PCB Technical - Circuit board production process and production process

In daily life, the application of PCB is very common. The electronic products that can be touched from our side will be applied to the circuit board. Opening the inner tank of all electronic products, we finally discovered that it is such a small PCB circuit board that supports the expected work of the electronic product. However, due to the widespread use of circuit boards, consumers and businesses have higher requirements for the production materials and production processes of the circuit boards, and printed circuit boards came into being at this time. Next, let's take a look at the entire process of the printed circuit board.

Printed circuit board products

If you want to produce and this year’s printed circuit board products, you should first design the schematic diagram according to the function of the circuit. The schematic diagram is built according to the electrical functions and needs of each part. The completed design schematic diagram can perfectly reflect The main function of the PCB circuit board is to strengthen the connection between the various parts. After this step is completed, each software that has been placed must be installed so that all components have the same specifications and dimensions. After the packaging is completed, use the inspection rules to check the tightness of the device. After that, use special carbon paper to print the bcd drawings that have passed the audit through an inkjet printer, and then put the printed copper paper in a solution prepared by sulfuric acid and or hydrogen oxide. After all the ink stains are removed, clean the copper plate with clean water. Finally, it is necessary to use a drilling machine to drill holes in the circuit board where the holes need to be drilled. After all the soldering work is completed, the entire printed circuit board is re-inspected and checked. After all these tasks are completed, the printed circuit board All of the work has also been completed.

After talking about all the processes related to the production of printed circuit boards, we can clearly know that printed circuit boards are replacing the previous electronic circuit boards with cumbersome production processes. Compared with traditional electronic circuit boards, it not only shortens the production cycle of a single circuit board, but also has greater advantages in production cost and production quality.

The production process of the circuit board

Circuit boards are widely used in various electronic products. Any electronic product is inseparable from the installation and use of circuit boards. In these electronic products, we need a certain circuit board to ensure the normal operation of an electronic product.

Then our circuit boards also have some detailed classifications. According to the number of orders, circuit boards can be divided into three categories: single-sided and double-sided circuit boards and multilayer circuit boards. The threads are concentrated on one side, and on the other side, especially on the parts of the assembled PCB. From this point of view, this is just a thread, and this kind of circuit board PCB terminal is called. They are usually simple, and the manufacturing cost of the plate on one side is low, is not used, and the disadvantages of the new product are too complicated.

The extension board of the PCB double-sided board is on one side. When single-layer wiring cannot meet the needs of electronic products, double-sided circuit boards should be used. The lines in the air are put on clothes, they pass through the holes on both sides, through them, the battle line and the network connection between the two become necessary. Multilayer board refers to the printed board model. These three sequences are to stack more conductive and insulating conductive materials at a certain interval and interconnection reasons. One is wrong. The multi-layer electronic multi-round development products in the Arabic office are attracted to smaller or smaller members.

Due to the small size and complex structure of the circuit board, it is necessary to use special observation equipment to observe the circuit board. Generally, a mobile video microscope is used to observe the structure of the circuit board, but through the video microscope, the circuit-sensitive microscope can be clearly seen from the microscope. This makes it easier to design and test circuit boards.

The production process of these circuit boards is definitely not some products that can be made in a short while. They are all produced after a series of design and research, because these circuit boards are also a key means of electronic products. Therefore, the manufacturing process of PCB circuit boards is indeed a bit complicated.
