We manufacture both bulk and localized ionic contamination testers. My answer is from the perspective of the cleanliness testing method. The issue with all bulk ionic contamination testers (Ionagraph, Omegameter, Zero-Ion), is that they test the en

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

Good day and thanks for your comments Mike, What did I understood from your notes� 1) ROSE test (�extracting solution�) is probably good enough (with good equipment) to penetrate the space under my micro BGA. 2) I should test 2 parallel batches of

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

Thanx Cal, how can I get the archive for year later than 2000 ? I've requested, the RR00013 but still waiting for the reply. Anyway, thanx in advance. Do people measure Bromide ? how about Chromatography test ? can it helps ? cheers
