This looks like it may be a good application for an Air-Vac or Wenesco type solder station. It is a solder pot that has a small motor to pump solder up through a chimney. You can put different nozzles on the top of the chimney, so you only apply sold

The most effective method is to monitor both printing results and parameters. Periodically (maybe once per month), run QCCalc or another program to measure the machine's capability to hold its set parameters. I also run control charts on the paste h

I'm not talking about buying components. I want to know how would you go about setting up an SMT line from scratch. Or, maybe more specifically, how do I convince management, with data to back up all my arguments, that this is not a good idea. That

There seems to be less play in the pocket than with other parts i've loaded. I was assuming the large nozzle would work better but for reasons unknown to me it didn't. I also tried a 1mm and had parts all over the machine (can you say hand place 100+

We need to remember here that as printer manufacturers were enhancing their product lines, miniaturization was quickly being developed in the background. In the last 2 years I was involved in developing and conducting a D.O.E./F.M.E.A in determining

Hi Dilbert I do not know if you meant to use the words argue in your posting, but assuming it was not sarcastic I would like to offer my point of view as an equipment supplier to people like you. First the customer is not always right but they are

I'm not saying that an eraser will necessarily work. What I'm saying is that some erasers may cause more trouble than the eliminate. Look here http://aic.stanford.edu/jaic/articles/jaic28-02-003_2.html We prefer a brand called Ruby Red. The "ole

Genny, you may want to look at the brds you will be running and identify the various packages. I do not know what a standard package is. Most chip resistor and capacitors, 0402, 0603, 1206, 1210's are on 8mm feeders, but ic's vary quite a bit. Also r

Dave, I've had a few intersting conversations with Dr Lee, now there's a guy who know's stuff, but as it turn's out even he doesn't have all the answers on why things void. Many of his papers point towards oxides or contamination on the ball, so age

Hi everybody, This is a simple posting to initiate a discussion on different ways to troubleshoot, improve, and control the Stencil Printing Process SPP in SMT manufacturing. There are many SPC, ANOVA and other analysis techniques that provide insi
