Screw Installation Precautions:

1. For module positioning holes, use only three screws—leave one corner free for movement. Avoid over-tightening. Use plastic screws or install with soft washers; never use metal screws, as they may cause board deformation during operation.

2. If the product is a bare board secured to your equipment with screws, avoid mounting it on uneven screw positions that could cause the device to bend or deform. Prolonged exposure to such conditions may also lead to unpredictable malfunctions.
