Are there any established acceptance criteria for contaminants based on Ion Chromatography testing? I've found some references to certain levels for some contaminants but there doesn't seem to be any industry consensus. Any feedback or reference to l

We are aware of no such standard. You need to determine the acceptable level for your product in its use environment.

It's the same like asking wether you get a gold-contaminated solder pot when soldering ENIG boards. As long as the replenishment of dross is large compared to the intake of contaminant, the contamination level will stay within acceptable levels.

Bowing to jokesters with comments about cake, in-laws that drink all their beer, musician friends, and whatnot; I'll push forward. What do yall do to manage the life and contamination level in the sponges that hand soldering operators use to clean t

Charliem, Thank you for the input. Following this logic, in case if there are no soldering issues, pad coverage and voiding levels are within acceptable limits and a gap between BTC and pad let us say 200um, this could be accepted, right? IPC-A-61

Hello, Acceptance Quality Levels vary from company to company and product to product. I would like to know what AQL's are being used in the different markets, (military, telecommunucations etc.). What is the standard level used? What

I'm currently trying to get a feel for what oxygen level I will need in my lead-free assembly process. Do I need to go with the pure vaporized liquid nitrogen, or can I get away with one of the other "on-demand" operations? All assistance gratefully
