Overview
Cometech QC-104 MIT Folding Endurance Tester evaluates a material’s folding endurance strength by measuring how many bending cycles it can withstand under tension and a defined bending angle before failure.
It is commonly applied to paper and flexible materials such as aluminum foil, copper foil, and ductile circuit boards (flexible printed circuits).
For conductive materials, the QC-104A variant can detect break / loss of electrical conductivity and automatically stop the test while showing the final bending count.
