20 years of PCB experice and specilize in protype and small volume
Printed circuit boards are the providers of electrical connections for electronic components. It has been developed for more than 100 years; its design is mainly layout design; the main advantage of using the circuit board is that it greatly reduces wiring and assembly errors, and improves the automation level and production labor rate. According to the number of circuit board layers, it can be divided into single-sided PCB board, double-sided PCB board, four-layer PCB board, six-layer PCB board and other multi-layer circuit boards. There are many types of PCB boards in our company, including Double Sided PCB Wholesale, 6-layer and multi-layer PCB board supply. Since the printed circuit board is not a general terminal product, the definition of the name is slightly confusing. For example, the motherboard for the personal computer is called the motherboard, and cannot be directly called the circuit board. Although there is a circuit board in the motherboard, It's not the same, so when you evaluate the industry, you can't say the same thing. For example, because the integrated circuit parts are mounted on the circuit board, the news media called him an IC board, but in essence he is not equivalent to a printed circuit board. We usually say that printed circuit boards refer to bare boards, that is, boards without components.
Double-Sided Rigid-Flex PCB
What are the layers of PCB printed circuit boards, and what are the meanings and functions of each layer? We give the following information as a PCB Board For Industrial Control Supplier for your reference:
The signal layer is mainly used to arrange the wires on the printed circuit board. Protel99SE provides 32 signal layers, including Top layer, Bottom layer and 30 MidLayer.
2.Internal plane layer (internal power / ground plane)
The Protel99SE provides 16 internal power plane/ground planes. This type of layer is used only for multi-layer boards and is mainly used to arrange power and ground lines. We call double-layer, four-layer, and six-layer boards, which generally refer to the number of signal layers and internal power/ground layers.
The Protel99SE provides 16 mechanical layers that are typically used to set the board's form factor, data marks, alignment marks, assembly instructions, and other mechanical information. This information varies depending on the requirements of the design company or PCB manufacturer. Execute the menu command Design|Mechanical Layer to set up more mechanical layers for the printed circuit board. In addition, the mechanical layer can be attached to other layers to output the display together.
4.Solder mask layer (solder mask)
Apply a layer of paint, such as a solder mask, to each part of the pad to prevent tin on these areas. The solder mask is used to match the pads during the design process and is automatically generated. The Protel99SE offers two solder masks, Top Solder (top layer) and Bottom Solder (bottom layer).
5.Paste mask layer
It functions similarly to the solder mask, except for the pad of the corresponding surface-mount component when the machine is soldered. Protel99SE offers two solder paste layers, Top Paste (top layer) and Bottom Paste (bottom layer).
We are manufacturers of industrial control boards. We understand all kinds of information about PCB boards. At the same time, we have a wide range of products, which can not only produce a large number of PCB boards, but also provide Low volume PCB Manufacture services. If you have such requirements, you can Contact us and we will be happy to help you.
