02. Precautions for product design
02-1. Considerations in mechanical design
1) Position of the connector on a board
Rigid boards tend to warp in a direction perpendicular to the rolling direction
during the production process. Poor soldering may occur depending on the
warping direction. Make sure to place the connector in a direction which reduces
warpage.
2) Position of the connector in the mounting process
Design multi-pin connector layouts that do not require a swinging movement
during pickup and mounting.
In many cases, deviation of the connector mounting position is caused by the
inertia of the swinging movement of the mounter. A layout that does not require
swinging is thus required.
