Yeh, the IPC courtyards are for old ladies. I want to say that at one time IPC was talking about a new set of rules. Maybe, 7351 - SMT Footprint Design Guidelines??? Anyhow, Jim Blankenhorn at SMTPlus [ sales@smtplus.com ] has done THE best job o

Hi, I have been checking into the Universal machine, and it also looks good. I am now trying to work out what the advantages and disadvantages are between the Universal or Fuji machines are. It's hard to decide. Does anyone have experiences with bo

From my understanding paste on BGA pads are applied only to help in holding the component as the PCB is conveyed during the manufacturing process then soldered. But during rework on BGA's do I have to apply Solder Paste or just Flux? What's the diffe

You better get to know who the third party service companies are because Fuji just does not care about service they rely on their reputation. If you wanted good service you should have gone with Universal. When you compare machines now days all of th

This is a real old machine. You won't have much luck with Weller. They sell a unit that they think is much more current. Nozzles are to come by, but are necessary for different size parts. Look on E-bay if you haven't. You also might find a deal on a

My company is looking at the various options for selective soldering machines. We are mostly a low volume, high mix facility, with some moderate volume orders as well. I have looked at the Pillarhouse Topaz XL, Ersa Versaflow, and Vitronics Soltec

We have now switched to Kester EP256. During our solder paste evaluation, resistance to humidity was one of the selection criteria. We printed multiple boards, then exposed them to 85�F/65% RH. At 30 minutes, 1 hour, 2 hours, and 4 hours exposure

Could anyone tell me the difference in PCB material Nelco13 and FR4? PCB dielectric material Nelco13 is quite new for me and I knew nothing about it. For imcoming quality control (IQC), I am asked to identify PCB made of FR4 and Nelco13. How to do th

Probably every shop on the planet uses QC-types differently. They inspect boards for us, based on a sampling plan and work instructions for that board. When they find a problem, they put a little adhesive arrow on the board that points to the probl
