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.
Tends to warp in the
manufacturing (lateral) direction.
2) Position of the connector in the mounting process
Please design multi-pins 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.
● Example of a connector layout requiring a swinging movement in the mounting process
Embossed tape
Make sure that connector positioning and FPC length are appropriate to
prevent diagonal insertion of the FPC. FPC may become loose due to drop
impact and vibration depending on size, weight, and turning of FPC board.
Carefully check the FPC condition in the device. Design the device to prevent
the FPC from detaching.
