What are the Production Technical Process of Rigid-flex PCB?
Rigid-flex PCB refers to the PCB formed by pressing the flexible PCB and rigid PCB together according to the relevant process requirements. So what is the production process of the rigid-flex board? 1. Cut Lamination: Rigid board base material cutting : Cut the large-area copper clad laminate to the size required by the design. 2. Flexible Base Material Cutting: Cut the original roll material (base material, pure glue, cover film, PI stiffener , etc.) to the size required by the design. 3. Drilling: Drill through holes for line connections. 4. Black Hole: The toner is used to make the carbon powder adhere to the hole wall , which can play a good role in connection and conduction. 5. Copper Plating: A layer of copper is plated in the hole to achieve conduction. 6. Counterpoint Explosure : Align the film (negative film) unde...
