We vote for: IPC-TM-650 2.3.25.1, solvent: 80�C, extract time: 60 minutes, hold time: 30 minutes or until room temperature. Listen, it really doesn't matter which method you decide to use. IPC-TM-650 2.3.25 is a process control method. It's more imp

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

the vary results might be from following issues.. the co2 during the test the during time for this testing... the manual testing method is conductivity measurement however the bulk contamination tester like omega is resistance measurement (i remem

The most common method is a R.O.S.E tester. They have been around for 30 years and are an industry standard for ionic contamination (flux and other residues) testing. Manufacturers include: Zero Ion www.aqueoustech.com Omegameter / Ionagraph http:/

| We understand that testing for ionic contamination and surface insulation resistance measure different properties. We assemble printed circuit boards for other companies. We will not get combs on 90% of the boards that we assemble. | We have no c

Hi -K We are a manufacturer of ionic contamination testers (not yours). In most cases, automatic mode is appropriate. In some instances however, you may need extra time to �release� entrapped contamination from the sample. Automatic mode is not a

Your Ionograph and Zero-ion Values are set by you. There is no raw pass of fail criteria only the limits you set up. Ionograph is great for bare board resistivity (salt) test just as a pass fail for incoming inspection but this is all per your facto
