FPC Flex Durability Tester

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.

Features

(1) Stepper motor drive ensures high positioning accuracy, low noise, and long-term stable operation.

(2) Program-controlled automatic origin reset, eliminating manual fixture repositioning.

(3) Touch screen controller for intuitive parameter setting and program input.

(4) Test angle, speed, test cycles, and motor return-to-origin can be digitally set via touch screen.

(5) Automatic counting with preset test cycles and auto-stop upon reaching the set value.

(6) Electrical conduction detection function with automatic stop when circuit disconnection occurs.

(7) Automatic stop when the specimen bends to the broken line and loses conductivity.

(8) Upper and lower moving fixtures simulate realistic flexing conditions.

Technical Parameters

Test Procedure

(1) Fix the FPC or flexible cable specimen securely in the upper and lower fixtures.

(2) Set the bending angle, test speed, stroke, and target number of cycles on the touch screen.

(3) Enable the electrical continuity detection function if required.

(4) Start the test; the specimen is repeatedly bent according to the preset parameters.

(5) The system automatically counts cycles and monitors electrical continuity.

(6) The test stops automatically when the preset number is reached or when electrical disconnection occurs.

(7) Inspect the specimen and record bending life and failure mode.

Maintenance Information

(1) Regularly inspect fixtures to ensure secure clamping and accurate alignment.

(2) Keep the touch screen and control system clean and free from dust.

(3) Periodically check motor operation and mechanical transmission components.

(4) Verify electrical continuity detection function before critical tests.

(5) Store the equipment in a dry, vibration-free laboratory environment.
