I am using AIM Electropure SN63/Pb37 Solder, & AIM NC266-3 Flux; just like what ACE recommends. I have both Ultra High Pure T-Tanks and a Cryogenic Dewar Tank for Nitrogen, and neither seems to have improved the problem. I place a piece of tempered

We are having difficulty with bridging on a 2x50 pin 0.050" fine pitch connector using our selective soldering machine. It usually bridges at the end of the row, but sometimes it bridges all the pins together as it drags across (solid bridging). I

We recently installed a new solder wave machine, The spray fluxer has a pressurized tank and because we use an alcohol based flux, the spray fluxer system must be fed with nitrogen. Anyone has infos on what installation is prefered to supply this mac

I would discourage the use of city water at all - where rinsing electronic parts is concerned, it contains too much contamination. If practical, route DI water to your first tank and implement some aggitation (either nitrogen bubbles from the bottom

The onsite generator drops approx. 30psi from the input. We feed ours 110psi and end up around 80psi in the tank, which we regulate to 65psi for the machines.

First thing try a different solder paste. All solder pastes are not created equal. Also if everything else on the board looks good then check the part. As far as nitrogen goes its about 4 bucket loads you need an external tank. I have seen some marg

Our nitrogen generator and an air drying unit came with the selective solder machine when it was purchased new in 2008 as a package deal. We originally were feeding the system with air that was not properly dried. That lead to some maintenance cost

I did some investigating and it seemed that getting a reflow oven with an inert atmosphere could be the answer to the inconsistant wetting issues that we are having with a leadfree DFN-10 on one of our products. Here's my question(s). It seems that

What are the continuing costs on the N2 generator? Is there replaceable media that needs to be monitored/replaced at regular intervals to maintain N2 generation? We're currently using tank-supplied N2, but are just getting ready to fire up our sele

We are a high mix/low volume shop (avg. lot size is about 60). Hand solder was a bottleneck, so we looked into selective machines. We purchased a Vitronics-Soltec mySelective and are very happy with it so far. Although it has a large footprint, ev
