Reverse Engineering

Another service we offer at Kejie PCB is Printed Circuit Board Reverse Engineering.
We can take your sample, including components, and completely reverse engineer it.
We create all the data you need to make duplicates.
We can even reverse engineer boards that include programmed IC’s, custom parts, and obsolete parts.


To begin, we identify every component on the board. We then create a rough bill of material for the project. The board is completely and carefully photographed. A photocopy of the board is blown up and mounted. Each component is removed and glued to its location on the photocopy. The bill of material is refined as values are measured for resistors and capacitors. When the bill of material is completed, parts are procured, the board is scanned on a calibrated scanner in order to recreate the trace pattern, and the new bare boards are created. A sample completed assembly is sent to the customer to insure proper function prior to completing the project. This becomes a ‘golden board’ from which all others are duplicated.
