The general control on QFP fine-pitch coplanarity is +3mils. suggest to look at the re-use of thrown out component from SMT machine. If the component pack in std pack, then most probably the lifted is due to processing, not incoming as the packaging

Hi russ, thanks for answers, I thought that playing with apertures was the solution if paste is able to lose from the screen with fine pitches. But I'll take in consideration all of your remarks for the next designs to be develloped.

Has anyone seen a footprint for these new parts? If so where? Thanks http://america.renesas.com/media/products/common_info/package/mitsubishi/j48fhh.pdf

Without meaning to overstate the obvious or be insulting, IPC publishes SM-782. Their web is: http://www.ipc.org

For fine pitch components we would suggest slow movement of metal squeegee. The effect of angle is minimal. You may check squeegees from Transition Automation they can help you with the holder and the best squeegee. I do not have the web site, Arman

Yes, probing via is perfectly acceptable. Via: * Pad diameter is 0.028 inch * Via pitch minimum is 0.50 inch ... all of which is fairly common, even when probing test pads. [Your English is fine, at least as good a half the English speakers here.]

Randy, We have a Dek 265GSX and 265 MK1. We print 20thou pitch components, 0.5mm. Just make sure you have good board support and USC. aj

Does anyone know the smallest pitch I can print succesfully with type 3 powder for a BGA ?

Yes we have come across 24x20, & we have a couple of feeders set up for it, & no it's not that common a part but you can't be the only Mirae user who has ever tried. What do Mirae have to say?
