What do I talk about when I talk about FPC connector circuit problems

For purchasers, they may usually purchase many different connector products, among which FPC connectors are one of the most common products, but do you know that FPC connectors are more prone to circuit problems?

1. In the circuit board of the FPC connector, it is used for two layers of single-sided PI copper-clad material, supplemented by adhesive glue that opens a window at a specific position, and then the opposite conductor of the two-layer separation structure in the local area. The circuit board to achieve high warpage performance in the layered area is called a substrate to generate a double-sided board.

2. For the double-sided circuit board in the FPC connector, it mainly uses the double-sided PI board copper-clad material. After the double-sided circuit is completed, a layer of protective film is added on both sides to become a double-layer conductor. circuit board.

3. The FPC connector also has a substrate to generate a single panel. It uses a pure copper foil material in the circuit manufacturing process, and then adds a layer of protective film to each of the two sides, thereby making only a single-layer conductor, but on the circuit board. Both sides of the circuit board have exposed conductors, so it is called a substrate to generate a single panel.

4. Regarding the single panel in the FPC connector, whether the single-sided PI copper coating is used to standardize the circuit is completed, and then a layer of protective film will be covered, and then a flexible circuit board with only a single-layer conductor of the connector will be formed.
