MECHANICAL CHARACTERISTICS
item solderability soldering heat resistance test condition Lead terminals are immersed in solder bath of 270 5C for 3 1 seconds. The product should follow the reflow temperature curve to test its reflow thermo stability. For 10 seconds, the force of 9.8N (1.0kg) is applied to each terminal in axial direction. The buzzer will be measured after applying a vibration amplitude of 1.5 mm with 10 to 55 Hz band of vibration frequency to each of the 3 perpendicular directions for 2 hours. The part will be dropped from a height of 75 cm onto a 40 mm thick wooden board 3 times in 3 axes (X, Y, Z) for a total of 9 drops. evaluation standard 95% of the surface of the lead pads will be wet with solder. No interference in operation. No damage or cutting off.
terminal mechanical strength vibration
drop test
After the test, the part will meet specifications without any damage in appearance and the SPL should be within 10% of the i initial measurements.
ENVIRONMENT TEST
item high temp. test low temp. test thermal shock test condition After being placed in a chamber at +85C for 96 hours. After being placed in a chamber at -40C for 96 hours. The part shall be subjected to 10 cycles. One cycle will consist of: evaluation standard
temp. cycle test
The part shall be subjected to 10 cycles. One cycle will last 24 hours and will consist of:
After the test, the part will meet specifications without any damage in appearance except SPL. After 4 hours at 25C, SPL should be within 10% of the initial measurements.
