Reverse Engineering Printed Wiring Boards

Reverse engineering PRINTED WIRING BOARD will always refers to the component arrangement, since get the bill of material from the process of reverse engineering PRINTED WIRING 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 PRINTED WIRING 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 component, so when in the process of component procurement for PRINTED WIRING BOARD manufacture after PRINTED WIRING BOARD reverse engineering, engineers can understand it well.

Modify the whole system after reverse engineering PRINTED WIRING BOARD:

1, choose the electronic components after reverse engineering PRINTED WIRING BOARD, which can help to optimize the PRINTED WIRING BOARD layout and contribute to implementation of rules of DESIGN FOR MANUFACTURE;

2, Avoid to choose those components which require the mechanical pressure after reverse engineering PRINTED WIRING BOARD, such as lead brooch, rivet, etc. except lower handling speed, it can also damage the PRINTED WIRING BOARD and it is very difficult to maintenance them;

3, use these methods to reduce the number of types of components on the PRINTED WIRING BOARD as much as possible, like use resistor array to substitute the single resistors; use a 6 pins connectors to replace the two triple pins connectors when reverse engineering PRINTED WIRING BOARD; if two components has quite similar value, but with different tolerance, then choose the one with higher tolerance to place onto the locations after PRINTED WIRING BOARD reverse engineering; use the screws with same size to fix the heat sink on the PRINTED WIRING BOARD;

4, the best design of PRINTED WIRING BOARD is the one which can make installation on site when reverse engineering PRINTED WIRING BOARD, such as install a switch on domestic made PRINTED WIRING BOARD into a exported made one, or use the jumper to change the model from one to another.
