Today, we're talking about rigid-flex PCB.
A rigid-flex PCB is a combination of rigid boards and flexible circuits, the latter creating flexible inter-connects between the rigid boards to which they are laminated by means of bond plies. Such as the following diagram is rigid-flex drawing.
Both ends are rigid board, flexible circuit is in the middle.
The flexible circuit is manufactured separately and bonded to the rigid boards, either symmetrically, i.e., in the middle of the rigid boards, or asymmetrically, i.e., to the outer side of the rigid boards to be interconnected.
Plated-through holes are provided in the rigid sections of the rigid-flex PCB to establish electrical connection between the flexible circuit and the electronic circuits of the rigid boards. The processes are similar to those used when manufacturing rigid multilayer boards.
The first one is a 4-layer flex-rigid board. The flexible circuit is in the middle, and the two sides are rigid plate and symmetrical structure. The solder mask is green and the surface is treated with gold.
The second sample is a 6-layer flex-rigid board. The first layer and the second layer are the flexible board, located at the top of the flex-rigid board. The flexible board and the rigid board are connected by 1080 prepeg, and the third layer to the sixth layer is the rigid board. What we used is FR-4 from ITEQ Company: IT-180A. The inner layer is 0.5OZ, the outer layer is 1OZ, the whole finished plate thickness is 1.5mm, and the surface finish is immersion gold.
