Pcb circuit board how to function test
Pcb circuit board in the whole manufacturing process, you need to understand its circuit diagram design, production before and after the file editing and modification, the only way to produce the corresponding open mold data, drilling data, to meet the production process The Once the pcb circuit board is successfully generated, the need to pay attention to a lot of things. For example, pcb circuit board test is also we need to pay attention to the matter, the following detailed description of the following:
As the pcb circuit board has a more intensive features, higher features, so throughout the testing process, it will have an unprecedented challenge. So at this time in this environment need to do a serious design, to understand some of the well-thought test methods with the appropriate tools is essential. So well prepared and careful screening of the matter can be achieved from the true sense of the multiplier effect.
Today, pcb circuit board function test becomes more and more important. But it is the same with the online test, its technology development with the pcb circuit board design will be subject to some restrictions, which can go to overcome some difficulties. Only in the era of constant replacement, the test method is also facing one after another challenge. After all, pcb circuit board is also gradually changing the structure more compact, speed up the pace and so on, so verify the overall functionality of the product, maintenance of calibration information is the test link can not be ignored.
Pcb circuit board in the testing process, the implementation of the test by the budget, production and product testing (UUT) design and other factors, and it is the last one in the end to measure what the greatest impact, the budget and production will be Limit the test of the project. In order to get the test to the highest possible fault coverage, the design stage must pay attention to the choice of components and PCB layout, unfortunately the actual situation is not always the case, eager to enter the market and intense development often disrupts your Wishful thinking.
Here's a preliminary analysis of how to handle these "pcb board" restrictions. Some of the concessions that have to be made for testing may affect the design, but make the test easier and improve the test coverage. Please note that the following questions and suggestions are not intended or addressed by each test engineer. Many of these issues will affect each other, so each question should be evaluated and applied flexibly when needed.
