Nowadays, electronic chips play an important role in the field of electrification in our country. with the changes of our market, electronic components play an important role in life.
PCB multilayer circuit board is the basic component of electronic components. Nowadays, the use of PCB multilayer circuit boards has become a popular trend in the market. With the development of the industry, the ability of many businessmen to develop
PCB multilayer circuit boards has become more prominent. Adjusting the components of
PCB multilayer circuit boards to make it have a better effect. The following chapters will analyze more PCBs for you. What are the basic components of PCB?
1, internal power supply layer
The signal layer and the inner transformer in the PCB multilayer circuit board are added to each other through the aperture to achieve better electronic operation capability, while the inner power layer is the unique accessory in the PCB multilayer circuit board. Under the use of this inner power layer, the various classes can be transformed into better connections.
2. Signal level
PCB multilayer circuit boards to achieve information exchange is the most important is to have three major signal layers, and these signals are wiring and welding, in the PCB multilayer circuit boards in the placement of components and signal lines, so that the PCB multilayer circuit boards to achieve normal information service functions. Under the use of this information layer, the PCB multi-layer circuit boards show good information exchange ability, and the use of this PCB multi-layer circuit boards can achieve better electronic control capabilities.
3. Mechanical layer
A way of Mechanical City in PCB multi-layer circuit boards. Parts with indicative information about plate making and preparation methods can draw the border of PCB and place better processing technology in the use of multi-layer circuit boards to realize concise page planning. This kind of mechanical layer also makes the connection of process clearer and clearer.The production of circuit boards is a relatively complex process, which basically requires corresponding equipment to process in each production link, and requires a lot of energy and cost. A good PCB board has a lot to do with the production equipment of PCB factory. Especially some high-difficulty PCB boards require higher equipment.
Two. In the production process of PCB, the following production facilities are required:
1. Engineering production - photo printer, film exposure machine.
2, open the material - the machine, baking oven oven.
3. Lamination - browning production line, laminator, plate mill.
4. Drilling -- CNC drilling rig
5, grinding plate - grinding machine
6. Metallized hole (PTH) -- chemical copper production line (copper wire).
7, graphics transfer - film machine, UV exposure machine or LDI
8, graphic plating - electroplating production line
9, drying (wet) film - faded film production line.
10, graphic etching etching production line.
11. Fabrication of solder mask - screen printing machine, UV exposure machine or LDI
12. Curing curing oven, tunnel furnace
13. Surface treatment ---OSP production line or chemical nickel gold wire, chemical nickel gold wire.
14, forming - punching machine or CNC gongs bed, cutting machine.
15, test --- electric measuring machine, AOI, 3DAOI.
These are the basic components of
PCB multi-layer circuit board, and this component achieves good information exchange through the connection of the circuit, which has brought good help to the industrial manufacturing and the application of machinery and equipment in our country in practical application. It is believed that with the continuous development of science and technology, the volume and scale of
PCB multilayer circuit boards will inevitably continue to shrink. The components used will be condensed together, which will make the future
PCB multilayer circuit boards show a more streamlined effect and help the industry of our country get better development.
