Reliability Test Items
1. Mechanical Performance Tests
Orient the sample in any attitude and drop it three times from a height of 75 cm onto a hardwood board with a thickness of 3 cm
|Vibration||Subject the sample to 1.5-minute cycles of frequencies of 10 to 55
Hz and amplitudes of 1.5mm for two hours in each of the X,Y, and
Z directions, or 6 hours in total.
|Tensile strength of terminal||Apply a 1.5Kg tensile load to each terminal and sustain it for
|Apply a 0.5 Kg load to one of the terminals, and after tilting the
main unit for 90°,restore to its original attitude. Then, tilt it in an
opposite direction for 90°,and restore to its original attitude
|Solder ability||Dip terminals in RMA flux for5 ± 0.5 seconds. Under room
temperature. Dip terminals in a 230±5℃ solder bath for 5±0.5
seconds. The solder shall leave an undipped terminal length of 2 mm at their base .
|Dip terminals in a 260±5℃ solder bath for 10±0.5 seconds.
The solder shall leave an undipped terminal length of 2 mm at their
|Leaking Test||Take measurements with a helium leakage detector,or measure
insulation resistance under pressure.
|A||Any variation between the pre- and post-test frequencies shall remain within ±5ppm. The
post-test equivalent series resistance shall remain within its specified tolerance range.
|B||Any variation between the pre- and post-test frequencies shall remain within ±10ppm.
The post-test equivalent series resistance shall remain within its specified tolerance range
|C||After each test, no visible damage shall be manifested, nor shall the hermetic seal break down.|
|D||At least 90% of each dipped area shall be covered by fresh solder|
/s Max or IR≥500MΩ
Remark:Measurements shall be taken at 25±2℃,and after each test, the sample be exposed
to two hours at 25±2℃
