Solderability
Lead terminals are immersed in
rosin for 5 seconds and then
immersed in the solder bath at
+250 ±5for 3 ±1 seconds.
90% min. lead
terminals shall be wet
with solder
No interference in
operation.
Soldering Heat
Resistance
The product follows the reflow
temperature curve to test its
reflow thermal stability.
Terminal Mechanical
Strength
Lead pads shall be soldered on
the pc board, and the force of
9.8N (1.0kg) shall be applied to
the part for 10 seconds.
No damage and
cutting off
Vibration
Drop Test
The part shall be subjected to a
vibration cycle of 10Hz to 55Hz
to 10Hz in a period of 1 minute.
Total peak amplitude shall be
1.52mm(9.3G). The vibration test
shall consist of 2 hours per axis in
each three axes (X,Y,Z).
Total 6 hours.
The part is dropped from a height
of 75cm onto a 40mm thick
wooden board 3 times in 3 axes
(X,Y,Z). Total of 9 times.
After the test, the
part shall meet
specifications without
any damage in
appearance and
performance except
SPL. The SPL should
be in ±10dBA
compared with initial
one.
