The main problem I am having is getting the Rising slope 1-3 degrees. If I slow the conveyor down then I have too long of a reflow and if I speed it up then my ramp rate is too high. I was not sure if I need my first zones at a low temp or higher t

Hi, This discussion is really getting long. Fuji and other high speed mounter is great and better than small flexible mounter when it comes to speed.But, I rather suggest a modular mounter specially for subcon companies. Let say we combined 2 or 3 m

I'm in a manufacturing environment with a very high mix of boards, and some low-mid volume. A "large" production run might consist of 100 boards. Volume: There are numerous boards that have a volume of 1-3 pieces. There are a few boards with an annua

I just ran into a reflow profiling problem with a new assembly that we are processing in SMT. There is a cluster of six or so electrolytic caps that measure approx. .710" wide by .660" tall. They are spaced .100" or so apart. When I run a profile, t

Hi Rob, I had tried printig anisotropic conductive adhesive as a replacement for solder paste. Following were my finding. Adv: - curing temp is around 120-150C as compared to 217C (Pb-free) solder. - good electrical conductivity, since it is usual

Thank you- my point exactly and it starts in SMT- operators pulling the wrong paste from the fridge, touch up using the wrong solder wire, etc. My solution- GET THE LEAD OUT!!!!! I'm a CM- high mix, low to medium volumes. No steady all day every day

72 different part numbers, 53 being 8mm, remainder being 12-44mm and 3 tray. It may be low but anymore than 100 and you give up throughput because of feeder locations. And thinking about it, 70-90 is low for a low volume high mix line. I guess if I w

Cliff, I'm sending you by e-mail (don't think I can attach a graphics file here) the doc proof that the problem lies between Atlanta and Ft Lauderdale. This was an attempt to trace your routing. From Cyprus, it crossed the Atlantic by West Orange. U

Snip John, You said a bunch. My biggest problem running Fuji, Panasonic, or Sanyo high speed stuff is that they are meant to run free. They are meant, in my mind, to run as thoroughbreds. I watch 6" reels placed on feeders, pl
