What Is PCB Flying Probe Test?
Jan 18,2025
PCB flying probe test is an electronic circuit test method is mainly used to test the printed circuit board (PCB) on the electronic components and their connection performance. What is the flying probe test? Flying probe testing (FPT) uses four to eight independently controlled probes that are programmed to move through the air and access various component pins on a PCB one by one. During testing,...

Advantages And Disadvantages Of Thick Copper PCB
Apr 15,2025
Thick copper sheet is a commonly used electronic base material in modern electronic circuits and power transmission, among other areas. Typically, the copper foil thickness of standard circuit boards ranges from 1oz (~35μm) to 2oz (~70μm), whereas the copper foil thickness of thick copper boards is usually more than 2oz, typically up to 3oz (~105μm) or higher. It has a thicker layer of copper comp...
