Mechanical Environment Reliability Test

Matexcel can provide mechanical environment reliability test for your products. Our test content is comprehensive and extensive, mainly including: tensile test, drop test, mechanical impact test, vibration test, bending test, insertion force test, three comprehensive test. We can also customize your own experimental protocol for you according to your requirements.

• Tensile test: tensile test refers to a test method for measuring the characteristics of materials under axial tensile load. The data obtained from the tensile test can be used to determine the elastic limit, elongation, elastic modulus, proportional limit, area reduction, tensile strength, yield point, yield strength and other tensile properties of the material.

• Drop test: when the packaging box, packaging pulley, and product fall from a certain height and come into contact with the ground of the drop area, they will be subjected to a large impulse, which will cause the transient vibration of the packaging box, packaging pulley, and product, and a certain displacement Large stress and strain are generated in the packaging box, packaging pulley, and product, and the packaging box, packaging pulley, and product with weak drop resistance will be damaged or reduced in performance due to the drop. After the test, the packaging box, packaging pulley, and product appearance can be tested to determine the strength of the packaging box, packaging pulley, and product.

• Mechanical shock test: used to examine the adaptability and reliability of components subjected to sudden external shocks. In order to confirm the structural strength and reliability of the product, the impact test has a good screening effect. Impact can cause desoldering, poor contact, and poor working characteristics. This experiment generally uses a mechanical impact test stand.

• Vibration test: when the test sample is excited by a long-term vibration of a certain specified acceleration and frequency range from the outside, the test sample will be in this vibration state, and the stress on it will repeat this stress state of vibration repeatedly, so Stress fatigue is caused, and fatigue strength decreases, and fatigue damage will occur. After testing the appearance, electrical properties or internal structure of the sample, the ability of the sample to resist vibration can be judged.

• Bending test: the test to determine the mechanical properties of materials when they are subjected to bending loads is one of the basic methods for testing the mechanical properties of materials. The bending test is mainly used to measure the flexural strength of brittle and low plastic materials (such as cast iron, high carbon steel, tool steel, etc.) and can reflect the deflection of the plastic index. Bending test can also be used to check the surface quality of materials. The bending test is carried out on the universal material machine. There are two loading methods: three-point bending and four-point bending

• The insertion force test: it refers to the force required to insert and pull out the electronic connectors at both ends of the mating male and female. The insertion force is an important mechanical property and parameter of the connector. Its size affects the feel of the connector and its connection. The internal design structure of the device.
Application range:
1. Single-hole connector insertion and removal test
2. Connector row insertion test
3. Connector plug life test

Three comprehensive test: temperature and vibration test (two comprehensive tests: vibration-temperature, temperature-humidity, vibration-humidity, three comprehensive tests: vibration-temperature-humidity) is a combination of a constant temperature and humidity test box or a rapid temperature rise and fall test box and a vibration table The test conditions achieved by the completed test equipment. Three comprehensive tests are enough to simultaneously carry out the influence of temperature, humidity and vibration on the product.

The application of a separate environmental stress on the product can excite the failure of the product, then the application of three different environmental stresses on the product can easily achieve a 3-5 times acceleration effect. At the same time, by synthesizing different environmental stresses, failures that cannot occur when individual stresses are applied can also be stimulated.
