Does anyone know of a less expensive technique to monitor board cleanliness (chlorides in micrograms/in2) other than omega mater - ion chromatography is costing us an arm and a leg.

New to using Ion Chromatography (IC)testing to understand cleanliness of PCB. I've been informed that one method to monitor is to use R/O/I. What is R/O/I?

Thanks for the reply. R/O/I is ROSE / Omegameter / Ionograph which is used as a baseline for Ion Chromatography.

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

edmaya33, you're correct about what J-STD-001E says, but recognize that the measure that you refer us to in not IC [Ion Chromatography]. It is modified ROSE [Resistivity of Solvent Extract] ... or whatever they call modified ROSE now-a-days

ROSE has the advantage in that it does have a specific acceptance criteria (J-STD-001), whereas the IC does not. ROSE allows the test to be run at ambient or at an elevated temp, IC requires the component/board/assembly to be "cooked" for 1 hour @ 8

Hi there - unfortunately, there are no good cleanliness specs available mainly because clealiness requirements are case sensitive - you should talk to Terry Munson at 765-457-8095 - he can definitely give you advice on Ion Chromatography, SIR, ROSE t

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
