solderability
Lead terminal are immersed in rosin for
5seconds and then immersed in solder bath of
+230±5oC for 3±0.5 second
90% min.lead terminals will be wet with solder
No interference in operation
soldering heat resistance
Lead terminal are immersed in soldering bath of
+230±5oC for 3±0.5 second.
terminal mechanical
strength
Apply the terminal with 1 KG of tension for 1
minute
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 will 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.
