A.  Introduction:

This tester is doing ±135° folding test when the specimens stand under the certain load. When reaching the settled times, or the specimens broke, or the circuit broke (only for conductive material), stop the running process and record the folding times.

It is for the circuit soft board, copper foil, paper and other folding life test. The folding angle and speed can be set up. When the specimens broke, the machine will stop automatically and keep the max. times. It also can coordinate with voltage circuit to test the stop function. Use different grips to change the R angle and the space of the folding.
