From my past experience, you can usually get away with OUT the chip wave if your SMD's are no smaller that 0805, and more importantly, there are no SOT23's. A nice, clean, inerted laminar wave (with a little smart or omega help) will solder your S

A keypad overlay is used to adapt one basic keypad design to a variety of applications. The overlay is positioned on top of the key board to match functions on the overlay with buttons on the keypad. The user selects a function on the by pressing t

Brian, We had similar problem in our inline wash machine time ago. We checked everythin on equipment (filters, DI water purity, sprayers angle, etc). To make the long story short, we found out that the problem was caused by a new solder paste. This s

Sami, Have you tried anything to reduce your print time. For example, use the fewest fiducials possible (2 in most cases) for alignment. Get rid of unnecessary inspection sites. Adjust the start/stop of your stroke to reduce wasted movement of th

Edited because I completely misinterpreted your post. We used 2 lengths of Durapol with slots for the board edges and a shorty (free-floating, not attached) under the middle. Not much more elaborate than your titanium shims but we had it laying aro

We run a TP9 machine and had a very similar problem with it. On a TP9 machine there is a power supply board where all the voltages are generated. It is located on the bottom side of the unit. The problen was with one of the fuse holders. The co

&F(27).NO4=0 NO4 is for the prep head, which you probably don't have. So, it is zero to mean don't use the prep head. &F(27).DSPF=1 This is the "display flag", it apparently means this component slot in the file contains valid data for a real compon

I don't know much about Hellers other than the 1500 models which don't have blower speed adjustments (except for cooling), but with that much air flow I'd be worried about over working your heater elements. Have you checked in zone setups to see ho

Patrick, Back in my rich OEM days, i actually DID measure mg/in^2. I bought a scale, which measured in mg, specifically for this. Basically, took a blank PCB, took a "before" weight, sprayed it, and then took an "after" weight. I measured at diffe

Hi, Yes, we just built a new plant, and used copper again. The stuff we cut out of the old building was copper, and it was fine without any issues. We lay it on an angle so condensation flows to an end, and can be periodically vented, and we take a
