So, what is a �Contaval Pallet�? And who, my I ask, came-up with the cockamamie idea of retrofiting of the edge hold conveyor? Last time I checked, everything was fine, all profiles were working, etc., etc. Just think, if you move the fixed rail i

The primary driver to the set points for your oven is not the board or the number of zones in your oven. It's your paste. If you need a "ball park" guesstimate as a starting point, your equipment supplier is probably the best place to start. So fo

A customer specs .1% thin film 0805s on one product. The parts that came in the kit were marked 1002, and I suspect they were just 1%ers that were sorted for the tighter tolerance. We were a few short, ordered the balance and got parts marked 103 w

Howdy Bolo, I see. I currently run a 5 zone 1500 Heller, It's a very nice reflow oven and one of my favorites. Hopefully in July we will be getting in our 1700 from Heller. These reflow ovens (used) can be had for a pretty decent price at least in

The nameplate specs for a 2004 Heller 1088EXL show 240V 60A, and specify Largest Heater Load of 25A. As each of the 8 heater elements is 6000W or 9.5R, how does this really work? Obviously all 8 elements on would pull 200A, so does the machine only

Hi ProcEng1, I have no clue what removable hard drive adapter you mean. I have 2.5" SSD hard drive connected directly to PC board by regular Sata cable.
