I don't know how your printer could match the board's alignment to the stencil if they aren't. If you don't have fids on both board and stencil that match you'd have to use pads, but then you've got apertures thrown in to the mix. If that's the sit

Does Ekra or MPM require stencil fiducials be filled with Black Max or some other black epoxy? We still require our stencil supplier to do this. I did not have to do this on any Dek solder printers since 1997. Can the MPM UP2000 HiE fiducial light

we use A EKRA X5 it can use A pad our the fiducial I generaly use A pab becuse most of our stencil don't come with the fiducials on them and our boards our HASAL and the fids our domed most of the time the smt pads work better for me

We use an EKRA E4 printer, but the concept sounds the same as far as the fiducial alignment goes. I have found that SOT-23 components work the best for fiducials - and I always make it a point to use them on our older PCB's (where the screens do not

I started a new job about 6 months ago, and the screen printer is an Ekra E4. I have never used one before, but have used a variety of them and I have 13 years experience mainly in surface mount. I cannot seem to get consistency out of this machine

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)
