How to judge the quality of Circuit Board?
With the rapid development of mobile phone, electronic and Communication Industries, the PCB circuit board industry has been growing and growing rapidly, people are demanding more and more for the layer number, weight, precision, material, color and reliability of components. So how to judge the quality of the Circuit Board when making selection and purchase? The following is by Shenzhen Circuit Board manufacturers-SUNSOAR Circuit Board manufacturers with you detailed introduction. First, in the purchase of circuit board, you can according to their manufacturers to provide products for measurement testing, to see whether with their own product thickness and specifications. If that's the case, then you can look at the light and color of the circuit board. Usually love, the External Circuit Board is covered with ink, if the board color is not bright enough, and ink is very little, this circuit board is definitely not good. In addition, because the circuit board parts are more, if the welding is not in place, the parts will be easy to fall off the case, so in the selection, it is necessary to see whether the weld is up to standard. Second, after observing the appearance of the circuit board, all aspects are no problem, after we still can not take it lightly, but also need to focus on the electrical connection to see if it meets the requirements. In order to avoid heating, short circuit or open circuit, we need to know the line width, line thickness and line spacing in detail, to see whether they meet their requirements. Third, in order to be able to use high-quality circuit boards, we also need to test every aspect of it, of course, before we need to clear, what are the advantages of high-quality circuit boards, for example, Circuit Board surface mechanical properties meet the installation requirements, and so on, understand these, in the circuit board to judge the good or bad time will be easier. To sum up, when buying a circuit board, as long as you can firmly grasp the above points, not only from its appearance can be identified, but also to its performance and structure, so find the circuit board that suits oneself to use is still relatively simple.
