Flexible printed circuit boards have been the solution for connections that need to be movable, that require little space and/or weight, or that require a fast data connection. They usually have only the passive function of transmitting signals. They replace cables and are often found as a part of switches in keyboards, in LED lighting, PC and mobile antennas, various sensors such as motion controls or drug delivery sensors and in wearables.

Flexible PCBs, typically based on a thin polyimide (PI) film, are multifunctional and can be produced as single, double or multilayer with plated through holes and surface treatment similar to rigid circuit boards. LPKF’s ProtoLasers play a key role in the prototyping of flexible PCBs. LPKF has carried out various tests to determine which laser system is best suited for which material application.
