What are the functions of FPC impedance PCB board

FPC impedance board is a product that can effectively block AC power. Choosing a high-quality FPC impedance board manufacturer for cooperation can guarantee the quality requirements of FPC products and increase customers' trust in their own products. So what are the functions of the FPC impedance board? Let's briefly understand:

When the electronic equipment (computer, communication machine) is operated, the information sent by the drive component will pass through the FPC transmission line to reach the takeover component. When the information is transmitted on the information line of the printed board, its characteristic impedance value Z0 must be equal to that of the head and tail components. The "electronic impedance" can be matched, and the "energy" in the information can be transmitted intact.

2. Once the quality of the printed board is poor and Z0 surpasses the government, the information transmitted will have problems such as reflection, loss, attenuation or delay. When it is critical, the wrong signal will be transmitted and the machine will crash.

3. Strictly select the board and control the production process, so that the Z0 on the multilayer board can meet the specifications required by the customer. The higher the electronic impedance of the component, the faster its transmission speed, so the Z0 of the FPC will also increase accordingly to meet the requirements of the matching component. FPC multilayer boards that pass Z0 can be regarded as passing products required by high-speed or high-frequency signals.

The above is the function of the FPC impedance board, I hope to help you.
