Is there any special cleaning liquid for socket adapters?
Lead-free chip more easily oxidized and thus contaminate the test pin. Mild cleansing agents can be used to clean the socket adapters. Ultrasonic cleaning machines can be used regularly (must not use strong cleaning agents such as thinner, benzene, acetone, etc.). Note that cleaning should be done at room temperature, time of 2-3 seconds, otherwise it may damage the socket.
