FPC Connector introduction and description

The inside of an FPC Connector’s plastic body is an equally spaced sheet-like barrier structure that allows terminals to be arranged at a small pitch and to provide retention after assembly. According to the product application, the plastic body should have sufficient strength and toughness, and undergo warping deformation before and after SMT welding.

 

In the design process of the FPC Connector, the structure and selection of raw materials for the plastic component directly affect the functions and applications. The plastic body should have the ability to withstand impact as well as high temperatures during infrared reflow soldering. Plastic that is too soft may cause low dimensional accuracy after molding, and easy deformation, resulting in poor finished products. On the other hand, plastic that is too hard may crack due to impact. Therefore, Molex uses good plastic materials that do not only have high temperature resistance and low thermal expansion coefficient, but are also suitable for injection of small-pitch thin-wall types, and can maintain a certain degree of strength and toughness.

 

A latching mechanism works with the plastic body when the FPC Connector is inserted. It locks the FPC to maintain contact force and sufficient plus excellent rigidity. The terminal is the contact part of the FPC Connector. In order to achieve high-density arrangement of the connector and a more stable contact performance, the FPC Connector terminal adopts a narrow-plate contact method, along with a material made of phosphor bronze with good electrical conductivity and mechanical strength.
