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

I'm not aware of a standard for the storage conditions of assemble circuit boards. Here's what I'd do: * Protect them from damage * Store them vertically * Constant Temperature 22°C +/- 3°C * Humidity Control 45% To 65% R.H.

Hi Dave, we tried the net search. anything close to the part no. draws only the "reliability data sheets" with a small print ref to JSTD-020 standards. this implies a 215deg-C @3 cycles of Reflow Oven processing. however as this can be claimed as a

Ashok: I believe J-STD-033 was released in the past year. A-610B is much older than that maybe 5 years. A-610C, �3.4.1 references J-STD-033. Ta. Dave F

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?

Not aware of anyone that builds anything like the C3 selective extraction system. I know there is a move to develope and IPC test method for this process, but it's not there yet.
