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

Both are equally efficient process control tools. Neither is particularly effective in testing ionic contamination. The best way to sell your customer on allowing you to do this is to show them that you understand the WHOLE process and are able

Hi davef, Will the ion chromatography be able to quantify then identify where and what the contaminant is? Is this a destructive type of testing or the PCB will remain intact right after the test? thanks for the inputs. dreamy

Hi, What's the acceptable criteria for Ion Chromatography Testing? I found a test lab but they said we have to define what is pass or failed. Can anyone guide me to the right document either IPC or MIL Std? thanks,

There is also a new cleanliness tester that looks at localized areas to provide a cleanliness reading and can extract a sample to use in ion chromatography testing. You can find out about it here: http://www.residues.com/C3.html

Hi Ken, You're right - they're not doing anything smart, they are just using a rechargable battery pack. It's not even the latest or most suitable technology for the application (Li-ion has far better temperature characteristics & far high capacity

Distilled water normally removes ions as well as dissolved solids (non-volatiles). Deionized water has been stipped of ionic species, but non-ionic organics are left behind.

Remember, deionized water is very corosive. If the water is too deionized, 10 mega ohm, it will leach the ions from exposed metals. I had a stencil cleaner where the welds completely dissolved. The stainless steel tank was fine but the welds were
