North Shore Components utilizes three methods of resistance to solvents testing to determine the authenticity of electronic components. This testing method is able to remove painted markings that are commonly made by counterfeiters, without altering or damaging industry-standard etching.
This marking test is an industry accepted marking permanency test. The three parts mineral spirits and one part IPA solution checks for solvent soluble remarking of a component’s logo, part number, date code, etc.
Parts are blacktopped to cover evidence of tampering or to give a new surface to allow remarking of a device. Acetone checks for non-epoxy blacktopping that covers original component surfaces.
If the solvent testing reveals no failing but the parts are still suspect, a scrape test can be performed. Lightly scrape the components surface with a sharp blade to see if a clear coating has been applied to restore surface smoothness and conceal sanding. Peeling or flaking material indicates possible blacktopping with coatings not affected by acetone.
