What is the difference between FPC connectors and PCD connectors?

FPC connectors and PCD connectors are two common connectors in electronic equipment, they are different in physical structure and electrical properties. In this article, we will introduce the difference between FPC connectors and PCD connectors from a number of aspects. Physical structure of the FPC connector is a flexible circuit board connector, which is mainly composed of a set of elastic contacts and plastic sockets. Contact sheet is usually a thin film material, they are in contact with the conductive part of the circuit board, so as to realize the electrical connection. Plastic sockets are used to protect the contacts and guide the insertion of the flexible circuit board.FPC connectors usually have a small size and low insertion and extraction force, suitable for connecting flexible circuit boards that need to be inserted and removed frequently.PCD connectors are pinhole connectors, which are mainly composed of two parts: the socket and the pins. Receptacle is a metal shell, the internal contains a number of pinholes and conductive parts, they are in contact with the pin. The pins are metal pins, usually tapered or spherical, which are inserted into the pinholes of the socket.PCD connectors usually have larger dimensions and higher insertion and extraction forces, and are suitable for connecting circuits that require high reliability and high current capacity. Electrical Properties FPC connectors and PCD connectors also differ in their electrical properties.FPC connectors are typically used to transmit low-speed, low-power signals, which typically have a resistance of a few hundred ohms to a few thousand ohms.FPC connectors can also transmit low-voltage and low-current signals.In contrast, PCD connectors can transmit low-voltage and low-current signals.FPC connectors can be used to transmit low-power signals. In contrast, PCD connectors can transmit signals with higher currents and higher voltages and typically have lower resistance values of tens of milliohms to hundreds of milliohms. Areas of Application Because of their flexible design and small size, FPC connectors are commonly used to connect flexible circuit boards in laptops, tablets, smartphones, and other portable devices.FPC connectors are also widely used in LCD screens, cameras, touchscreens, and other devices that require a reliable, flexible connection. In contrast, PCD connectors are typically used to connect circuit boards in stationary electronic devices, such as servers, computer motherboards, industrial control systems and medical equipment.
