TechNetters, Thanks for your responses to my posting about BGA's. I am sharing the info received with my fellow employees and they are impressed. Here is another request: Does anyone have info on ESD control for class 100 clean rooms. We are ok as long as the humidity stays up, but when it drops so does the product yeild. We tried a few compromises, but contamination levels are very critical to the product. Has any one seen any contamination free booties with sole grounding capability?
