Flexible PCB Series

1layer flexible PCB

A single-layer flex board is the most basic and consists of a flexible polyimide film laminated to a thin sheet of copper. The copper layer is then chemically etched to produce a circuit pattern specific to your specific design requirements.

2layer flexible pcb

PCBMay provides 2 layer flexible PCBs, which are becoming a regular choice for applications across various industries. These circuit boards comprise 2 conductive layers that are placed on a polyimide base and are also popular flexible PCBs.

3layer flexible PCB

A 3 Layer Flexible PCB is a patterned arrangement of 3 copper printed circuitry that connected with plated-through holes. A 3 Layer Flex PCB can be with or without stiffener since stiffener has no effect on flex circuits manufacturing.

4layer flexible PCB

Flexible printed circuit boards are now prominently used in the electronics industry. Being one of the leading manufacturers of these circuit boards, PCBMay provides 4 layer flex printed circuit boards.
