Laser Processing of Flexible Circuits

摘要

The IPC (Association Connecting Electronics Industries) defines a flex circuit as "a patterned arrangement of printed wiring utilizing a flexible base material with or without flexible cover layers." As the name implies, the final product is designed to be bent, either as part of the assembly process or in a dynamic way between two moving parts. In the second configuration, the circuit may see thousands of repeat motions over the lifetime of the device, so it is critical that the devices are simple and error free. Flexible circuits provide advantages such as economy in weight and space, enhanced reliability, better temperature cycling ability and the ability to connect moving devices without the use of cables.
