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

Here are the scenarios: *No-Clean Flux & Foam Fluxer: alcohol is used as a thinner (for titration purposes) if your flux is alcohol-based *No-Clean Flux & Spray Fluxer: alchol is used only as a cleaning agent for your sprayhead.

What flux are you using? We use a low-solids No-Clean water-based flux. Maybe some of what you are seeing is not residue from the flux but is from reaction with the solder mask.

Good morning, What is considered "high frequency" ,.i.e. Mhz,GHz,etc., when we talk about possible issues with NO-clean flux residues and product's application? I appreciate your help on this... Have a good one! George

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

Casimir This is not an easy subject. How did you process the test pieces? Was the flux used correctly at the required and recommended level? Did it see the wave properly? I am not an advocate of no-clean but we do have customers who coat over no-cl

Dave You are so right about that point. I still use some cost models we ran up some 5 years ago. I took one to a customer and showed them that they could make $400K more PROFIT PER YEAR running OA v No-Clean. Their response? Well, we don't believe

ROSE testing a post-reflow assembly which has been reflowed using no-clean flux may not yield information that is helpful. No-clean flux technology works by encapsulating the flux's activators and other chemical constitutes that would be harmful if l

Hi all Pls. help advise. Our board use RMA solder paste (Pb-free Sn96.5/Ag3.0/Cu0.5). Can we use No-clean paste flux (Delta 670S1) in rework process? If it can not be used, why?. Thanks very much for your advice. Surachai

Hi, I could like to find out what are the things need to look out if I'm doing a new SMT solder paste ( water soluble & no-clean ) evaluation. And also flux ( spray type ) for wave-solder ( water soluble & no-clean ). Appreciate for all the input..
