PCB News - The advantages of multilayer rigid-flex board

Multilayer rigid-flex board is an innovative circuit board that combines rigid-flex boards using a special process.

In the design of the board, a flexible circuit layer is first made, and then it is combined with a layer of rigid circuit board through a special lamination process. This combination method not only maintains the flexibility of the flexible circuit board but also strengthens the entire structure through the rigid circuit board, improving the reliability and stability of the circuit board. The multi-layer rigid-flex board has found a balance between flexibility and rigidity, greatly expanding the design space of electronic products.

Multilayer rigid-flex board is made by stacking multiple layers of sheets, among which the PP (polypropylene) layer is one of the materials. PP is a polymer material with good physical properties and chemical corrosion resistance, commonly used in the manufacturing of electronic products. The multilayer rigid-flex board consists of multiple layers of flexible circuit layers and multiple layers of rigid circuit layers. The PP layer is usually used as the insulation layer between the flex circuit layers to enhance the insulation performance of the circuit board. By combining the PP layer with other circuit layers, the stability and reliability of the circuit board can be effectively improved.
