What are the classifications of automated test fixtures?

The so-called automated test fixture is a fixture/equipment that is controlled by computer software and performs tests on devices, PCBA, subsystems, and overall systems. The central module part can be adjusted and replaced to achieve the universality of different tested products, which can reduce the manual and automatic completion of the test sequence, greatly improving the production efficiency and the quality and reliability of the tested products. How is the classification of automated test fixtures classified? What are the classifications of automated test fixtures?

First of all, we divide the following three kinds from the automation program:

1、Manual test, generally clamp fixture, direct input and output with probe;

2, semi-automatic testing, generally pneumatic and MCU, can do some exploration and measurement equipment;

3, automatic testing, do not participate in any manual test of functional testing.

Then divide the structure:
1. MCU type functional tester, mainly based on the functional test fixture controlled by the single-chip microcomputer;

2, PLC class function tester, mainly for industrial control, only the timing of the product to do functional testing;

3, the computer function tester, general computer software control and read data to test product performance.

Finally, the following sections are distinguished from the control module:
1, controller, do a comprehensive control of the brain, mainly computers, microcontrollers, PLC, etc.;

2, input, output switching module, IOport;

3, signal source and measurement module;

4, power supply;

5, data reports and data statistics;

6, man-machine interface.

The classification of automated test fixtures is basically based on the above classification. It is necessary to use automated test fixtures before the products enter the market. It can make the test data more accurate, improve the test speed of products, and save labor costs.
