Pb (Lead) Free Solder
When soldering, be sure to use the Pb free solder.
Information about lead-free soldering
Philips CE is producing lead-free sets from 1.1.2005
onwards.
IDENTIFICATION
Regardless of special logo (not always
indicated)
One must treat all sets from
onwards, according to the next rule:
Serial Number gives a 9-digit. Digit 2&3 shows the
WEEK, and digit 4 shows the YEAR.
So from onwards=from 1 Jan 2005 onwards
Important note: In fact also products of year 2004
must be treated in this way as long as you avoid
mixing solder-alloys (leaded/ lead- free) . So bes t to
always use SAC305 and the higher temperatures
belong to this.
Due to lead-free technology some rules have to be
respected by the workshop during a repair:
• Use only lead-free solder alloy Philips SAC305 with
order code 0622 149 00106. If lead-free solderpaste is required, please contact the manufacturer
of your solder-equipment. In general use of solderpaste within workshops should be avoided because
paste is not easy to store and to handle.
• Use only adequate solder tools applicable for leadfree solder alloy. The solder tool must be able
• To reach at least a solder-temperature of 400°C,
• To stabilize the adjusted temperature at the solder-
• To exchange solder-tips for different applications.
• Adjust your solder tool so that a temperature around
360°C
solder joint. Heating-time of the solder-joint should
not exceed ~ 4 sec. Avoid temperatures above
400°C otherwise wear-out of tips will rise drastically
and flux-fluid will be destroyed. To avoid wear-out of
tips switch off un-used equipment, or reduce heat.
• Mix of lead-free solder alloy / parts with leaded
solder alloy / parts is possible but PHILIPS
recommends strongly to avoid mixed solder alloy
types (leaded and lead-free).
If one cannot avoid or does not know whether
product is lead-free, clean carefully the solder-joint
from old solder alloy and re-solder with new solder
alloy (SAC305).
• Use only original spare-parts listed in the ServiceManuals. Not listed standard-material (commodities)
has to be purchased at external companies.
015
tip
- 380°C is reached and stabilized at the
1 Jan 2005
1-1-1 HK100_SN
• Special information for BGA-ICs:
- always use the 12nc-recognizable soldering
temperature profile of the specific BGA (for desoldering always use the lead-free temperature
profile, in case of doubt)
- lead free BGA-ICs will be delivered in so-called
'dry-packaging' (sealed pack including a silica gel
pack) to protect the IC against moisture. After
opening, dependent of MSL-level seen on indicatorlabel in the bag, the BGA-IC possibly still has to be
baked dry. (MSL=Moisture Sensitivity Level). This
will be communicated via AYS-website.
Do not re-use BGAs at all.
• For sets produced before 1.1.2005 (except products
of 2004), containing leaded solder-alloy and
components, all needed spare-parts will be available
till the end of the service-period. For repair of such
sets nothing changes.
• On our website
www.atyourservice.ce.Philips.com
information to:
• BGA-de-/soldering (+ baking instructions)
• Heating-profiles of BGAs and other ICs used in
Philips-sets
You will find this and more technical information within
the “magazine”, chapter “workshop news”.

How to Remove / Install Flat Pack-IC
1. Removal
With Hot-Air Flat Pack-IC Desoldering Machine:
1. Prepare the hot-air flat pack-IC desoldering
machine, then apply hot air to the Flat Pack-IC
(about 5 to 6 seconds). (Fig. S-1-1)
Fig. S-1-1
2. Remove the flat pack-IC with tweezers while
applying the hot air.
3. Bottom of the flat pack-IC is fixed with glue to the
CBA; when removing entire flat pack-IC, first apply
soldering iron to center of the flat pack-IC and heat
up. Then remove (glue will be melted). (Fig. S-1-6)
4. Release the flat pack-IC from the CBA using
tweezers. (Fig. S-1-6)
CAUTION:
1. The Flat Pack-IC shape may differ by models. Use
an appropriate hot-air flat pack-IC desoldering
machine, whose shape matches that of the Flat
Pack-IC.
2. Do not supply hot air to the chip parts around the
flat pack-IC for over 6 seconds because damage
to the chip parts may occur. Put masking tape
around the flat pack-IC to protect other parts from
damage. (Fig. S-1-2)
1-1-2 HK100_SN
3. The flat pack-IC on the CBA is affixed with glue, so
be careful not to break or damage the foil of each
pin or the solder lands under the IC when
removing it.

With Soldering Iron:
1. Using desoldering braid, remove the solder from
all pins of the flat pack-IC. When you use solder
flux which is applied to all pins of the flat pack-IC,
you can remove it easily. (Fig. S-1-3)
With Iron Wire:
1. Using desoldering braid, remove the solder from
all pins of the flat pack-IC. When you use solder
flux which is applied to all pins of the flat pack-IC,
you can remove it easily. (Fig. S-1-3)
2. Affix the wire to a workbench or solid mounting
point, as shown in Fig. S-1-5.
3. While heating the pins using a fine tip soldering
iron or hot air blower, pull up the wire as the solder
melts so as to lift the IC leads from the CBA
contact pads as shown in Fig. S-1-5.
4. Bottom of the flat pack-IC is fixed with glue to the
CBA; when removing entire flat pack-IC, first apply
soldering iron to center of the flat pack-IC and heat
up. Then remove (glue will be melted). (Fig. S-1-6)
5. Release the flat pack-IC from the CBA using
tweezers. (Fig. S-1-6)
Note: When using a soldering iron, care must be
taken to ensure that the flat pack-IC is not
being held by glue. When the flat pack-IC is
removed from the CBA, handle it gently
because it may be damaged if force is applied.

2. Lift each lead of the flat pack-IC upward one by
one, using a sharp pin or wire to which solder will
not adhere (iron wire). When heating the pins, use
a fine tip soldering iron or a hot air desoldering
machine. (Fig. S-1-4)

1-1-3 HK100_SN
2. Installation
1. Using desoldering braid, remove the solder from
the foil of each pin of the flat pack-IC on the CBA
so you can install a replacement flat pack-IC more
easily.
2. The “●” mark on the flat pack-IC indicates pin 1.
(See Fig. S-1-7.) Be sure this mark matches the 1
on the PCB when positioning for installation. Then
presolder the four corners of the flat pack-IC. (See
Fig. S-1-8.)
3. Solder all pins of the flat pack-IC. Be sure that
none of the pins have solder bridges.
Example :
Pin 1 of the Flat Pack-IC
is indicated by a " " mark.

Instructions for Handling Semiconductors
Electrostatic breakdown of the semi-cond uc tors may
occur due to a potential difference caused by
electrostatic charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1 MΩ) that is
properly grounded to remove any static electricity that
may be charged on the body.
2. Ground for Workbench
Be sure to place a conductive sheet or copper plate
with proper grounding (1 MΩ) on the workbench or
other surface, where the semi-conductors are to be
placed. Because the static electricity charge on
clothing will not escape through the body grounding
band, be careful to avoid contacting semi-conductors
with your clothing.

WARNING
Many electrical and mechanical parts in this chassis
have special characteristics. These characteristics
often pass unnoticed and the protection afforded by
them cannot necessarily be obtained by using
replacement components rated for higher voltage,
wattage, etc. Replacement parts that have these special safety character istics are id entified in th is manual
and its supplements; electrical components having
such features are identified by the mark " ! " in the
schematic diagram and the par ts list. Before replacing
any of these components, read the parts list in this
manual carefully. The use of substitute replacement
parts that do not have the same safety characterist ics
as specified in the pa r ts list may create sh ock, fire, or
other hazards.

Notes:
1. Do not use the part number shown on th ese drawings for ordering. The correct part number is
shown in the parts list, and may be slightly different
or amended since these drawings were prepared.
2. To maintain original function and reliability of
repaired units, use only orig inal replacement par ts
which are listed with their part numbers in the parts
list section of the service manual.
3. How to read converged lines.
