Sand is not a great conductor, compared to copper. Never heard of using the stuff on RF boards. Our board fabricator uses Dupont CP100, now CP101, [or something like that cuse who's going to check?] when plugging via on cheap boards. Your board fa

This is a good idea. Heck, you could fill the bags with sand, if you wanted. Like anything else in the shop, bean bags require attention and maintenance. If you don't, eventually the seams on the bags loosen / break and you have to do a "clean-u

Bert- There's alot of forums dealing with SMT and Fuji in particular but you'd have to be able to read Chinese. In China... being fairly new to this there are many help forums around designed to assist folks to get up to speed as quickly as possible

Do a dirty DoE...print ten boards with the worst error you think you can accept, build them up, and count print related defects. At the same time, print ten spot-on and proceed the same. If you don't have any more defects on the off-print batch show

Stephen- I'm curious about your statement regarding someone mistakenly thinking it would be a good idea to get more done in China. I fail to see the mistake in such an approach. Consider if DEK or MPM felt that way a few years ago. They would both

How is the component marked. Is it ink marked, laser marked or what? What is the material that the marking on? What volume are you looking at? We used a small, pencil-sized sand blaster, loaded with bicarbonate of soda to errode the mark off of plast

Q1: Can they be masked so parylene doesn't get underneath? A1: Your parylene applyer may be able to mask area, but in general no. This stuff is cured in a vacuum chamber to make sure that it gets into every past corner. Q2: How do you remove and re

Are you using 08MPF nozzles with front lighting? If so, these nozzles wear quickly if you place a lot of chip caps and resistors. I was using the 3500 vision system and found the vision recognized the nozzle once it was worn and became shiny. You
