test at the bare board level consists of opens and shorts. It makes sure that all traces are hooked (connected) up to the appropriate place and they are not shorted to a non common conductor. Russ

Hi Richard My experience with R.O.S.E. testers has been positive with regard to detecting ionic contamination (even exceptionally low levels). As previously mentioned, a good R.O.S.E tester will be able to detect minuet levels of ionic contaminatio

You should specify the level of res based on the effect of the res on the end-use of the product. J-STD-001 defines cleanliness requirements for ALL flux types, including water soluble and no-clean that you mention. 1 There is no equivalency betwee

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

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

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

Does anybody knows any outside service for SIR testing. I am being question if my cleaning process is good enough and I don't have any ways of proofing it.

I agree that solderability is THE issue, but we choose not to get into that pissin' contest. [We don't like the selected test method, either.] We believe that our coating thickness spec provides: * Solderability level that we seek. * Repeatable tes
