When we found this to be a problem with some QFP 100's (.020" pitch, and our first experience with fine pitch - 48 of them on a 2-up panel), we saw that the solder was running up the leads during reflow and staying there, leaving the fillets thin or

And this relates to robots soldering? You need > to remove yourself sirl. Hello, we do have some experience with a solder-iron robot. Tried several types and brands. Now we have 2 very good robots, works perfect, the type of robot and solderwire

Hi. We appear to have a basic grip on using the CAD2CAD tool v1.5 from Assembleon for our PCB designs. Can anyone offer advice on how to take our PCB design and allow us to panelize the single PCB to say 2-up or 4-up, etc. So that we can visualize th

I am quoting a new job and am wondering if I should use carrier pallets for it. There are 2 PCBAs both are 31mil thick. One is about 16 inches long, and the other about 13 inches long. Both are 1.4 inches wide. I was thinking to put them in a 2 u

We have a pretty challenging board (2-up panel, 15"x20", 48 20mil pitch QFP 100's and 2 25mil QFP128) that gives us LOTS of lead bridging on the 20 mil parts. There is typically very poor wetting on these parts also, and some joints just flat aren't

I've got a new board (actually a new panel...a 4 up, with one row rotated, where it was a 2 up panel with no rotation before) that runs fine on the IVc but not on the IIIc. I've used the same reference points for the image rotation (fiducials) on bot

There are many rules, but balance is the key. It all depends on your processes, type of equipment you plan to run the panel through, as well as the type of components going onto the board. If your single up circuit has 6 thru-hole caps, 5 connector

Do the math first. 10,000 boards a month means 440 boards a day (roughly, and not including weekends). Do you plan 2 shifts or only one? If one, you need to produce a board about every minute if you work an 8 hour shift. If all 110 parts are on on
