Electrical test on printed circuit board

Safety Application Guide for Multilayer Ceramic Chip Capacitors

Mounting

Handling after mounting

Confirm that the printed wiring board is fixed with support pins or specific jig, when inspecting the electrical performance of a mounted capacitor.

(1)　Avoid bending the printed circuit board by the pressure of a test pin, etc.
(2)　Avoid vibration of the board due to test pin contact.

When an electrical test is carried out on a printed circuit board, excessive pin pressure to prevent loose contact may bend the board and cause cracks in capacitors or peeling of electrodes.
See the following figures showing how to avoid bending a printed circuit board.
