Before leaving the manufacturer, the bare PCB (printed circuit board) and PCB assembly (PCBA) must pass the electrical test to ensure that the circuit board has high performance and high reliability in the final product. Conduct electrical tests to find electrical and circuit problems, such as short circuits, open circuits, resistance, capacitance, etc. All these …
Aluminum PCB (metal base heat dissipation plate (including aluminum substrate, copper substrate and iron substrate)) is a low alloyed Al Mg Si high plastic alloy plate. It has good thermal conductivity, electrical insulation and machining performance. Compared with traditional FR-4, aluminum pcb adopts the same thickness and line width, it can carry higher current, and …
The biggest difference between flexible electronic printing and printed circuit board is that the current carrying capacity of wires is different. The heat dissipation capacity of flexible electronic printing is relatively poor, so the current carrying capacity it can bear is relatively small; The heat dissipation capacity of printed circuit board is relatively strong, and …

Regarding the design of the PCB circuit board, do you know what the design process is there? 1. Preliminary Preparation Preliminary preparation includes preparing component libraries and schematic diagrams. Before proceeding with PCB design, we must first prepare the schematic SCH component library and PCB component packaging library. PCB component package library is best established …

The multi-layer circuit board is called multi-layer PCB only if it is two or more layers. The multi-layer board is more than two layers, such as 4 layers, 6 layers, 8 layers, etc. Of course, there are also three or five layers of circuit design, also known as multi-layer PCB circuit board. The conductive wiring diagram of more than …

Many engineers still have such problems after debugging PCB. Today, we summarize the steps of debugging. We can do this in this way and save many troubles. Step 1: Detection Before Power On After a circuit board is welded, while checking whether the circuit board can work normally, it is not usually directly supplied with power to …

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 …
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 …
