The discount 4 Layers PCB Board is an electronic card, usually green in color, that provides four conductive layers to route electronic signals. 4 layers PCB Board refers to the printed circuit board is made of 4 layers of glass fiber. There are four wiring layers: Top layer, bottom layer, VCC, and GND. Generally, through holes, buried holes, and blind holes are used to connect the layers. There are more buried and blind holes than double-side boards. In addition, try not to run signal track on the two layers of VCC and GND.
4 Layers PCB Board are something that makers have long known about but almost never gotten involved with. However, with the introduction of China 4 Layers PCB Board prototyping facilities around the world, and widely available CAD packages, Wholesale 4 Layers PCB Board are now within the reach of makers. But what are four-layer boards and how can they help you with your next project?
