There are three simple ways to do this. The first is to characterize your material set using SIR. Next, if there's a problem, you can do ion chroma- tography to find out what has caused the issue, but only if there's a problem with your SIR results. Finally, you can then use the ionic contamination tes- ter (or ROSE test, as it's better known) as the process control tool. That's a big thing we are trying to help people understand about the ROSE tester. It is not a cleanliness tester; it's a process control tool. When you get a golden board and put it in the ionic contamination tes- ter, that will give you a new num- ber. That number could be 1µg, 3µg, or 4µg, it doesn't matter. As long as it's proven and it works in SIR, then you've got the number that you can use on the shop floor. The quick test on the shop floor—pass, fail requires a number, your objective data—that is born out of doing the SIR work to characterize your material set. Neves: A lot of the tests that are out there have been just window dress- ings, check-the-box, plausible deni- ability should something go wrong. Of course, my lab did a lot of that because the industry demanded it. But I remember thinking that people were throwing away their money in terms of what was meaningful. I don't know that there was another choice at that time, but now there is. This process of finding Objective Evidence gives you the ability to watch and con- trol your process and prevent things from happening. If you failed the old
