Product Detail

What is Semi-Flex PCB?

The most traditional manufacturing process of semi-flex PCB is adopting the bending FR-4 materials and making PCB according to the traditional rigid PCB manufacturing process, and then using the deep milling technology to thin the areas that need to be bended so that it has a certain degree of flexibility, so as to meet the requirements of assembly bending connection.

SEMI-FLEX length Calculator: (2 x Π x bend radius) x (bend angle/360°)

For example, bending 5 times over an angle of 180 degree with a radius of 5mm requires a minimum length of the semi-flex part of 15,7mm
