FPC Bending Test Machine｜MIT Folding Endurance Tester

FPC bend test machines are designed to test the flexural strength and endurance of FCBs. The machine is capable of performing a reciprocating push-pull action with twists and turns, during which it evaluates the FCB’s ability to withstand bending and twisting without breaking or losing its electrical conductivity. The FPC bend test machine is equipped with adjustable speed, adjustable bending angle, automatic counting, and automatic shutdown when the set number of times is reached.

The importance of FPC bend test machines goes beyond mere durability testing. The test results provide critical data for manufacturers of FCBs to improve their product quality. Specifically, FPC bend test machines evaluate a variety of properties, including the flexural strength, ductility, uniformity, and resistance to mechanical stress. By producing reliable and reproducible data, the machine helps to ensure the quality of FCBs, protecting manufacturers’ reputation, and helping to prevent costly product recalls.

The FPC bend test machine works based on the principle of cyclic bending. It involves repetitively bending the flexible circuit board, simulating the conditions that the board will experience when incorporated into an electronic device. The machine applies a fixed force load to the FCB and then cycles through various bending angles to observe how the board reacts to different stresses. The FPC bend test machine is capable of testing FCBs up to a certain degree of flexibility, after which the board may break or lose electrical conductivity. The machine is adjustable, allowing users to set different bending angles, speed of cycling, and determine how many cycles occurs before the test stops.
