Reliability test

High temperature storage test

Leave the specimen in atmosphere of 100℃ ±2℃ for 1000h ±12h.

Low temperature storage test

Leave the specimen in atmosphere of -40℃ ±3℃ for 1000h ±12h.

High humidity storage test

Leave the specimen in atmosphere of 40℃ ±2℃ and 90%RH to 95%RH for 1000h ±12h.

Thermal shock test

Perform 100 cycles with -30℃ ±3℃(15min)≈85℃±2℃(15min) as one cycle.

2-5 Resistance to soldering heat

Immerse 3mm ±0.5mm from termination to 250℃±5℃ melted solder for 2 seconds.

After the test in above items 2-1 to 2-5, the rate of variation for resistance(R25) shall be within±3% to the initial value, and B-value shall be within ±2% to the initial value.

Measure range:-40℃~250℃( Normal)
