Barney, We currently have 3 Contact Systems machines, (1) C3AV and (2) C3AVXs and I can't say enough good things about the machines or the support. It has always, always been there since we started dealing with them in 1991. The Service Dept personn

We also have a Foresite C3 for spot testing for ionic contamination. I didn't use it at this spot, but used it some other spots around the PCB that showed this color change and with our C3 we were passing IPC standard for ionics. But I was wonderin

We had x-ray and optical microscopy analyses done on transformers dip soldered with Sn/Pb, SN100C3 and SN100C4 alloys using temperatures 400�C ... 450 �C, with dip times of 2..4 seconds. We found that SN100C4 is at least as good as Sn/Pb 62/38 and SN

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

thanks a lot sir davef. which is better between the two, static or dynamic? localized testing (C3) or bulk testing (Omegameter/Zero Ion)? do I really have to purchase this unit despite having an aqueous cleaner? thanks again...

Does anyone know of a SPOT cleaniness tester other than Foresite C3?
