'Netters! Here is a theoretical question for you! Let's assume an entirely hypothetical situation where a moderate number of un-coated Assembled Circuit Cards were exposed to Ethlyene Glycol. Just for arguements sake, lets say a cooling system dumped it's coolant on the first floor above a hypothetical basement laboratory. The hypothetical Ethlyene Glycol dripped into the theoretical basement and filled up the typical anti-static bins where the hypothetical Assembled Circuit Cards are typically found. <wink> How would you clean these boards up? Would you need to? I assume there would be an impact on the SIR, but not on the ionic contamination levels. How could you tell when the boards were clean? Isn't Ethlyene Glycol a major part of many "No-Clean" solder fluxes? How could these cards be demonstrated to be fine?
