MECHANICAL CHARACTERISTICS
item
test condition
evaluation standard
solderability
Lead terminals are immersed in solder bath of
+270±5oC for 3±1 second
90% min. lead terminals will be wet with solder
No interference in operation.
soldering heat resistance
The product followed the reflow profile to test
its reflow thermo-stability.
terminal mechanical
strength
Lead pads will be soldered on the pc board, and
the force 9.8N(1.0Kg) will be applied behind the
part for 10 seconds.
No damage and cutting off
vibration
The part will be subjected to a vibration cycle of
10Hz to 55Hz to 10Hz in a period of 1 minute.
Total peak amplitude will be 1.52mm(9.3G). The
vibration test will consist of 2 hours per axis in
each three axes (X,Y, Z). Total 6 hours.
After the test the part will meet specifications
without any damage in appearance and performance except SPL. SPL would be in ±10dBA
compared with initial one.
drop test
The part only shall be dropped from a height of
75cm onto a 40mm thick wooden board 3 times
in 3 axes (X,Y, Z). Total of 9 times.
