Good day, Problem appears only with 0.5mm pitch components. Print quality for these components is unacceptable. Paste type isn�t new for us. No any tape on the bottom of the stencil. We apply enough pressure on squeegees, stencil remains clear after

dman97, There is a calibration procedure. It is fairly straight forward and will take about 30 minutes. When you reset you machine both of the squeegee mounting blocks/fixtures should be level with each other. Just slide you finger over the fron

I can't say that I have an answer as to fixing the mechanics of your issue. However, doesn't that machine have an auto blade height? If so, even with one blade lower than the other, the blade height should only depend on stencil height. I could be co

| Hello | | Having a problem with bridging on 20mil pitch qfp, only on the lead groups where squeegee goes over width of apertures. Using MPM sp-200 semi-auto, chem-etch stencil, 9-10mil width opening | 100 durometer blade. Getting "tails" on deposi

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

Thinking about this auto-mode on Grid-Lok..... Ok, the board is warped, lets say positively, the pins conform to the warped board... what about the effect on top side and squeegee pressure? It will be much higher and could damage stencils, right? Pos

I used an Ultraprint 2000 so if that's what you use then maybe I might be able to help. First, I'm assuming that you've already passed the Teach New Board section. This is board dimension, X and Y boardstop, stencil/squeegee heights and strokes. If

We have an MPM UP2000 stencil printer and have a lot of issues with burned out 6410 driver cards (or driver cards just failing to work). I have looked over these threads and found that this is a common issue with these cards. I understand that thes

Simple differences. Both processes require a very similar machine platform, controlled motion, vision fiducial recognition and alignment of a substrate (PCB or hybrid ceramic) to the "image", the image being either a stencil (hence stencil printing)

| SMT-ers | | I notice that most suppliers provide data that is eye-catching but avoid providing data of significant technical relevance, such as Cp and Cpk. It would perhaps be a wise idea for standards to be formulated in this area. | For
