Hi there: During the past weeks (let's say since beginning of the year) we've been experiencing some issues with shifted components. We verify for position before Reflow oven and the components are Ok, but they observe shifted after reflow. it occurs

I am using AIM Electropure SN63/Pb37 Solder, & AIM NC266-3 Flux; just like what ACE recommends. I have both Ultra High Pure T-Tanks and a Cryogenic Dewar Tank for Nitrogen, and neither seems to have improved the problem. I place a piece of tempered

Not sure what's in your line equipment wise, but you need to know relatively what kind of placements per day you run regardless of the mix. We run around 1.1 million across 5 lines in 3 shift. Calculate what kind of placement per day on a specific

Hi all, Why doesn't the ATT teach all the same part numbers some times? The PCB I'm working with has several resistors 0805. I place the footprint over the part and sometimes it goes to all resistor of the same part number. But then I teach another

Dear Gabe, Once you have the mount data in the program, you can move the camera automatically to the location by tracing each location one by one. If I remember it correctly it is done by having the location highlighted in the program and then by pr

We recently purchased some used Quad 4C machines. One of them does not seem to keep a stable origin reference point. I teach the nozzle and component pickup coordinates, then suddenly everything seems to be off by .030 to .040 inches in the X axis. I

How many operator/technician/engineer do you recommend for following SMT assembly line to achieve good uptime and smoothly running quality inspection, NPI process, tehcnical support and maintenance at the same time: - Single shift, 8 hours/day - Pri

Generally, excess solder balls found randomly around the board/parts points to either a dirty stencil during printing, or a stencil/board that is shifting during printing (smearing the paste a little, and causing a dirty stencil. If the apertures ar

Hi Myriam, I think we may need some more information. Is the Electrolytic (Aluminum) Capacitor placed more than once per board? If so, are all locations twisting? This would typically be caused by a thermal imbalance that could be design induced. (u

The best I have seen was two people set up and verify and then two other people not involved with that setup verify. It worked quite well but even then a wrong part was put on. Day shift set up and Afternoon shift thought that both verifications had
