Asoe, The systems you are describing are Resistivity of Solvent Extract (ROSE) Testers. These systems are available using one of two technologies, Static or Dynamic. Both systems use a calibrated test solution comprised of IPA and DI water. The t

I'm looking for test labs in Taiwan that are capable of performing ionic contamination testing on small to medium sized SMT boards. I'm interested in both ion chromatography and ROSE test methodologies. Is anyone aware of any labs performing contami

Hello We are currently cleaning stencils from both process (PbSn and lead free) in the same cleaning machine. A customer is concerned about cross contamination of lead between stencils. Is there any test kit or tool that you can suggest to test the

Hi, we are looking for a contamination tester in this stage however it looks there is 2 ways of removing residuce from PWB: static and dynamic. Both introduce their advantage to me and cause me further confusing.I am not anyone here will have tried

For more than you want to know about static and dynamic testers, read EMPF report RR000013, "An In-Depth Look at Ionic Cleanliness Testing". Request it from http://www.empf.org/index.html#

There are a lot of lead testers out there. Just google it. I personally don't think you will find anything wrong, but for the pleasure of your customers buy one and prove it. I would also check the lead on the squeegees of your stencil printers and t

When carry out the contamination test,do we measure for Chlorides on water soluble and No-clean fluxes? 1) What is the equivalent factor for machines developed to test the board cleanliness, Omega-meter vs Ionograph vs Zero-ion. 2) What values do we

Richard, With respect to the Resistivity of Solvent Extract (ROSE) test, the test solution is exceptionally aggressive. With the Zero-Ion for example, the test solution�s resistivity is 150 M-Ohms. Additionally, because test solution is made up of

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
