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

Swapping a servo amp out does not lead to an alignment issue unless the new amp is way out of adjustment. Did you do a "drift" adjustment after changing the amp? Does the axis vibrate badly while moving? More likely is someone crashed a head which

Dear All, I am a totally new to the SMT process. In fact, I just had an overview course regarding the whole process of PCBA manufacturing and I have know a bunch of questions in my head. Most of them are linked to the solder paste printing process

until you know if you stencil does align with the pads on the board all the fids in the world will not help you. registration is key. We do it a lot at our facility in Toronto as we have lots of measuring equipment. In cases like this. We lay the ste

Hi bobpan! MOD CODE 69 is "Waffle Tray Handler Installed Flag" and default setting 0. That's what mode code quick reference table says (the reference table that I've to respect according to the previous owner). And it's different what manual says (M

Do you just wish to use the setup as a visual aid to alignment. In which case this is not a bad idea. the only issue you will find yourself finding, is he field of view you will need to get your alignment. I have done this sort of thing with a hybrid
