Double-sided Copy Board Method:
Multilayer Board Copy Method:
In fact, the four-sided board copying is repeated copying two double-sided boards, and the sixth layer is repeated copying three double-sided boards. The reason why the multi-sided board is daunting is that the internal wiring cannot be seen. How to see the inner layer of a precision multi-sided board?Layering.
There are many methods of layering, such as potion corrosion, tool stripping, etc., but it is easy to separate the layers and lose data. From experience, sanding is the most accurate.
After copying the top and bottom layers of the PCB, sandpaper is usually used to polish the surface layer to show the inner layer; sandpaper is ordinary sandpaper sold in hardware stores. Generally, the PCB is laid flat, and then press the sandpaper and rub evenly on the PCB ( If the board is very small, you can also spread the sandpaper flat, press the PCB with one finger and rub it on the sandpaper). The main point is to pave it flat so that it can be ground evenly.
The silk screen and green oil are generally wiped off, and the copper wire and copper skin should be wiped a few times. Generally speaking, the Bluetooth board can be wiped in a few minutes, and the memory stick will take about ten minutes. Of course, if you have more energy, it will take less time. If you have less energy, it will take more time.
Summary: Understand the above-mentioned six methods of pcb imitation, double-sided and multi-sided board copying methods, these methods introduced above to actually operate correctly, get the same printed circuit board as the original printed circuit board, this time it should be carried out test. If its prototype and performance are exactly the same as the original one.
