No, none of us can tell you what is the acceptable level of halide content or contamination in flux residue. The level of harmful residues on your product helps determine the reliability of your product. We know nothing of your product, its custome

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

Military and most commercial standards requires post-soldered boards to measure less than 10 �g/in of NaCl (14 when using an Omegameter, 20 on a Ionagraph, and 37 on a Zero-Ion). As Dave stated, 6.5 �g/in of NaCl is called out in Mil-P-55110 for ba

Casimir: Let me expand on something that I said in my response to your thread on ionic testing. Generally, no-clean people don�t use ROSE testing as part of their process control, because the ROSE test is essentially washing your board in DI/IPA �

Hi, my supplier is using the same Aqueous machine to clean the boards for 2 different customers. My product uses the chemistry of leaded clean flux meanwhile the other product uses the chemistry of lead free with no clean flux, however that product r

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

Regarding your customer suditor, it would have been nice if you said something like ... Routinely, our testing shall be less than 1.56 microgram/cm^2 NaCl equivalent ionic or ionizable flux residue, according to TM-650, Method 2.3.35 'Detection And
