Part Controlling in PCB Disassembly

PCB Disassembly process is extremely important for PCB Reverse Engineering. During PCB disassembly, each piece of part or component (bagged and tagged) should be identified to facilitate control of parts. Each piece of part or component should be examined to determine any markings which could identify the actual manufacturer, i.e., trademark, FSCM (federal supply code for manufacturers) number, manufacturer’s name, part number, patent mark, mold mark, manufacturing date code, etc.

Each piece of part or component should be placed on an blank white A4 Paper one by one by orderly and use transparent adhesive tape to attach each one of them on it, beside them, marking or even specification should be written to specify its value or their designators on the corresponding place of PCB which applied for reverse engineering.

Where lubricant is applied, look for markings on the grease fittings which may indicate the lube oil requirements. Samples of the grease or lubricant should be taken for future identification prior cleaning the disassembled parts.
