Why is it best to choose testing when making a circuit board?

In the production and manufacturing of the circuit board industry, there is a process that is optional (testing or not testing). Today, we will help customers who need to make PCB circuit boards analyze whether it is necessary to choose testing or not testing when producing circuit boards. As well as what method of testing to choose, circuit board production is divided into three major types. Today we will analyze these three major types of circuit board production.
Circuit board proofing:
Circuit board proofing refers to samples with an area within 0.6 square meters. For such circuit board proofing, we can choose flying probe testing. The cost of this kind of flying probe testing is relatively small. If it is just to test the function, we recommend that the proofing should be controlled to 0.2 Within square meters, we test it for free. Of course, there is another situation where the circuit board drawing design has been confirmed to be ok, but you just want to make a sample to test the quality of the circuit board manufacturer and the performance of the circuit board. In this case, it is OK Choose to open a test rack for testing, so that you can save the cost of a flying probe test.

Due to ceramic PCBs have high thermal conductivity and low expansion coefficient (CTE),
Ceramic circuit boards are more versatile, less complex and offer superior performance
Compared to regular PCBs.

Small batch production of circuit boards:
Small-batch production of circuit boards refers to circuit boards with an area between 0.6 square meters and 5 square meters. For this kind of small-batch circuit board production, Keyou strongly recommends that everyone open a test rack for testing. First, because boards of more than 3 square meters are used Flying probe testing takes a long time. Secondly, the cost of flying probe testing is also relatively high. Thirdly, if there is mass production later, a lot of testing costs can be saved.
Mass production of circuit boards:
Mass production of circuit boards refers to circuit boards with an area of more than 5 square meters. There is only one option for this kind of board and it is best to test it! That is to open a test rack to test the circuit board. Next, let us talk about why. Choosing to test, I think everyone knows that there are more than 10 processes in the production of circuit boards. If you don’t understand, you can check the circuit board production process. Each process must be controlled to be fully qualified to ensure the quality of the produced circuit boards, but it is always artificial. There will be some problems, and it cannot be guaranteed to be 100% qualified. Then the problems that arise need to be tested to ensure the quality. If you do not test, it may cause some cost increases, such as the increase in SMT assembly costs, the increase in component costs, etc. , so in order to ensure the qualification of our circuit board, let’s spend unnecessary waste on reasonable testing costs!

Metal core PCB is ideal for its applications that generate immense heat and have difficulty being cool down using conventional fans or other cooling methods.
