The function of PCBA test

The function of PCBA test no matter what kind of test way, the system result basically divided into the following parts:

1.The system control center:
Is this part of the general PC, MCU, ARM of small or medium-sized central processing unit (CPU), its main function is to control the whole process of the testing process, and the judgment and record every step of the test content, test results in the end. It is the core of the whole test system the brain.
2. To control execution parts:
To control execution part is mainly composed of I/O components, it is a test process logic action induction and actuators. System through which to build all kinds of test environment, achieve the function test.
 
3. The parameter measurement:

Measurement part is mainly composed of some boards, which are used for measuring instrument. It can complete the testing process all kinds of analog or digital collection work. So sometimes we call it the data acquisition part.

4. The data processing and output part:

Each step and the final test results, is the purpose of our entire test. How to take these results and data storage, output, more convenient to our effective control over the quality of PCB assembly products, this is part of the responsibility of the data processing and output.

PCBA called live-fire circuit board. In the process of mass production of PCBA, due to the equipment and the operator of a variety of possible factors, cannot guarantee to produce PCBA all was in good taste. This requires that join at the end of the production of various test equipment and test tools, in order to make sure all the live-fire circuit board factory are in complete accord with various specifications and parameters of design. This leads to the ICT, AOI and X - Ray, a Boundary Scan, FCT has grown and other test means.
