1.Test experiment bulb: 4pcs blue LED backlight, parallel to PCB (80mA at 3.0 - 3.2V) backlight voltage can be changed to 12V
2.Soldering
conditions: Place the terminal about 3mm into the tin plate at 230°C
for 3.5 seconds. After the test, the 7-14 items remain normal.
3.Soldering
temperature: The temperature of the hand-held soldering gun is 350 °C,
the terminal is in contact for 3.5 seconds, and the front end of the
terminal is about 3 mm in contact with the soldering gun. After the
test, the 7-14 items remain normal.
4.
Anti-static: Test with the dry nylon cloth on the surface of the
transparent cover in the same direction three times. The difference
between the markings on the scale is less than 1/3 of the scale length,
and the zero return position after three seconds.
