The rigid-flex pcb is combined with the hard board substrate in different areas of the soft board substrate (the conductive patterns need to be connected to each other in the soft and hard joint area), and then covered by the method of controlling the deep slab, laser cutting, etc. The hard board substrate on the board is removed, and a circuit board of the soft board substrate is exposed.

The biggest advantage of the rigid-flex pcb relative to the rigid pcb is the foldability. It can meet the bending and assembly in a small area, effectively reducing the volume and weight of electronic products.
The biggest advantage of the soft and hard bonding board relative to the soft board is that it can provide more welding area, which can ensure the increasingly complex electronic component assembly and welding requirements.
Of course, the soft and hard board has other advantages, such as:

1. Provide physical support for welded components
2. Provides better electrical performance than this method of soft-board soldering wire
3. Have better quality reliability and more.

There are many applications in soft and hard board, such as: aviation, aerospace, mobile phones, cameras, medical equipment, digital cameras, tablets, wearable devices, Bluetooth headsets, robots, etc., and we believe that in the future, hard and soft boards have More and more widely used in the market.
