Thanks for the quick reply :) We've used some classic feeders that we repurposed ourselves by switching the original optical barriers (index wheel and motor wheel) with twice the resolution. It gives okayish results, not great, but the 0402 is alig

Welcome. First, proper alignment can produce an order-of-magnitude increase in the number of boards that can be printed without wiping. The initial alignment can be made either by: * Peering through the stencil apertures at the board underneath and

If you have concluded that it is not a file storage problem you may wish to consider - When setting up a job the camera can move to virtually any position. This does not mean that the actuators on the stencil or board have enough travel to align the

Hi everyone, this is my first time on this forum. I've only been an innocent bystander. Until now. I wonder if anyone out there knows of any technical publication (accessible over the net) that explains, in detail, the actual physics involved regardi

here is how it is done. 1.Position the stencil in the machine. 2.Position the board onto the PCB tooling as close to being aligned with the stencil as you can. 3.Place mylar or some thin clear material over the board. your printer should have prov

Major advance: Productionization of SMT. Minor advances: * Realization and control of solder paste characteristics * Vision alignment controls in printers. * Evolution from mechanical centering [through laser alignment controls] to vision alignment

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

Thanks Sarason, Laser alignment of components was actually our first attempt - it certainly offers speed and accuracy, but purchasing cyberoptics units would blow the budget & getting round their patent not really an option. I've seen the Essemtec
