TEST METHOD
Place the specimen in the test chamber and subject to 42 damp heat cycles. Each
one of which consists of the steps 1 to 7 as figure 9. The total length of test is 1,000
hours. Have the specimen stabilized at room temperature for 24 hours after testing.
Measure the resistance to determine ΔR/R(%).
ACCEPTANCE STANDARD
±(2.0%+0.05)
No visible damage
Life Place the specimen in the oven at 70±2°C. Apply the rated voltage to the specimen ±(2%+0.1)
at the 1.5 hours on and 0.5 hour off cycle. The total length of test is 1,000 hours.
Have the specimen stabilized at room temperature for one hour minimum after
No visible damage
testing.
Measure the ΔR/R(%).
Solderability Immerse the specimen in the solder pot at 235±5°C for 5 sec.
At least 95% solder coverage on
the termination
Bending
Strength
Mount the specimen on a test board as
shown in the figure 8. Slowly apply the force
till the board is bent for 5±1 sec.
Measure the ΔR/R(%) at this position.
