Reverse Engineering PCB Circuit Board

Reverse engineering Pcb circuit board will always refers to the component arrangement, since get the bill of material from the process of reverse engineering Pcb circuit board is very critical, in the bill of material, each one of the resistor, capacitor, inductor, crystal value, size and footprint must be measured and record, diode, triode and integrated circuit marking should be recorded properly too. Reverse engineering Pcb circuit board means not only get its layout, and circuit pattern drawing, schematic diagram, but also its part list, which has the clear description about each components, so when in the process of component procurement for Pcb circuit board manufacture after Pcb circuit board reverse engineering, engineers can understand it well.

When reverse engineering Pcb circuit board and place its components for machine insertion:

1, all of the pads of components on the Pcb circuit board should be standardized, should us e the standardized distance in the industry;

2, all of the components should be feasible for the machine insertion after Pcb circuit board reverse engineering, and engineer should be aware of the insertion machine terms and specification, and take considerable thought about the footprint of component when reverse engineering Pcb circuit board which can make it better cooperated with machine. As for those component with unusual form, footprint could be a big problem;

3, if possible, radial component should choose the axial type as much as possible, since axial components can make the insertion cost lower when reverse engineering Pcb circuit board, if the space on the Pcb circuit board is very precious, then radial component could be the first priority to choose;

4, if there are only a few of axial components, and engineer should switch of them into radial type when reverse engineering Pcb circuit board, vice versa, it can save insertion procedure;

5, when layout and reverse engineering Pcb circuit board, the consideration of component lead bending angle and the reachable range of automatic self insertion machine should be taken into consideration in the perspective of minimum electrical isolation, at the same time, at the same time, engineers should ensure there is no soldering bridge emergence on the orientation of bending leads;
