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

I've been using metal blades on several brands of printers over the past few years and have to agree with comments in other replies. Contact print is a must or you will tear slits in your stencils at the ends of the blade. Center-mounted (floating) s

Thanks for your response. This is a DeHaart MPC-29. It has manual vision, no conveyor. When I bought it, only one camera was working. I fixed that, but while I was jacking with that, the electronic pressure regulator (spcjr) burned up without warning

Pressure printing systems Conventional stencil printing techniques have fundamental limitations as regards paste handling: The volume of paste available for printing is limited, so frequent replenishment is necessary Paste is difficult to c

Hi Clarissa, seems to be a real start up situation you are in. For the printing there is IMO no need to buy any sophisticated automatic-vision-alignment-self-cleaning-inline-and-more-machine. Features you need: - adjustable in X-,Y-,Z-axis (individu

Hi Folks, just wondering if anyone else agrees that Rheometric pumps do not work and are more trouble than they're worth. They do not circulate the solder paste properly. The only solder paste that is processed on a FIFO basis is the materia

I beta tested these 6 months before general availability. These devices worked well in some situations and mrginally in others. Migrating to Gel may depend on what your current issues are with your current tooling solutions. Generally speaking it w

My suggestion is to conduct a Design For Manufacturing (DFM)study on the assembly in question. Pay particular attention to the pad sizes, component lead dimensions and satisfy yourself that those two factors are correct. Given that pads match compone
