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 …
