trip level and when
RESET is HIGH.
USIC-ON-HOLD: PIN MOH/DMO
M
When the dialler is in the hold state (see Fig.23) a melody
is generated via pin TONE. In this state pin MOH/DMO can
be used via diode GOS = off as an enable signal for the
hardware to indicate that the tone should be switched to
the telephone line.
MOH/DMO is a push-pull output. It is set LOW when V
is below power-on reset trip level and when RESET is
HIGH.
DD
TEA1069; TEA1069A
HANDS-FREE: PIN HF
During the on-line state, the hands-free output pin HF is
used for enabling the hands-free hardware. The pin will
change state depending on specific key-sequences
(see Fig.23).
HF is a push-pull output. It is set LOW when VDD is below
power-on reset trip level and when RESET is HIGH.
MODE: PIN HOLD
HOLD
One way to terminate the hold state (see Fig.23) is a
change in state of the signal at pin HOLD. This input
should reflect the line current. If current is flowing the
signal at pin HOLD should be HIGH, if not it should be
LOW.
This pin is not debounced. The signal applied should be
filtered by the hardware. HOLD is HIGH when VDD is below
power-on reset trip level and when RESET is HIGH.
Key sequences
The behaviour of the TEA1069 and TEA1069A can be
modelled as a State Transition Diagram (STD) shown in
Fig.21.

The STD contains the states (rectangles in the figure) and
state transitions (arrows) of the set. The upper arrow in the
figure pointing to the standby state means that the set is
initially in the standby state. When for instance an
incoming call is detected, the set enters the ringer state,
waiting for a reaction of the user. If the user answers the
call on a handset, the set enters the on-line state.
The TEA1069 and TEA1069A have 3 basic states:
• Standby state
• Ringer state
• On-line state.
Each state with its own functional requirements is
described in the following sections.
S
TANDBY STATE
In standby state the TEA1069 and TEA1069A are inactive.
The current drawn is for memory retention and depends on
the loads of the inputs/outputs of the dialler. In this state
output DP/FL is HIGH so that the line is disconnected.
TEA1069; TEA1069A
RINGER STATE
If the set is in standby mode, a ringer signal can be
received from the line. After evaluating the incoming ringer
signal (and ringer signal is valid), the TEA1069 and
TEA1069A start a melody via the TONE output ringer
hardware, and stops this melody if the ringer signal is not
valid any more. After going off-hook, the ringer signal stops
and the set is in conversation (on-line) state.
During a ringer burst the ringer volume can be changed
according to Fig.24 and melodies can be changed
according to Table 7.

The ICs leave the standby state if:
• The set goes off-hook (lift handset or press [HOOK])
• A ringer-signal is available on the line.
The ICs go to the standby state if:
• The set goes on-hook
(handset on the cradle or press [HOOK])
• A line-break occurs for at least the reset delay time (trd)
• The ringer-signal becomes invalid.
ON-LINE STATE
In this paragraph all the actions of the TEA1069 and
TEA1069A during on-line state are described. The on-line
mode starts with making output DP/FL LOW, which makes
line current flow possible. The on-line state contains a
number of sub-states (see Fig.22):
• Conversation state
• Dialling state
• Memory recall state
• Program state.

• Handset state.
The conversation states are shown in Fig.23.
• Hands-free state.
In hands-free mode output HF becomes HIGH which
activates a TEA1093/1094 hands-free IC. This state can
be reached from standby state and from the handset
state as follows:
– the [HOOK] key is pressed during standby mode
– the [HOOK] key is pressed during handset state is
lifted, then when the handset is put on the cradle the
set stays in the hands-free mode.
The set leaves the hands-free mode and output HF
becomes LOW when:
– the [HOOK] key is pressed and the handset is on the
cradle, the set goes to the standby mode
– the [HOOK] key is pressed and the handset is lifted,
the set goes to the handset state.
The volume on the loudspeaker or buzzer, in hands-free
and ringer mode, can be controlled in four levels using
the [VOL+] and [VOL−] keys.
MBH211
The hands-free volume can be changed according to
Fig.24.
• Hold state.
The hold state is entered when the [HOLD/MUTE] key is
pressed (diode HMS = on). This state can be entered
either from handset state or from hands-free state. Upon
entering this state outputs HF and MUTE become LOW.
In hold state a music-on-hold melody is generated by
output TONE. Pin MOH/DMO is HIGH (diode
GOS = off) during this state. This signal can be used to
adjust the volume of the TONE pin. SinceMUTE is LOW
the TONE output is transmitted to the telephone line.
As long as the TEA1069 and TEA1069A are in this state
the HOLD input pin is tested.
The set leaves the hold state when:
– [HOLD/MUTE] is pressed, the set returns to either the
handset or hands-free state
– the HOLD input becomes LOW, now the TEA1069
and TEA1069A return to the standby state.

• Mute state.
When the [HOLD/MUTE] key is pressed (HMS = off) the
mute state is entered and MUTE becomes LOW.
In mute state a music-on-hold melody is generated by
output TONE. Pin MOH/DMO is HIGH (diode
GOS = off) during this state.
This signal can be used to adjust the volume of the
TONE pin. Since MUTE is LOW the TONE output is
transmitted to the telephone line. The mute state is left
when:
– [HOLD/MUTE] is pressed, set returns to either
handset- or hands-free state
– a dial action is started.

However when keying-in is much faster then dialling-out,
then the 32 digit dialling register will overflow. When this
occurs the dialling is stopped and the error beep will be
generated.
There are two dial modes: pulse dialling and tone dialling.
The initial dialling mode is determined by option PTS.
The state machine which controls the dial mode is shown
in Fig.25.
During the dial-keys entries the TEA1069 and TEA1069A
start immediately with transmission of the digit(s); the
minimum transmission time is unaffected by the speed of
the entry. Transmission continues as long as further
dial-keys entries have to be processed.
Fig.25 Dialling mode state machine.
• Pulse dialling.
In this mode all valid keys are dialled by the pulse dialler.
When during pulse dialling key [∗/T] is pressed, the
TEA1069 and TEA1069A switch over to tone dialling
(mixed mode dialling). After the switch-over, valid keys
are dialled by the tone dialler. The temporary tone mode
is terminated by going on-hook or recall.
• Tone dialling.
The ICs convert valid keys into data for the on-chip
DTMF generator. Tones are transmitted via output
TONE with minimum tone burst/pause duration.
The maximum tone burst/pause duration is equal to the
key pressing/release time.
• Register recall (flash/earth).
The [RECALL] key will result in a flash or earth action.
• Access pause.
When the [PAUSE/LNR] button is not the first key
pressed, an access pause is entered for repertory or
redialling procedures. When an access pause is
executed MUTE is HIGH. During manual dialling no
access pauses are dialled.
• Last Number Redial (LNR).
If the first key pressed is the [PAUSE/LNR] button, the
number stored in the redial register is recalled and
transmitted. A maximum number of 32 digits can be
1998 Jan 0826
Page 27
Philips SemiconductorsProduct specification
Versatile speech/dialler/ringer with
music-on-hold
accepted for last number redial. If this maximum is
reached the redial function is inhibited. During LNR
programmed access pauses are also dialled.
The [RECALL] key and the (in pulse dialling mode
allowed) tone switch key [∗/T] are also stored in LNR
memory.
• Notepad function.
In conversation state it is possible to store a number into
the LNR register, which may be dialled after an
on-hook/off-hook action. The procedure is as follows:
– press [STORE]
– press to-be-stored sequence of the digits [0] to [9],
[PAUSE/LNR], [∗/T] or [RECALL]
– press [STORE]
– press [PAUSE/LNR].
Memory recall state
Repertory numbers can be dialled-out after or before
entering manual dialling, last number redial and by
entering the memory locations in successive order.
The stored numbers can be dialled by the following
procedures:
• Press [MRC]
• Press one of the numeric keys [0] to [9], corresponding
to the memory location
or
• Press one of the direct memory keys ([M1] to [M10]).
Program state
The program mode can be entered from the conversation
(on-line) mode.
Pressing the [STORE] key in this state puts the TEA1069
and TEA1069A in the program mode. The program state
can be left by going on-hook (by putting the handset on the
cradle or pressing the [HOOK] key), the program mode is
interrupted and nothing is stored, or by ending the store
procedures resulting in a proper store of the programmed
item.
• Programming repertory numbers.
Storing of a new repertory number including access
pauses, tone switch and register recall can be done by
the following procedures:
– press [STORE]
– press to-be-stored sequence of the digits [0] to [9],
[PAUSE/LNR], [∗/T] or [RECALL]
– press [MRC]
TEA1069; TEA1069A
– press one of the numeric keys [0] to [9],
corresponding to the memory location
or
– press [STORE]
– press to-be-stored sequence of the digits [0] to [9],
[PAUSE/LNR], [∗/T] or [RECALL]
– press [M1] to [M10].
For storing the redial number in repertory use:
– press [STORE]
– press [PAUSE/LNR]
– press [MRC]
– press one of the numeric keys [0] to [9],
corresponding to the memory location
or
– press [STORE]
– press [PAUSE/LNR]
– press [M1] to [M10].
If the keyboard described in Fig.17 is selected by the
KBS diode option, repertory memory place
[M1] = [MRC] + [1] to [M10] = [MRC] + [0], thus the set
has 10 repertory numbers which can be selected via two
different ways.
If the keyboard described in Fig.19 is selected by the
KBS diode option repertory memory place
[MRC] + [0] to [MRC] + [9] and [M1], [M2] and [M3] are
different repertory numbers, thus this set has in total
13 repertory numbers.
• Memory overflow.
A maximum of 224 digits can be stored in the repertory
memories. When the maximum is reached, no keytone
is generated when trying to store more digits. The store
procedure is cancelled automatically.
• Clear repertory number.
Clearing a memory location is possible via the same
procedure as for storing a number, except no telephone
number is entered, thus one of the following sequences
must be used:
– press [STORE]
– press [MRC]
– press one of the numeric keys [0] to [9],
corresponding to the memory location
or
– press [STORE]
– press [M1] to [M10].

SOLDERING
Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
“IC Package Databook”
our
SDIP
SOLDERING BY DIPPING OR BY WA VE
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
R
EPAIRING SOLDERED JOINTS
Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.
QFP
REFLOW SOLDERING
Reflow soldering techniques are suitable for all QFP
packages.
The choice of heating method may be influenced by larger
plastic QFP packages (44 leads, or more). If infrared or
vapour phase heating is used and the large packages are
not absolutely dry (less than 0.1% moisture content by
weight), vaporization of the small amount of moisture in
them can cause cracking of the plastic body. For more
information, refer to the Drypack chapter in our
Reference Handbook”
(order code 9398 652 90011).

(order code 9397 750 00192).
TEA1069; TEA1069A
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
Several methods exist for reflowing; for example,
infrared/convection heating in a conveyor type oven.
Throughput times (preheating, soldering and cooling) vary
between 50 and 300 seconds depending on heating
method. Typical reflow peak temperatures range from
215 to 250 °C.
AVE SOLDERING
W
Wave soldering is not recommended for QFP packages.
This is because of the likelihood of solder bridging due to
closely-spaced leads and the possibility of incomplete
solder penetration in multi-lead devices.
CAUTION
Wave soldering is NOT applicable for all QFP
packages with a pitch (e) equal or less than 0.5 mm.
If wave soldering cannot be avoided, for QFP
packages with a pitch (e) larger than 0.5 mm, the
following conditions must be observed:
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave)
soldering technique should be used.
• The footprint must be at an angle of 45° to the board
direction and must incorporate solder thieves
downstream and at the side corners.
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured. Maximum permissible solder
temperature is 260 °C, and maximum duration of package
immersion in solder is 10 seconds, if cooled to less than
150 °C within 6 seconds. Typical dwell time is 4 seconds
at 250 °C. A mildly-activated flux will eliminate the need for
removal of corrosive residues in most applications.
R
EPAIRING SOLDERED JOINTS
Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
