When you inspect PCB board, you must pay attention to some details. In order to be more prepared to ensure PCB board’s quality, we should pay attention to the following 9 tips. It is strictly forbidden to use grounded test equipment to touch the live TV, audio, video and other equipment of the bottom plate to test …
With the rapid development of mobile phone, electronics and communication industry, it also promotes the continuous growth and rapid growth of circuit board proofing industry. People have higher and higher requirements for the number of layers, weight, precision, material, color and reliability of components. Due to the fierce price competition in the market, the cost …
Short circuit of PCB is a very common problem in the production of PCB. There are generally two cases of short circuit, one is that PCB has reached a certain service life. The second situation is that the inspection work in PCB production is not in place. However, these small mistakes in the production of …
Whether amateur or professional technician, to learn to build and maintain their own projects and systems, we must understand how PCB works and can repair them in case of PCB failure. So, how to repair PCB? How can I master this skill? What is the benefit of mastering this skill for your career? Why do …
