and shall not be used in whole or in part without its written content

This print and information there in are proprietary to Bestar Electronics Industry Co., Ltd.

B

Samples for qualification testing require a minimum of 3 passes of standard reflow
solder profiles .2 hours of setting time is required between each reflow profile test.

4.2. Static Humidity:
Precondition at +25℃ for 1 hour.Then expose to +70℃ with 90 to 95% relative
humidity for 120 hours.Finally dry at room ambient for 3±1 hours before taking

final measurement.

4.3. Temperature Shock:
Each cycle shall consist of 15 minutes at -40℃,15 minutes at +85℃ with a 20
seconds maximum transition time .Test duration is for 30 cycle , starting from cold

to hot temperature.

4.4. ESD sensitivity:
Perform ESD sensitivity threshold measurements for each contact according to

MIL-STD-883E,Method 3015 for Human Body Model and for Machine Model.
Identify the ESD threshold levels indicating passage of 2000V Human Body
Model.

4.5. Random Vibrations:
Vibrate randomly from 20 Hz to 2000Hz using the Following Power Spectra

Density(PSD) profile: It is a +3dB/octave .Starting with 0.01325g2/ Hz from 20Hz

to 80Hz ,then 0.053g2/ Hz or 8g's RMS level from 80Hz to the PSD tolerance is ±
3dB from 20Hz to 1000Hz and ±6dB above 1000Hz .The analyzer bandwidth to
be set at 25Hz BW from 20Hz to 2000Hz , 50Hz BW to 1000Hz,and finally 100Hz
BW to 2000Hz ,The test time is 15 minutes per plane.

4.6. Mechanical Shock:
Subject samples to half sine shock pulses(3000 g's±15% for 0.3ms )in each

direction ,totally 6 shocks.

4.7.Operation Life:
Subject samples to +85 for 168 hours under full rated power.℃

4.8. Solder Reflow:
One pass through standard solder reflow profile.

4.9.Drop Test:

Samples are fixed inside the fixture and droped naturally from the 2m height onto
a concrete plane in six direction for three times ,total 18 times .The dimension of
test fixture is 102（L）*54(W)*41(H)mm, and the weight is around 200g.

4.10.Sinusoidal Vibration:

Vibrate randomly from 10Hz to 2000Hz ,1 octave/minute with 2mm amplitude
(peak to peak) for 2 hours in each direction.

4.11.PC Board Solder Adhesion :
Each test PC board shall contain only one part .Place PC Board for testing upside
down on two supports spaced 90mm apart centering the part to within ±1mm of
the span .Orient this part such that the longest dimension is perpendicula between
the two supports. Next using a force gauge ,also centering to within ±1mm of the

G

span's center ,slowly apply a downward vertical force and push with increasing

G

force until the part's terminations separate from the PC board. Record at which
deflection point mechanical failure occurs. Parts shall withstand a minimum
deflection as described below .Repeat for each test sample. Identify precisely
where termination stress failure(s) occur and include at least one picture .

6.1 The products mustn't be washed

6.2 Storage Condition
The products should be stored in the room ,where the temperature/humidity is stable. And avoid such

places where there are large temperature changes. Please store the products at the foll-

owing conditions:
Temperature: -10 to + 40 C Humidity: 15 to 85% R.H.

6.3 Expire Date on Storage

Expire date (Shelf life) of the products is six months after deliveried under the conditions of a

sealed and an unopened package. Please use the products within six months after deliveried.
If you store the products for a long time (more than six months), use carefully because the
products may be degraded in the solderability and/or rusty.Please confirm solderability and
characteristics for the products regularly.

6.4 Notice on Product Storage
(1) Please do not store the products in a chemical atmosphere (Acids, Alkali, Bases, Organic
gas, Sulfides and so on), because the characteristics may be reduced at quality, and/or be d­egraded in the solderability due to the storage in a chemical atmosphere.
(2) Please use the products immediately after the package is opened, because the character-

istics may be reduced at quality, and/or be degraded in the solderability due to storage under

the poor condition.
