For a newly designed circuit board, there are some difficulties in debugging, especially when the board is large and there are many components. But if we master a set of reasonable debugging methods, debugging PCB will get twice the result with half the effort. PCB Debugging Steps 1. Observe PCB Board For the new PCB …
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 …
PCB design process is divided into six steps: network table input, rule setting, component layout, wiring, inspection, review and output. Last article we introduce the first 5 steps. Here we will introduce the last step: design output. Design Output PCB design can be output to printer or output photo drawing file. The printer can print …
PCB design process is divided into six steps: network table input, rule setting, component layout, wiring, inspection, review and output. Here will will introduce the first 5 steps. Input of Network Table There are two ways to input the network table. One is to use the OLE PowerPCB Connection function of PowerLogic, select Send Netlist …

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 …
