PCB connectors have semiconductor contacts that are soldered to the PC's motherboard, making them perfect for use in applications where space and weight limitations are an issue. They are also used in high-volume assembly lines and in computer motherboards. These special connectors are available in a variety of different configurations and are useful for a number of applications, from digital to synchronous serial and synchronous digital or IGBT cables. They can also be used in conjunction with modular components, as they are available in a variety of different types of crimp and plug designs.

Most common types of PCB connectors are push-fit connectors. These are made by simply pushing the plug into the connector, which then holds the cable securely in place. Some push-fit connectors use an epoxy liner to ensure a tight fit, while others rely on a rubberized friction-rubber layer to keep the connection secure. The friction-rubber layer is generally made from P.R.I.D. plastic, which is extremely wear resistant. Other types of connector may include ribbon connectors, which require no insertion of mechanical Plug-in terminal block devices, and gold-plated connectors, which can only be installed with specific gold-titanium alloy devices.

Another common type of PCB connectors are printed circuit board connectors, which are used in personal computers, hand held PCs and other electronic devices. Printed circuit board connectors are also called trace connectors, because they connect two or more conductors to a fitting surface. They have two faces - one surface and one terminal. The common PCB layout has terminals at the front of the board, while tabs or sockets are positioned on the back. All printed circuit board connectors are produced with a standard sized hole for insertion, and often a grease seal is also included to ensure a long life span.

Floppy disk and DVD-ROM connectors are also produced by many companies and are used in conjunction with PCBs. Floppy disk and DVD-ROM are a popular choice because they can be easily inserted into the computer, and because they offer the best compatibility with other computer equipment. Pin header and JMP connector designs are particularly popular for connecting video and audio devices to the computer. Other types of printed circuit board connectors that are frequently used are thermistor based ones, which provide thermal control, ground loop configurations and are used in automated welding process as well as refrigeration applications.

In addition to all the connector types described above, manufacturers sometimes use a special desktop system to test components for maximum compatibility and efficiency. This is known as PMMI (PrixMEM), and a testing utility for PCB connectors is called PMCK. These two methods have been developed to specifically test various types of connectors based on their physical properties, such as the thermal resistance, magnetic field strength, and frequency response. With PMMI, manufacturers can determine the effect of temperature on the performance of a connector and can improve its temperature resistant properties.

A final category of printed circuit boards that are commonly used today is the thermal resistant thermoplastic connectors. This type of connector has special properties that make it highly resistant to heat, which allows it to be placed close to electronic components when they are being manufactured. The material used for the connectors are usually thermoplastic polymers, plastics, and polyurethane, which have high tensile strengths. One example of such material is polyester. Thermoplastic circuit boards can sometimes include solenoid controlled bidirectional mating pairs.
