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

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

It is surprising how a simple question sometimes reveals complex issues. It seems from reading many replies that an employee wearing a walkman while working is making a statement about his attitude toward his work and his employer. This is similar to

Hello ricardof, To implement Cpk studies on SMT production equipment, you will require highly accurate glass plates, glass component slugs, accurately manufactured stencils and a measurement system to perform X, Y and Theta positional deviations from

I am not familiar with your flux but with no-cleans (which I use) the primary cause of icicling is the amount of flux solids left on the board prior to wave and how long the board is in the wave (2.5 to 3.5 seconds should be OK). The amount of flux s

Hello markt, If you're only running at 85%, you've got some things to look into! First, it's good you know that you're operating at 85% with some measurables that help you determine that. Now, the easiest methodical way to improve productivity on SMT

Hi floydl, I completely understand when it comes to data crunching after long hours of performing measurements, it's the last and most important arduous task in obtaining performance data. If a measurement and evaluation process that traditionally to

Hello Dave, First you must make sure your measurement system is calibrated for accuracy, repeatability and reproducibility. We perform a standard GR&R Study on our CmController system on a regular basis to ensure that the system itself is capable to
