5. Washing

Excessive ultrasonic oscillation during cleaning can cause the PCBs to resonate, resulting in cracked chips or broken solder joints.

Before starting your production process, test your cleaning equipment / process to insure it does not degrade the capacitors.

6. Moisture Proof (Application: GQM033 rated voltage 200V products)

To prevent the migration and degradation due to flux residue when a voltage more than DC100V is applied to the capacitor, keep parts under low moisture condition with resin coating and the equivalent.

7. 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 the printed circuit board by the pressure of a test-probe, 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. Install support pins as close to the test-probe as possible.

　1-2. Avoid vibration of the board by shock when a test -probe contacts a printed circuit board.
