How much do you know about PCB copy board common sense?

With the rapid development of my country's PCB industry in the past ten years, there is still a lot of room for development in the future. Many domestic manufacturers specializing in PCB proofing can not only make boards, but also copy boards. The concept of PCB copy boards first emerged in the 1980s. After decades of continuous development, PCB copy boards have become a global service provider. The development of the electronics industry and the global industry of domestic core technology research, and all kinds of copy board companies at home and abroad are also countless.

The so-called PCB copy board can also be called PCB clone, that is, under the premise that there are already physical objects of electronic products and circuit boards, reverse R&D techniques are used to reversely analyze the circuit boards, and the original product PCB files and bill of materials (BOM) documents, schematic documents and other technical documents and PCB silk-screen production documents are restored 1:1, and then these technical documents and production documents are used for PCB manufacturing, component welding, flying probe testing, circuit board debugging, and completion A complete copy of the original circuit board template.

How to copy the board for the four-layer board? In fact, it is enough to copy two double-layer boards repeatedly, and so on, the sixth layer is to copy three double-sided boards repeatedly. The more multilayered board, the less it is possible to see the internal wiring, then a precise multi-layer board How do we see the appearance of the inner layer of the board? First, we have to layer first. There are many methods of layering, such as potion corrosion, tool stripping, etc., but these methods have certain risks. If you don’t pay attention, just It will cause damage to the circuit. Therefore, the most commonly used method is to polish the top and bottom layers of the PCB. After we finish copying the top and bottom layers of the PCB, use the sandpaper to remove the surface layer to display the inner layer. Generally, the PCB is laid flat, and then the sandpaper is pressed. Rub evenly on the PCB. Special attention should be paid to paving the circuit board so that it can be ground evenly.

PCB copy board contains huge energy. This energy is not only for copy board design service companies, but also for the entire electronic product market and information technology industry, because it objectively promotes the technical capabilities of Chinese companies and thoroughly Break the technical barriers. The PCB factory has always adhered to the exquisite technical force, sophisticated production equipment, perfect testing methods, product quality higher than the industry standard, and warm and thoughtful service, which has won praise and welcome from global merchants and users.
