Tensile Strength, Breakage, and Peeling: Three Tests for Inspecting Electronic Components

A need: to verify the mechanical behavior of components

The manufacturer wanted to subject its products to various types of stress. Therefore, the requirement was not limited to measuring maximum force: it was necessary to be able to apply a load for a few seconds, continue a test until failure, or perform a peel test.

To meet these three requirements, the selected solution combines a Stentor II testing machine, force sensors of various capacities, appropriate accessories, and the Califort control and data acquisition software.

Holding Under Load: Apply, Maintain, Release

The test involves applying a specified force to the component, maintaining that force for a few seconds, and then releasing it. This sequence verifies the component’s performance under the load and duration conditions selected for the test.

Failure: Observing Behavior Until Failure Occurs

During this test, the component is subjected to stress until it fails. Recording the force allows us to track how the force changes over the course of the test and to observe the drop in force associated with failure.

Peeling: Measuring the Peel Force

The peel test is designed to measure the force required to peel the material away. It requires a test setup adapted to the product's geometry and the manner in which the force is to be applied.

One machine, configurations tailored to each test

The solution’s versatility is based on the combination of three elements: the sensor, the setup, and the procedure. Sensors with different capacities allow the measurement to be adapted to the desired force levels. The accessories secure the component and apply the force according to the test being performed.

The three procedures were programmed into Califort to meet the manufacturer's needs. The Stentor II can thus be used for these various tests by adjusting its configuration for each one.

In Pictures: Tracking the Force Until It Breaks

The graph below illustrates one of the tensile tests conducted. It shows the increase in force, followed by a drop in force at the moment of failure. The video clip complements this view by showing the graph’s progression during the test.

Do you need to check the mechanical integrity of your components?

Type of load, force level, part geometry, and clamping conditions: these factors help determine a solution tailored to your application.
