I am surprised that Surface Insulation Resistance Testing is not included in this test comparison since that test is the only one which determines if the residues left on boards impact performance. To leave the one functional test out of this test program means only that different tests can extract different amounts of materials, but the question still exists - what does the presence of the material on the board mean. I would strongly suggest that the test program be rethought to include sir testing.
