haha....thanks Steve!!! Nozzle Height of 1 means that you have dust or something in the quadalign lens. You need to clean the lens with alcohol then a dry lint free cloth and if it stays the same....that means the lens has an issue or there is dirt

Herb: Try oversizing your stencil fiducial openings to maybe twice the size of the board fiducial. When aligning manually, look for uniformity in the annular ring which appears around the fiducial. Hope this helps.....

I have no opinion on the accuracy and repeatability tolerances you should be looking for on the vision system and the actual alignment of the stencil. I expect Cp=2 from my printer.

hi, we used to place SMDs with adhesive and wave solder machines. Now we try to work with an old stencil printer that we have ane then reflow, and we have no experience.Can anyone tell us by which method stencils are aligned using the 2 cameras of th

what is the manufacturer and model of the printer you are planning to use? actually, if its a semi-automatic machine you may not need the cameras to align the stencil to the board. you can "bomb-site" it.

MiniMicro stencil has stencils and a holder/aligner. I use their stencils but have not used their tooling. I use the eyeball align - tape and secure method. www.minimicrostencil.com Not affiliated with in any way. Russ

we are experiencing a lot of components mis-aligned , Can anyone suggest me some causes of this defect. regards

This is brutal. O.Tarango, I think the techs on this forum need a bit more detail from you. There are only a million or so possibilities why your components are being mis-aligned.

Firstable, thanks for all your comments,sorry if my question was too un detailed, I really need your help on this, actually we are using a 4796 HSP in our SMT process most of the incidences of mis aligned component are on two 0420's capacitors Rega

Please give mesome guidelines for our pick and place machine (Juki)because we always encounter mis-alignment and missing components.
