Folks, we've recently upgraded to Heller MKIII reflow ovens with Gen 9 cooling units. We're running N2 atmosphere at 1000ppm O2 and Kester256 solder paste. We're seeing a big problem with flux residues building up in the cooling section of the

Hi, I was wondering whether anyone could explain to me, point me in the right direction or send me a schematic on how to build Current Amplifiers. I am building a automated temperature controlled cooling unit and I need to build a current amplifier

Bill--Good morning. We have several decline conveyors w/ conductive black belt Plus cool down units w/ banks of (8) fans. I believe the belt widths are 18". Would that work? Everything is in Illinois. Thanks, Nick Haviland, Electronic Assembly Machin

From “Nick's Software Blog” [http://nicks-software.com/wordpress/tag/list-of-abbreviations/ ] a very cool list of abbreviations … * SCU, Servo control unit or Sub-controller unit (on Fuji machines). * PMC, Placing module controller (on Q.P. Fuji ma

Hi, The only problem with wave is loading the parts, and SMT is lower cost, and faster. We use wave for connectors through, and it works great, as it's fast when there is lots of connectors. I think he's panelizing, so he should be cool on doing m

Many different units used over the years; AC (just cooling); TCU (heating and cooling) and ECU (temperature and humidity)... Let me know exactly what you've got, I'll see what I can offer for manual. www.dekhead.com

I'm actually in the process of phasing in direct inkjet marking on my bare boards. The MEK based inks dry almost on contact, and the machines I have use a videojet excel HD printhead. I'm looking forward to see how it works for us. I think it may

Amejia, If your application is strictly conformal coating and no heat is applied to the board, the product seal and peel would be the solution see link http://www.interfluxusa.com/misc.html This product solidifies immediately on cooling The only dra

Another nuisance with the new SlimKIC - even for Sn-Pb paste we run a little hotter peak temperatures - you can't run another one in succession because the "internal" temperature is too high as well. Typically, I have to put the unit underneath a fa

We concur - we reduced problems by lowering the booster panel to the horizontal and putting two pedestal fans behind the machine blowing onto it - but I think once the ambient air has heated up the cooling effect is reduced of course - we have a smal
