Heated Solvents

Heated Solvents

As counterfeiters developed advanced techniques to hide the evidences of resurfacing, some of the resurfaced components may be resistant to Acetone or Alcohol solution swab.

A more advanced testing procedure is using heated solvents at 105° C, such as DynaSolve 750 / 711, and 1-Methyl 2-pyrrolidone.

The electronic component is placed half way into the solvent for 45 minutes.

The heated solvents remove any resurfacing material, revealing the original surface beneath.

This Test can expose sanding scratches, blacktopping material,

and the original marking.
