How to judge the quality of circuit board?

16 Dec 2020 -

With the rapid development of mobile phone, electronics and communication industry, the PCB industry is growing and growing rapidly. People have higher requirements for the number of layers, weight, precision, material, color and reliability of components. So how to judge the quality of circuit board when purchasing? Let's talk about it in detail. MCU development, PCB control board, PCB circuit board design, LED lighting, thermostat development

 

First, check whether the products meet their own product standards

When choosing circuit board, you can measure and test according to the products provided by the manufacturer to see if it is consistent with the thickness and specification of your products. If it meets the requirements, next, you can see the light and color of the circuit board. Usually, the external circuit board is covered with ink, if the color of the board is not bright enough, and the ink is very little, such a circuit board is absolutely not good. In addition, due to the large number of circuit board parts, if the welding is not in place, the parts will easily fall off. Therefore, when selecting, it is also necessary to see whether the weld meets the standard.

 

Second, whether the circuit board appearance and electrical connection meet the requirements

After observing the appearance of the circuit board, there are no problems in all aspects. After that, we can not take it lightly. We need to focus on whether the electrical connection meets the requirements. In order to avoid line heating, short circuit or open circuit in the process of use, we need to know the line width, wire thickness and line distance in detail to see whether they meet the requirements of their own standards.

 

Third, various tests

In order to be able to use high-quality circuit boards, we need to test all aspects of them. Of course, before that, we need to know what advantages the high-quality circuit boards have, such as whether the mechanical properties of the circuit board surface meet the installation requirements, and so on.

 

To sum up, when purchasing circuit boards, as long as you can firmly grasp the above points, you can not only distinguish from its appearance, but also know its performance and structure, then it is relatively simple to find a suitable circuit board for your own use.
