When manufacturing a printed circuit board (PCB), you may encounter a green circuit board and a black circuit board, pcb stackup calculator which look similar, but there are some differences. This article will introduce you to these differences and help you choose the right board.
Green circuit board and black circuit board, green PCB and black PCB difference
First of all, from the appearance, the color of the green circuit board and the black circuit board are different. 1 oz vs 2 oz The green board has a typical transparent green appearance, while the blackboard is dark black. This means that if you want to print a pattern on a printed circuit board, a green board may be better for visibility.
However, from the perspective of circuit board manufacturing, the difference between the two boards is more essential. Green boards are more common than black boards because they can usually be used for general purpose PCBS in Chinese manufacturing enterprises. These boards are used to develop electronic information products, computers, network security communication engineering equipment, medical service equipment and industrial automation equipment through a variety of technological applications, including social consumption.
On the other hand, blackboards are commonly used in high-end applications such as high-frequency circuits, high-speed signal transmission circuits, high-end computers, and other semiconductor applications. Due to the special color of black boards, they provide better signal isolation and electromagnetic interference (EMI) control.
Green circuit board and black circuit board, green PCB and black PCB difference
In addition, the manufacturing technology of the black circuit board is also different from that of the green design circuit board. The black circuit board is based on the glass fiber composite material by adding a black ink, but China's green circuit board is coated with green ink on the bare substrate. Therefore, black circuit boards can not only provide enterprises with better signal quality control, but also have higher production management costs.
In the end, which board you should choose depends entirely on your needs and target application. If your application needs better signal isolation and EMI control, or needs to be used for high-end applications, then you should choose a black board. However, if your application needs to make a regular PCB or needs better visibility, you can choose green board.
