Hi All, As a result of equipment damage I have a problem with a cleanliness of printed circuit assemblies. One whole production batch was polluted by ionic residues because a large amount of hard water had been penetrated in the water-supply system

I'm looking for test labs in Taiwan that are capable of performing ionic contamination testing on small to medium sized SMT boards. I'm interested in both ion chromatography and ROSE test methodologies. Is anyone aware of any labs performing contami

Aqueous Technologies manufactures the Zero-Ion ionic contamination tester. The Zero-Ion utilizes dynamic-based technology and has been assigned the highest equivalency value by the NAWC. It is among the most sensitive of all of the military-approved

since IPC-J-STD-001 RevH obsoleted the 1.56ug/cm2 UCL of ionic contamination tester in testing using ROSE test, how do you define the acceptable limit per PCB assembly? thanks

If No-Clean flux does not need to be cleaned, then why do I get readings of up to 27(ug NaCl/sq in) on boards that are not washed, up to 23.4(ug NaCl/sq in) on boards washed with DI water only and from 1.2 to 10.1(ug NaCl/sq in) on boards washed with

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 �

Graham: Maybe a twist on your comments, I don't believe that people understand the true cost of using no-clean. Dave

Graham, Please describe the term OA? I have never heard of that acronym. Thanks, Brian E. Steelglove

Brian: SMTnet has a "Terms & Definitions" section in the "Library." OA Flux. Flux, Organic Acid. A water soluble flux. Good luck Dave F

How does no-clean flux residues on a PCB assembly impact the ROSE testing? Does no-clean flux residues on the PCBA dissolve in solution of ROSE tester and increase ionic contaminants level in terms of NaCl per surface area? Is ROSE tester solution (a
