I tend to get issue on and off with the feeders either stalling and/or running slow/noisy. They are actually pretty easy to clean and maintain. If you take off the side panel of the feeder you will see a few gears, belts and a motor. The first thin

Patrick- You have not given enought detail of the type of discoloration. Is it "white residue"? Can it be "rust" colored? Whatever it is, you fab supplier needs to be called in immediately and give you an exact reason for this failure. Just rubbing

Sounds like the mask to me. Had a similar situation a couple years ago. The mask wasn't fully cured, so it absorbed water that the preheaters couldn't dry out. When it outgassed at the wave, it caused a lot of micro turbulence that broke the surfa

Hi all: We are seeing "solder webbing" on the bottom side of some of our PCBs after wave solder. The solder is sticking (like a spider web) to the solder mask on the PCB. This is only happening on 2 of the many PCBs we wave on that machine. Both o

Frank, I am not talking about the masking on the PCB. I am actually talking about the masking on the solder side of the BGA. We have a very very high dollar BGA and are trying to reclaim alot for reuse. When we remove the BGA from the assembly, you

Having read about your "dream", I can sympathize but gotta ask why did you feel compelled to write about this on a Sunday at noon? could it be that Chorizo enchilada with pickle sauce, downed with a jug of Ouzo on Saturday night have something to do

Yet Again Dave spills his pearls of wisdom. Dave is correct in the moisture content wood absorbs. I know we have all visited factories with wood board holders and such. I have actually seen wood carts with drag chains. Also, keep in mind static can b

Hi All; The following is from our Support people who worked with Fuji on the problem; Last week Luke Mittur and John Gudel were in from Fuji to address the IP3 issue outlined below. The problem ended up being that the table "up" and table "dow

Big BIG BIGG wave with a lot of preheat capability both top and bottom. You may need to exceed the standard "100 C" top side preheat to 120C or so (be aware of any topside SMT going into reflow over the wave). A spray fluxer with very fine atomizati

This is embarassing. I've used ipa (actually "70/30 rubbing" alcohol) to clean these for a better view (this is a no-clean), and found the above described anomaly to be intact. So, I assumed it was something in the solder itself. Well, today I us
