Once the panel layout is finished, we send that Gerber file to both the stencil manufacturer and the fixture manufacturer and they use the step/repeat info from that Gerber file to create the stencil and the reflow fixtures/wave pallets, etc. The assembly print contains only the one-up assembly information and print notes. The fab board print contains both the one-up dimensional drawing information, and also the panel dimensional information on a separate sheet, but it is all within the fab drawing (not a separate panel drawing). The panel drawing includes the drill data for the panel and the location for the panel fiducials, the one-up fab data/print includes the drill data within the individual board and the individual board fiducial location(s). -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Phillip Bavaro Sent: Monday, February 19, 2007 2:43 PM To: [log in to unmask] Subject: Re: [TN] PWB panels Hi Jim, When we (sometimes) create a board mechanical constraints drawing, and use a schematic to design the gerber layout (one up), then we create a dwg for the panel based on optimized input from the team and board fab shops, which finally results in Gerber which includes the panel but only has one location populated. The pwb house then uses the Gerber and the panelized drawing to "format" the panel (for example: AB flip, 180 degree rotations, etc.) Having said that, I am interested to see how others deal with creating the stencil for a multi-up panel. Where in your process is the stencil gerber data created for a multi-up panel? Is it created by the designers, or is it step and repeated (flipped, rotated, etc) by the stencil house? Or does Manufacturing do it? What about if you use multiple outside design houses? Thanks in advance, Phil At 02:07 PM 2/19/2007 -0500, Marsico, James wrote: >Hello TechNet... > >A quick question.
