Introduction:
Rigid flex PCB have been used in the military and aerospace industries for more than 20 years. In most rigid flex circuit boards, the circuitry consists of multiple flexible circuit inner layers selectively attached together using an epoxy pre-preg bonding film, similar to a multilayer flexible circuit. However, a multilayer rigid flex circuit incorporates a board externally, internally or both as needed to accomplish the design.
Rigid flex PCB combine the best of both rigid boards and flexible circuits integrated together into one circuit. The two-in-one circuit is interconnected through plated thru holes. Rigid flex circuits provide higher component density and better quality control. Designs are rigid where extra support is needed and flexible around corners and areas requiring extra space.
Flex and Rigid-Flex applications also provide increased reliability. Mean time between failure rates (MTBF) typically exceed those of standard PCB sets with discrete wires and connectors, often becoming the choice of companies and engineers alike for its dependable and consistent performance.
Types:
Flexible Printed Circuit Boards with 8 layers rigid PCB
Single-Sided Flexible with rigid PCB board up to 6 layer

HDI PCB is among the fastest growing PCBs on the market because it meets complex design needs. This kind of high density interconnect printed circuit board allows designers to place more components in a smaller area. Having a higher circuitry density than conventional PCBs, it's able to incorporate finer lines and spaces, smaller vias & capture pads, and higher connection pad densities. It contains blind/buried vias and is often with 6 mil microvias.
HDI custom PCB is widely used to reduce the weight and overall dimensions of products, as well as enhancing the electrical performance of the device. It's regularly found in mobile phones, touch-screen devices, and 4G network communications.
XCEPCB offers HDI custom PCB fabrication with microvias down to 4 mil; laser drilling is required.
