FPC bending testerIt is a device specifically designed to test the durability and reliability of flexible circuit boards (FPCs) under repeated bending stress. It evaluates the mechanical strength and electrical stability of FPC by simulating its bending motion in practical applications such as foldable phones and wearable devices, and is a key testing instrument in FPC production and research and development.
FPC bending testerThe workflow is as follows:
Clamping system: Fix the FPC sample to ensure no looseness or displacement during the testing process, avoiding data deviation caused by unstable clamping.
Transmission system: Drive the fixture to perform reciprocating motion at a set angle, speed, and frequency, simulating the actual force situation of FPC in folding screen phones, wearable devices, and other scenarios.
Load system: Real time monitoring of bending force, deformation, and resistance changes during the bending process, quantitatively evaluating the flexural performance of FPC.
Control system: Set test parameters (such as angle, speed, frequency) through PLC or touch screen, and have functions such as automatic shutdown when disconnected, data export, etc., to improve testing efficiency and safety.
Test type:
Bending life test: Set a fixed bending angle, speed, and radius, and perform reciprocating bending on the FPC until its electrical performance fails or reaches the preset number of times to evaluate its service life.
Dynamic bending test: Simulate the continuous opening and closing or swinging of the product during use, such as the opening and closing of foldable phones and the sliding of sliding phones.
Static bending test: Fix the FPC in a specific bending state and place it for a long time to test its creep or stress relaxation under continuous stress.
Environmental adaptability testing: Some models can be combined with a temperature and humidity chamber to conduct bending tests in extreme environments such as high and low temperatures, humid and hot conditions, to evaluate the impact of environmental factors on the bending resistance of FPC.
