2. Check the cropping method for the printed circuit board
in advance.
2-1. Printed circuit board cropping shall be carried out by
using a jig or an apparatus to prevent the mechanical
stress that can occur to the board.
(1) Example of a suitable jig
Recommended example: the board should be
pushed as close to the cropping jig as possible
[Outline of Jig]
and from the back side of the board in order to
minimize the compressive stress applied to the
capacitor.
Not recommended example: when the board is
pushed at a point far from the cropping jig and
from the front side of board as below, the
capacitor may form a crack caused by the tensile
stress applied.

(2) Example of a suitable machine
An outline of a printed circuit board cropping
machine is shown as follows. Along the lines with
the V-grooves on the printed circuit board, the top
and bottom blades are aligned to one another
when cropping the board.
