What is a stress tester? What areas do you use? What is the principle? Application is very wide

Introduction to equipment functions and principles

In the process of measurement motherboard (such as ICT, SMT, Function Test, Assemebly, etc.)) The deformation of the plate bending is used to verify whether it has a relatively impact on BGA tin points. Users can determine whether the measured signal data measured by the “maximum main stress, minimum main stress, shear stress, corresponding angle, Diagonal, etc. can determine whether the measured signal data meets international norms and standards? Take the important reference information of the export quality of 3C products such as a server, laptop calculator, PDA, and handheld phone.

working principle:

Balance the signal of the Strain GAGES through the Bridge of the Whison Bridge, which can be converted into the corresponding voltage signal. After the analog/digital circuit inside the tester, the voltage signal can be converted to a digital signal, and then dedicated to dedicated Software to capture and analyze these signals.
