Notice of Soldering and Mounting on PC Board

For mounting SMDs on a PC board, supporting pin is suggested for use (refer to figure b) to avoid cracks caused by

external stress(refer to figure a).

If circuit bending is needed for PC board design, please refer to figure (c) for mounting positions to avoid cracks caused by stress imposed

on the product. O means better, △ is acceptable, and X is worst.

During circuit bending, please locate SMDs horizontally to the direction in which stress act to avoid its cracks (refer to figure d).
