What are some precautions for Mobile Devices Micro Screws?

2025,08,14
When bending sheet metal for Mobile Devices Micro Screws, the internal angle (R) should ideally be greater than or equal to 1/2 the material thickness. If the R is not formed, after several punching cycles, the right angle will gradually disappear, and a natural R angle will form.

The R angle will then be slightly longer on one or both sides. Sheet metal parts are prone to deformation after bending. To prevent deformation, 45-degree reinforcing ribs can be added to the bends to increase strength, without interfering with other parts.
Sheet metal parts are generally difficult to maintain a straight line when they are narrow and long, and are more likely to deform under stress. Therefore, one side can be bent into an L shape or both sides into a U shape.
This maintains strength and straightness. However, L and U shapes often cannot be connected from beginning to end. Mobile Devices Micro Screws can use appropriate ribs to increase strength.
At the transition between flat and curved surfaces, a narrow hole should ideally be created, or the edge of the hole should be rolled back after the bend to prevent burrs. The narrow hole should be wider.
