What are the Techniques of PCB Cloning

Concept of PCB clone

PCB clone is the process of obtaining the schematic diagram and the PCB diagram from the original PCB board. The purpose is for later development. Later development includes installation of components, deep testing, modification of circuits, etc. Because it does not belong to the category of PCB clone and is related to it, it is only introduced and will not be detailed.

The process of PCB clone

1. Remove the devices on the original board.
2. Scan the original board to get graphic files.
3. Grind off the surface layer to get the middle layer.
4. Scan the middle layer to get the graphic file.
5. Repeat steps 2-4 until all layers are processed.

6. Use the special PCB clone software to convert the graphic file into an electrical relationship file --PCB diagram. With the right software, the designer only needs to trace the graph once.

7. Check and complete the design.

PCB clone skills

PCB clone, especially the copy of multi-layer PCB board, is a time-consuming and laborious work. It involves a lot of repetitive labor. The designer must have enough patience and care, otherwise it is very easy to produce errors. The key to clone PCB design is to use appropriate software instead of manual repetitive work, which is time-saving and accurate.

1. Scanner must be used in the process of PCB clone.

Many designers are used to drawing lines directly on PCB design systems such as PROTEL, PADSOR or CAD. This habit is very bad. The graphics file obtained by scanning is not only the basis of converting into PCB file, but also the basis of later inspection. The use of scanners can greatly reduce the difficulty and intensity of labor. It is no exaggeration to say that if the scanner can be fully utilized, PCB clone can be completed even by people with no design experience.

2. Single direction grinding plate.

Some designers in order to pursue speed, choose bidirectional grinding plate. (that is, from the front and back surface to the middle layer to wear off the plate). This is very wrong. Because the two-way grinding plate is very easy to wear, causing damage to other layers, the result can be imagined. The outer layer of the PCB board is the hardest due to the process and copper foil, pad and other reasons, and the middle layer is the softest. So to the most middle layer, the problem is more serious, often can not be polished. In addition, each manufacturer produced PCB board material, hardness, elasticity are not the same, it is difficult to accurately grind.

3. Choose excellent conversion PCB clone software.

The key of the whole work is to convert the graphic files obtained by scanning into PCB files. You have a good conversion file. Designers only need to "follow the tiger", the graphics can be traced to complete the work. Here I recommend EDA2000, it's really convenient.
