We recently added an SPM printer to our SMT department and I need to buy some tooling pins and center supports. Other than MPM, is there any aftermarket support for this machine? Can anyone point me towards any suppliers for the above mentioned parts

QFN soldering

We have found differing results based on the pattern used when reducing to total % of solder paste on the center pad. We arrived at 68% coverage on the center pad, and 1:1 for the perimeter pads. To get the 68% coverage we used a number of differen

Louie, We'd be interested in your experience with the stainless centering jaws. We just ran a job with heavy 0402 placements, and had a rough time with it. After much work on the package, magazine centering, etc, I've concluded the issue is the ce

Vitronics oven corner grounded delta?

I have a new (to me) Vitronics XPM3 oven which we're hooking up. It requires 480V, and I only have real 208V in the facility. I have a transformered up 480 subsystem, but its corner grounded rather than center grounded. The XPM3 manual suggests tha

Mydata TP9-2 and TP11-UFP difference

Electronics Forum | Thu Jul 18 17:41:31 EDT 2019 | rgduval

The UFP was a designation for "ultra-fine-pitch"; but, for the most part, you should be able to get the same placements out of both machines. Anything 0402 or above can be mechanically centered. The UFP machine will lean on optical centering for .5

We just went through a similar issue with our MY12E. Make sure your Midas vacuum system is working, check your Midas Z friction. Also verify the Centering unit centering band. You can swap your MOTZ and MOTC to rule out the card. The tool install t
