Yes, most of my fiducials are 1 mm. BUT, you may consider going 1.5mm or even better 2 mm because in my experience PCB manufacturers will NOT check fiducial shape during PCB testing. This goes for fiducials that are placed on panel frame. Fiducilas t

ZAM_BRI- I don't know how effective this may be but some points to include in the buy-off procedure: Before submitting the PO for the stencil you may also want to do a CAD to Stencil comparison to verify correct apertures.There are SW packages and co

Hi there, It looks weird how you handled the problem. Just a thought, but would you check the stencil and may be recut a new one, making sure you have the image exactly in the center and have the fiducials exactly where you want them and the frame

Michael, Good afternoon. My experience with the frameless stencils has been less than optimal. I tried the universal stencil system about a year ago and these are my experiences. 1) The stencil manufacturer supplied me with a free frame to try ou

We are looking into using Scored PWB's on a new high volume design. We've used Tab Routed PWB's exclusively in the past. I understand that Scored PWB's are more efficient to produce and depanelize. Question: What are the industry standards for cr

The answer you are looking for is part of your initial setup of the board and stencil. This information is to be found in the PCB setup menu/icon. The reason why the stencil loading pins are impacting the frame is because the default setting of the s

| Has anyone used the mechanical stencil foil tensioning system from certain company that eliminates using stencil frames and epoxy & mesh? Any comments on whether it's worth looking into? We go through product revisions like we go through clean so

I appreciate the detailed reply. However, I had tried dimensioning the stencil to everything imaginable, including the correct/measured dimensions. Interestingly enough, after loading a new stencil into our adaptor, I had no errors with the new pro

MPM uses a one-print-Mylar system, as do other printer mfrs. In this system there is a Mylar sheet attached to a frame that is secured over the printer table with the board on it. You print onto the Mylar. The table X-Y-theta manual adjustments are u

| 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
