I'm looking at some Pillarhouse and Juki machines used. Does anyone have a strong preference on selective soldering brands? What's the life time on machine? Is buying a 10 year old machine a waste of time? What are you doing for nitrogen? I'm current

I'd have to disagree with the Electrovert applications guy. I'd recommend SLOWING down the conveyor between .5 to 1 FPM - effectively, you're REDUCING contact length (because contact length = dwell time * conveyor speed), hence getting better peel-o

Adam, I would first check hole to lead sizes on the components that you are having hole fill issues with to see that the spacing is withing spec. Second, check for oxides on lead tips, and contaminated leads that cause poor wetting and insufficient

I am not using a solder pallet, I don't think the problem is contamination related, because these parts are on some of our other assemblies, and they're being waved with no problems. The problem seems to be mainly on our panelized boards for some rea

I have been involved with our Selective Soldering process for 15 years or more. Using ACE Protech machines and now a Juki. Our first ACE machine replaced 4 hand solder operators easily, allowing them to work on other projects. The machine isn't "set
