Green PCB

Green PCBs are the most common type of printed circuit boards, distinguished by their green solder mask—a protective layer applied to the substrate to insulate copper traces, prevent short circuits, and resist environmental damage. The green color comes from epoxy resin mixed with a green pigment (t

Flexible Circuit Boards

Flexible circuit boards (PCBs) are thin, bendable electronic substrates designed to fit into compact or irregularly shaped spaces, offering versatility in device design that rigid PCBs cannot match. Constructed from polyimide (PI) or polyester films (typically 25–125 μm thick) as the base material,
