What are the precautions for the use of FPC flexible circuit boards
May 26, 2022
Precautions for the use of FPC flexible circuit boards:
1. FPC flexible circuit boards will be treated with surface coating, which can effectively prevent oxidation. There are certain requirements for the environment during storage. The temperature should be controlled below 25°C, and the humidity should be controlled within the range of 50%-70%.
2. The FPC flexible circuit board has strong folding resistance, but the exposed part of the conductor is not suitable for bending, nor can it be directly bent on the via hole. The FPC ink-type protective layer is strictly prohibited from exceeding 90°C during the assembly process. Bending, let alone 180°C bending, may cause problems such as wire breakage.
3. The areas where the stress of the FPC flexible circuit board is concentrated, such as the cover film, the gold finger end, the corner of the shape, etc., are prone to line breakage during the assembly process, so special attention should be paid when using it.
In the test, the high-current shrapnel micro-needle module can be used for connection and conduction, which can effectively transmit large current and maintain a stable connection in the range of 1-50A; it can also cope with small pitches and ensure no Card pin, non-stop pin, make the FPC flexible circuit board test stably.
