1)The function EEPROM is qualified.
2) The on resistance of the whole line is less than 3 Ω.
3) Voltage withstand confirmation OK (AC 500V, 2S, < 5mA).
4) Use LCR meter to test the matching consistency of capacitance between lines: ≤ 150pF.
5) Insulation impedance test ≥ 20m Ω, (DC 300V, 10ms).
6) The plug and the female socket are connected smoothly without obvious interference.
