We had a Quad 4C that was fitted with a dispensing nozzle. It was perfect for jobs like this. Place the 1st component in the paste, add a dot or 2 of paste to the top of that part and then place the 2nd component on top. I beleive that you may be ta

We installed a Soltec Delta 3 a few months ago and have been trying to run with a VOC free no clean. We're using SN100C in the pot. We are spraying the material and have top/bottom preheat. Evaporation of the water in the flux is a bit of a stru

gregp: Our PTH process has not changed in many years. Our products are fairly simple as far as electronics goes and everything gets potted anyways. ~90% of everything we build is single sided TH with ~ 100 solder joints per board. Each board is ~

I have used a 2006 Electrovert Vectra ES (63/37) for last 3 years, we acquired it used. It had little or no maintenance before we got it, now after replacing a solder pump motor, preheater fans and thermocouples it is pretty reliable. The spray fluxe

Hi, We have spent the day trying to profile our Vitroncis Soltec Delta C wave with the new SN100C solder, but having problems with the heavy pins on some BNC connectors we are using. We have Interflux no residue flux, and we are using palettes, whi

This is one of the biggest mistakes with the Lead Free process. We have all listened to the 'industry experts' and followed their advice and unfortunately got it wrong. Keep the dwell times (dependant on alloy selection) the same as Leaded so you are
