Discussion on the design function of FPC impedance plate

FPC impedance plate is a product that can effectively block AC power. Choosing a high-quality FPC impedance plate manufacturer for cooperation can ensure the quality requirements of FPC products, and thus increase customers' trust in their own products. So what is the role of FPC impedance board in design?



1. When the electronic equipment (computer, communication machine) is operated, the signal sent by the driver will reach the receiver through the FPC transmission line. When the signal is transmitted in the signal line of the printed board, its characteristic impedance value Z0 must match the "electronic impedance" of the head and tail components, and the "energy" in the signal will be completely transmitted.



2. Once the quality of the printed board is poor and Z0 exceeds the tolerance, the transmitted signal will have problems such as reflection, dispersion, attenuation or delay. In serious cases, the wrong signal will be transmitted and the machine will crash.



3. Strictly select the plates and control the production process, so that the Z0 on the multi-layer plates can meet the specifications required by customers. The higher the electronic impedance of the element is, the faster the transmission speed will be. Therefore, the Z0 of FPC must also be increased to meet the requirements of matching elements. Z0 qualified FPC multilayer boards are qualified products required by high-speed or high-frequency signals.
