Could anyone give me some suggestions on where I could get information on Surface Leakage Resistance Testing. We are contract manufacturers and we have a new customer requirement that calls for the printed circuit boards to have a Surface Leakage Resistance greater that 5 X (10 to the 7th) Ohms at 90% relative humidity.
