5.Washing
Excessive ultrasonic oscillation during cleaning can cause the PCBs to resonate, resulting in cracked
chips or broken solder joints. Take note not to vibrate PCBs.
6.Electrical Test on Printed Circuit Board
1. Confirm position of the support pin or specific jig, when inspecting the electrical performance of
a capacitor after mounting on the printed circuit board.
1-1. Avoid bending printed circuit board by the pressure of a test pin, etc.
The thrusting force of the test probe can flex the PCB, resulting in cracked chips or open solder joints.
Provide support pins on the back side of the PCB to prevent warping or flexing.
1-2. Avoid vibration of the board by shock when a test pin contacts a printed circuit board.
