Enig / Hasl Rigid Flex Immersion Tin Pcb

What is rigid flex PCB?

Printed circuit boards can be divided into rigid printed boards and Rigid-Flex Board according to the materials produced. Rigid printed boards include phenolic paper laminates, epoxy paper laminates, polyester glass mat laminates, and epoxy glass cloth laminates. The flexible printed circuit board is also called the flexible printed circuit board ,6 layer Rigid-flex Immersion Gold PCB or FPC. The flexible printed circuit board is made of polyimide or polyester film as a substrate with high reliability and high flexibility. . This kind of buile-up printed board has good heat dissipation, which can be bent, folded, rolled, and can be moved and stretched freely in three-dimensional space. FPC can be used to reduce the volume, achieve lighter weight, miniaturization, and thinner, so as to realize the integration of Electronic Components devices and wire connections. FPC is widely used in Electronic connectors,electronic computers, communications, aerospace and household appliances and other industries.
