Features of Flexible PCBs from Raytech
Key Features of Flexible PCBs
Fine Pattern Flexible PCBs
Raytech specializes in flexible PCBs known as "fine pattern" types. These are built using a semi-additive process (SAP), which involves UV exposure on the substrate, electrolytic plating on the dry film, followed by copper etching. This enables high-density interconnects and compact circuit design.
Flying Lead Flexible PCBs
Raytech also manufactures flying lead flexible PCBs. These boards are designed for F-CLIP mounting by removing the base film at the mounting lead section, creating a flexible lead. The use of interlayer blind via connections helps ensure electrical stability.
Support for Single-Sided and Double-Sided PCBs
Raytech offers both single-sided and double-sided flexible PCBs, all using polyimide film. For double-sided PCBs, surface finishes such as gold plating and direct gold plating are also supported.
