No-clean flux and high frequency?

Electronics Forum | Mon Feb 05 09:42:21 EST 2007 | George

Hello everybody, What is considered "high frequency" 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

Water wash flux and cleaning

Electronics Forum | Mon Jun 19 07:59:01 EDT 2017 | emeto

Hello, I am planning to use a water wash flux. As this is new to me, would you guys share what should I be aware of? I know cleaning PCBs itself presents issues. If you can share your experience so I can prepare better, it would be great.

Your best bet is to do a decision making matrix. Each company has so many different criteria�s it's hard to pick out which one might be important to yours. Simply pick out your top 5 paste manufactures. Next decide what your "Eliminators" are - th

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

Re: Ionic testing and No-Clean flux

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 �

Contamination/process issues of SMT and wave soldered pcb's

Hi, undercured solder resists may be a defect people have seen so far. Some of the probles arising is blistering as well as reaction with wave solder flux that may lead to some kind bad gel like formations. Gels the idea would be to reflow the ba

Hey guys, Anybody having trouble with increased false contact issues in ICT after switching from lead to lead free? Our test guys keep trying to imply that the flux residues are a problem (we're using Alpha EF2202), but as the soldering process eng

I agree! I am using a SAC305 no clean from Alpha. I have noticed that even hand probing with volt meter leads requires me to press very hard on the pads to bust through the flux residue.

Yes we do have a problem with this. We have by now investigate numerous lead/RoHS PCBA:s The RoHS boards are by far the most difficult one's to probe and test. Our people at the "test area" including Flying Probe and ICT they spend a lot of time to t

in all actuality, you are both right. Alpha metals does have the toughest/hardest noclean residue that I have seen. When changing to no-clean FLUX you should run different probes. So back to square one. You're both right so who's gonna win?
