How Does the FPC Factory Solve the Problem of FPC Overflow Adhesive

FPC factory may encounter the problems of FPC overflowing adhesive during the production process. This problem refers to that during the FPC manufacturing process, the adhesive overflows from the edge or pad of the FPC board, resulting in excess adhesive on the FPC. This problem may negatively affect the performance and reliability of the FPC, so steps need to be taken to address this problem. So how to solve this problem?

1. Control the amount of adhesive

In the FPC manufacturing process, the amount of adhesive should be properly controlled to avoid using too much adhesive. The problem of adhesive overflow can be reduced by reasonable adhesive spraying or roll coating technology.

2. Evenly distribute adhesive

The adhesive should be evenly distributed on the pad and the surface of the FPC board to avoid excessive adhesive gathering on one side or corner of the pad, resulting in adhesive overflow.

3. Optimizing process parameters

In the process of manufacturing FPC, the overflow of adhesive can be reduced by optimizing the process parameters. Such as controlling the viscosity of adhesive, the speed and pressure of spraying or roll coating, etc.

4. Use anti-spill adhesive

Anti-spill adhesive is a special adhesive that can be used in the FPC manufacturing process. This adhesive has a high viscosity and can form a film after the adhesive spills to prevent the adhesive from spreading further.

5. Check and remove adhesive overflow

During the FPC manufacturing process, if any adhesive overflow is found, it should be checked and removed in time. Special tools or solvents can be used to remove the adhesive overflow to ensure the quality and performance of FPC.

In addition, it should be noted that different FPC factories may have different solutions and process parameter adjustments. In order to solve the problem of FPC adhesive overflow, it is recommended to communicate with FPC factory with experience and professional knowledge, and formulate a solution according to the specific situation.
