I'd like to hear from anyone regarding the use of Data-PAQ's new Rapid Oven Set-Up software. This looks ideal for our low volume, high mix environment. Anyone having any comments good or bad would certainly be appreciated. Thanks, Ron

We are starting to see a large increase in the use of through board gold plated connectors that require hand soldering with the limitation of .o6" encroachment up the pin. What is the best way to accomplish this? we currently scrap about 5-10% of t

We want to perform a "design of experiments" session to determine the optimum settings for our pasteprinter.We will design a stencil with decreasing aperture-sizes to make it measurable where the printing stops. The result should be a measureable pri

On an assembly reflowed in air saw the same thing: 0201's with a grainular solder joint, but 0402's and above with perfectly formed joints. Reflow profile all within acceptable tolerances. Reflowing in nitrogen solves this problem, but increases t

350 candlepower is fairly low for high detail work. I spent some time in the construction industry laying out electrical blueprints for schools, and such. It was desirable to have more in the order of 700 fc for the desk surface that kids would wor

Thanks Dave. My engineers are not going to like the news but it's good for me. Maybe now they will use 0603s instead of the 0402s which are not required due to plenty of board space being available. They want to do 0402s just because we now have a

Check your land patterns. I believe someone once made a typo on specs for land pattern spacing and the specs are still being used by some people. I worked for a CM that had a customer that spaced the pads for 0402's too far apart. It was the only

I would look at Universal for sure. They have a ton of late model Chip placer's and GSM's that they will discount heavy. There are so many used GSM's and HSP's on the market you could probably get what you need for a fraction of the cost. You could p

If you can solder in an inert atmosphere you'll find the problem will disappear, even blowing N2 over the surface while soldering will solve the problem. 10�C over peak is not excessive, I've run up to 350�C in some cases, protected by N2 the flux wi

When you ask for data in terms of rework, do you want reflow solder yields versus wave solder yields? Or do you want repair data from each process, or yield data that shows actual glue defects from screen printing versus solder paste screen printing
