Hello. I would like to know the difference (if any) between water soluble flux and test socket cleaners (e.g. for Burn-In Board test sockets). As far as I know, they both remove oxides (tin & copper) with an activator, solvent and surfactants. Tha

I'm not familiar with any "test socket cleaners", but I will tell you that water soluble flux is designed for a soldering application so it requires heat to activate. Not sure how effective it would be at removing oxides at room temperature. Second

Thank you caurbach. I'm actually not sure if they are cleaners specifically for test sockets or they are just generic PCB cleaners.

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

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

Sure, the formulation and purpose of a soldering flux and a socket cleaner are basically the same. Off the top of my head, differences are: * Activation temperature: soldering flux [~200*C], socket cleaner [~120*F] * Compatibility with some solder

The environment of a burn-in chamber is specific. That environment has a fairly well defined affect on the metal contacts of a burn-in socket. Test socket cleaners are tailored for those specific requirements. Look at the MSDS for the WS flux and th
