Flexibility is the most obvious advantage for flex PCB, but we should maintain a degree during use, not just bend casually, so what should we pay attention to when bending?
- Although the FPC can be bent, if it is bent at 180°, this may cause damage to the copper traces, and it lead to open or short circuits.
- Most of the ink-type protective layer is not resistant to bend, such as text/silk screen, marking, solder mask, etc. It is strictly prohibited to have more than 90° bending action in the assembly process.
- The corners of the FPC outline, which are prone to tearing during the assembly process, reminding users to pay attention to it.
- The exposed part of the FPC is subjected to surface plating treatment, such as gold/gold plating, etc., the focus is on preventing oxidation. This area is not suitable for bending.
- Although there is a stiffener design in the golden finger plug-in area, it is still not suitable for bending in this area. Special attention should be paid to the assembly process.
- Do not bend directly on the via area of FPC.
