Hi there, A little additional point to consider: when doing a "straight" step-and-repeat, it is very easy to generate the instructions to cut a stencil for your SMT board. Take the stencil aperture data and repeat it in X and in Y the given number of times with the given step distances. That's the easy one. However when an image is also rotated, the data needed for a single step is not the normal step distance, but the distance in X and Y from a point on the first image to that same point on the rotated image. Most fab-drawings show these distances between mounting holes, however, most stencil data files don't include mounting hole locations so all dimensional reference between drawings and data file is absent. Ouch - result: delays - frustrations, etc. So when you design one of these types of panels, note what information is available on eve layer. It would be nice if board or panel fiducials were repeated on all layers and were used as reference points. Thanks a lot everyone. Ahne.

I know when you're trying to reduce PCB costs when panelizing, you need to work with your fab vendor when laying out a panel so your panel works with their standard panel sizes. But I've got a few general questions about board orientation within a panel, and board surface finish. ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC's web site (http://www.ipc.org) "On-Line Services" section for additional information.
