MECHANICAL
NO. ITEMS
More than 90% of the
1 Solderability test
2 lead tensile 1.0 Kg MIN. The lead of product is pulled with a load of
strength test 1.0kg mininum until lead breakdown. The tensile
termnial electrode
should be covered
with solder.
Dipping: 245 ± 5 ℃, 3 ± 1 seconds
force shall be recorded.
CONDITIONSSPECIFICATIONS
3 Vibration test
4 Soldering heat Visual:OK The leads of product are dipped into a solder pot
resistance test Circuit:OK
△L/L≦±7%
Visual:OK
The product is fixed ento the vibration with
amplitude of 1.52m/m at a frequency of 10~55Hz
sweeping for lmin. The vibration is done at X,Y,
Z direction respectively for 2 houes, totally 6
hours.

SPECIFICATIONS
△L/L≦±5% The product is placed in a chamber of 40±2℃,
90~95%RH for 96 hours. Measurement is done
after the reaovery of 4~24 hours.
△L/L≦±5% The product is placed in a chamber of 80±2℃,
of 4~24 hours.

MAG.LAYERS
△L/L≦±5% The product is placed in a chamber of -40±2℃,
for 96 hours. Measurement is done after
recovery of 4~24 hours.
△L/L≦±5%
The specimens are placed in a chamber and the
temp is then lowered to -20±2℃ for one hour.
The temp will raised to +80±2℃ for one hour.
This constitues one cycle. Ten cycles of such
testing shall be completed. Measurement is made
after recovery for 4~24 hours from the
completion of testing.
