Hi GS, Just a clarification� No-clean does NOT equal no ions. It equals less ions (at best). Automatic R.O.S.E (Resistivity Of Solvent Extract) testers are commonly used to detect ionic contamination from no-clean applications. Your comment rega

edmaya33, you're correct about what J-STD-001E says, but recognize that the measure that you refer us to in not IC [Ion Chromatography]. It is modified ROSE [Resistivity of Solvent Extract] ... or whatever they call modified ROSE now-a-days

The industry standard for Resistivity of Solvent Extract (ROSE) Testing analysis is IPC-TM-650 Method 2.3.25 – Detection and Measurement of Ionizable Surface Contaminants by Resistivity of Solvent Extract (ROSE).

This is a (Resistivity of Solvent Extract (ROSE) tester. Per IPC standards, ROSE testers use a test solution comprised of 75% IPA (99% pure) and 25% DI water. -Mike Konrad Aqueous Technologies www.aqueoustech.com konrad@aqueoustech.com

An ionic contamination tester should meet industrial cleanliness specifications including MIL-STD-2000A, MIL-P-28809, J-STD-001 and Resistivity of Solvent Extract (ROSE) Test Method IPC-TM-650 2.3.25

A fairly painless method for monitoring cleanliness is Resistivity Of Solvent Extract [ROSE]. Equipment is: * Omegameter * Ionograph * Ion Chaser [Zero-Ion] Anyone who desires to use an Resistivity Of Solvent Extract tester should read EMPF repor

Jeff: Try this: ROSA. John�s spot on. I�ll add that it is a fluxless method that reduces the oxides in an aqueous solution. Another source of information is: Trench, M., Hillman, D., Lucey, G., "Environmentally Friendly Closed Loop Soldering,"

Bare board cleanliness is still primarily measured by resistivity of solvent extract (ROSE) using instruments such as Omegameters and Zero Ions. What is considered as "acceptable" cleanliness varies between specification and from company to company.

Three popular methods: Resistivity of Solvent Extract (ROSE) Test Method IPC-TM-650 2.3.25: The ROSE test method is used as a process control tool to detect the presence of bulk ionics. The IPC upper limit is set at 10.0 *g/NaCl/in2. This test is p

Resistivity Of Solvent Extract [ROSE] is a bulk ion contamination [BIC] test method. It should thought of as a process control tool used to assess ionic contaminants. Don't consider it an acceptable tool for establishing 'GO-NOGO' limits. The stan
