Hi Scott, Hard to tell what kind of problem you really have. I guess you need to describe your process first. What kind of process are you using. Wave solder, reflow solder, etc.. What kind of flux are you using to solder with? Vaccum? What ar

After receiving either a water soluable or low residue soldered board for rework, in a real life work environment, regardless of the quality of the documentation, we can picture it a bit confusing for troop to consistantly select the proper combinati

With allocation of components becoming a bigger and bigger problem, our company has had to purchase components from brokers. Because of this, I've found an increase of component contamination. What I mean is I have found problems with oxidation of th

We feel that we get more than our share of crusty components, but we just smile because we�re so happy ["Happy, happy" as Emeril says] that we use a nice and hot, aqueous flux. What kind of flux do you use?

Dave, We use water soluble flux. We currently do not do a solderability test on incoming components, I'm thinking that this is going to be a "must do" with these components. Larry

boards greater than this spec. can cause latent failure, Do not confuse no-clean assembly materials (nocleaning required) vs. clean chemistries that must be cleaned. You do not want ionic contaminants on your products.

Dear, has anyone problem after the depanalization of CEM-1 like this (picture in link)? https://drive.google.com/file/d/0B40MYZvzPFWFNnd6ejZYT3k4aVE/view?usp=sharing https://drive.google.com/file/d/0B40MYZvzPFWFaklHQTAydXJ0WFk/view?usp=sharing Is

Folks, discovered an issue this morning where solder joints on PCBs that came out of wash system have turned BLUE! Bare pads and test points also contaminated but not as obvious visually. Looks like it could be a chemical reaction between wash

We test Parts and Components to IPC J-std-002/003. We also use a wetting Balance tester to determine solderability. We also test with SERA. We use ROSA to electrochemically revert the components back to their original state. Need more info ... email
