Resources for electronic reverse engineering.

Reverse Engineering Process

Step 1: Take photos and part number of the parts from various perspective. If dimension of the part (Size, Length, Pitch) is important, record down the dimension and take photos together with a ruler or a measuring tape.

Step 2: Label and list all the components with a designator ID for all the individual components. Consolidate the quantity.

Step 3: Label all contact point on the individual component. Tablet a list of connection points to map the connections.

Step 4: Source for the components’ part-number, manufacturer, distributor (where to buy) and the price.
