PRECAUTIONS
Stages
Pattern configurations
(Capacitor layout on panelized [breakaway] PC boards)
1. After capacitors have been mounted on the boards, chips can
be subjected to mechanical stresses in subsequent manufac-
turing 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 capacitors
should be carefully performed to minimize stress.
Precautions

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.
