gerber data vs bare board

Electronics Forum | Sun Sep 12 09:40:04 EDT 1999 | Wayne S.

hello having a problem with one customers bare boards not matching my stencil apertures. i design stencils based on gerber data and reduce up to 15% on some pads. do some board houses reduce pads after receiving gerber data???why would they do that

In most cases PnP files are all that is needed for SMT program generation. BUT, it depends on origin reference of this data as exported to PnP and could be off in X,Y and rotation of image pending when PnP Data is exported. Also Rotation of parts

I agree, in Essemtec's case all they needed to to make that 100% friendlier was let the layout visualiser be able to read and display some gerber data (paste and overlay). Otherwise the offline solution is to hold up a blank board/printout to verify

In my experience the main advantage of the ASCII CAD format is that it combines the centroid data, rotations, and package information for your CAM software (at least it does for what we use) to draw the part shapes into the visual assembly aids. If

Some Customers normally don't share CAD data in order not to copy the design. What you can do is use the Pick and Place file then plot to the pcb paste/silkscreen layer of the gerber using software. Not sure if your universal machine can load a gerb

Hi Ivan, Our solution works with 3 type of data with XY: 1. CAD - the best choice but, as you mention, I isn't available for all products. From our experience, it is available in 30%-50% of products. 2. IPC - This file available in 80%-90% of produc

hi Bob, Thanks for the info. I understand your comments, but I am looking for specific guidance, If I am putting chip capacitors on a .063 FR4 board, what size package should we stay away from to avoid cracking? (I realize this is dependent on h
