4L Flexible Printed Circuit Board
Flexible printed circuits are circuit boards that have the ability to bend or twist. From this assertion, it is obvious that they are distinguished by a flexible construction. That is why electronic engineers and designers use them in applications that demand for their qualities. They are also referred to as flex circuits and are mostly used in small electronic applications. Since they are characterized by their ability to bend, flexible printed circuits are made of flexible substrate such as polyimide. Another important quality of flexible printed circuits is that they have superior heat dissipation than printed circuit boards. It is this quality that makes it possible for the electronics that use it to stay in quality condition for a long time.
HSX products cover 1~32L FR-4 PCB, IMS PCB,HDI Boards, high frequency PTFE boards and Rigid-flex boards etc. It provides flexible quick turn production services (12 hours to72 hours), as well as small volume to big volume PCB manufacturing.Products are widely used in high-tech fields such as communications, power supplies, computer networks, digital products, industrial control, science and education, medical devices, and aerospace.
