Terminal/Pin Marking & Inseparable Assemblies

There are two more subjects we could encounter when disassemble the parts from PCB when reverse engineering a printed circuit board,  first is terminal or/and pin markings. When disassembling electrical assemblies, all terminal markings should be reviewed. If the terminal and pin location or FROM-TO data is not stamped on the wires, each end should be clearly marked and a wire-run list should be created. The photographs with all plug and terminal designations should also be clearly marked.

The second thing is inseparable assemblies, items that are not bonded, welded, or otherwise permanently joined should be treated as an inseparable assembly. Destructive disassembly may not be required. If possible, all non-destructive testing of hardware should be performed prior to destructive testing.
