Stages
（Capacitor layout on panelized [breakaway] PC boards）
Pattern configurations
1. After capacitors have been mounted on the boards, chips
can be subjected to mechanical stresses in subsequent
manufacturing processes （PCB cutting, board inspection,
mounting of additional parts, assembly into the chassis, wave
soldering the reflow soldered boards etc.） For this reason,
planning pattern configurations and the position of SMD ca-
pacitors should be carefully performed to minimize stress.
Precautions

on the capacitors can vary according to the method used. The following methods
are listed in order from least stressful to most stressful: push-back, slit, V-grooving,
and perforation. Thus, any ideal SMD capacitor layout must also consider the PCB
splitting procedure.
