FPC Flex Durability Tester
Category：Abrasion Tester
Introduction
The FPC Flex Durability Tester is designed to evaluate the bending durability and fatigue life of flexible printed circuits (FPC), flexible flat cables (FFC), and similar flexible electronic components. The tester simulates repeated bending at controlled angles, speeds, and strokes to assess mechanical reliability and electrical continuity under cyclic flexing conditions. It is widely used in product development, quality control, and reliability testing of flexible electronic interconnects.
Application
(1) Flex durability testing of FPC (Flexible Printed Circuits) used in mobile phones, tablets, laptops, and wearable devices.
(2) Fatigue life evaluation of FFC cables used in displays, cameras, and hinge structures.
(3) Reliability testing of flexible interconnects in automotive electronics and dashboards.
(4) Bending endurance testing of flexible circuits used in medical devices and precision instruments.
(5) R&D validation of new flexible substrate materials and circuit designs.
(6) Quality control testing during mass production of flexible electronic components.
(7) Electrical continuity monitoring during cyclic bending until failure.
Standards
(1) ASTM F392 – Standard Test Method for Flex Durability of Flexible Circuits.
