Worked on these for many years as a Speedline FSE, now doing my own thing. You could have motion or alignment issues in the printhead. The setting in the INI could be wrong, but unlikely. Or are you just using the wrong squeegees. Without a stenc

Solderpaste types have a big effect on print performance. Go to this link to see if the solderpaste you are using has been tested, see "Rheometric Pump Paste Tests" under MPM: http://www.speedlinetech.com/news_publications/application-notes.aspx?OnI

I do not use MPM printers but I find it hard to believe there would be a problem, assuming the MPM printer can be configured for Edge reference stencils. The double image stencil is basically two edge reference stencils in one. Assuming the art work

Dedicated tooling uses what MPM calls an "H" tower. You mount the board support plate (dedicated tooling) on top of the H tower. If boards are only single-sided SMT, meaning only components on one side, the board support plate is flat with vacuum hol

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

Thanks for the reply, this is something that I am actually still fighting. I've been working with MPM directly since we ended up getting a service agreement, but I'm honestly not much closer to figuring it out today then I was when I first posted th

Why would you have a stencil made without knowing the capabilities of your equipment?!!? Ok, the manager in me has spoken, you can cut a few hundred bucks off a stencil by putting two on one, but the reply Michael has posted brings up many other iss

I have recently completed a HUGE screen-printing DOE. I used Taguchi methodology and man I got good results! Here is what I learned for what it's worth: (p.s. to the MPM apps guy I sent a copy to Tim Gillis, Lou Fuda, etc...) EFab vs. Laser: EFab
