Posting here because all the threads asking for feedback on it are locked. We have been extremely happy with the 4300 tacky flux for BGA attachment. Not only is it both washable and no-clean (i.e. wash-optional), it was also the only tacky flux tha

We have been using the Amtech line for over 12 years now with all of our PCB and BGA Rework. The NWS-4400 is mildly active and will give better results with Lead Free Solder. Note that the LF-4300 is considered a No-Clean. However it will show lea

Has anyone experimented with the Amtech 4300 flux that claims to be a no-clean flux that is easily removed with water? If so, how did it go? Is this flux truly removable with water only while creating adequate solder joints? -OtheRuss

I, too, have finished qualifying the Amtech paste for a dispensing application. We will be experimenting with the component soldering/stencil printing next. The stuff has proven to provide the best of both the no-clean/low solids and water washable

Good question, we are a distributor and have offered lots of different magnifiers. We finally decided to stick with only one brand. It's not the least expensive but the quality and warranty are superior to any other. That would be OC White. I replac

I have a customer that is having a flux residue problem after wave soldering. Flux is roaring through the board to the top side and leaving a residue. This is only happening on the flat stamped leads. The round leads are fine. They are using Supe

No problem running lead free without nitrogen. Careful profiling will take care of the soldering. Cosmetically, the Nitrogen reflow is superior for lead free, and we see much better wetting, better coverage of the PWB pads, and of course the smooth

I have found Superior No. 75 to be an absolute miracle worker when it comes to nozzle maintenance. I let our worst nozzles soak in that over the weekend and then the majority of the dross would literally flake off with light pressure from a pick/scre

We did a tin bath on ours but it was provided for free by Nihon Superior so that is a no-brainer. It was better than taking a risk of having to dump the pot. If you cant get a free tin bath, then you should probably go ahead and fill it half way or s

Hi Cory, As a manufacturer of aqueous cleaning systems, my advise is somewhat biased, however I believe it to be accurate. We have hundreds of customers who have implemented no-clean programs. The programs have been successful when measuring the r
