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

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

Q1: Will the ion chromatography be able to identify and quantify the contaminant? A1: Yes, it will identify and quantify the amount of contaminant. Obviously this is very useful in troubleshooting the source of the contaminant. [The only problem fo

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 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

Mike: An omega meter has very little to do with ion chromatography. * IPC TM-650, 2.3.25B, Detection and Measurement of Ionizable Surface Contaminants is a process control method that washes boards with an isopropanol / water solution and measures

It would help to run a carbon, anion, cation, mixed-bed configuration with pure DI as the final rinse. IF your incomming water is really bad you can run a RO unit to "prepare" the water for ion exchange. Do you run omega meter or ionograph testing

Three popular methods: Resistivity of Solvent Extract (ROSE) Test Method IPC-TM-650 2.3.25: The ROSE test method is used as a process control tool to detect the presence of bulk ionics. The IPC upper limit is set at 10.0 *g/NaCl/in2. This test is p

I would suggest that it would be helpful to perform ion chromatography analysis on some of the boards that have failed your ionograph tests as well as some boards that have passed. This will tell you exactly what ionic species are present on the boa

First, SIR data is heavily dependant on the test pattern selected. Be very careful when comparing the results of resistance readings taken from different geometric patterns. Second, if yer talkin': * Bare boards, yupper. * Finished assemblies impor
