| 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 d

Im trying to get the XY data to program the SMT machines. since i dont have the file, im trying to convert it from the gerber drawing. the closest one to represent the component placement is the solder pad. ive tried using linkcad to convert it to XY

In old days when Zevatech rebadged JUKI machines their was a dos based program that generated JUKI format files from ASCII Centroid data....(would have to premerge with BOM etc) it also could export from JUKI formats to ASCII. SO like others I think

ASk your bare board manufacture for the centriod data. They can do it quickly and most will do it for free. At least we do for our customers.

Problem is I dont have the centroid file. I only have the gerber file...

PROCAM is intended to extract Centroid from the raw Gerber only. You just need to have 2 layers (paste or mask layer - to identify pads, and silk layer - for reference designators). Centroid is the output of PROCAM.

You're in the wrong file. You're looking at solder pad data. You need to look at centroid data. Look here: http://i.screamingcircuits.com/docs/understanding-the-centroid-file-r2-2.pdf We have no relationship, nor receive benefit from the company r

Depending on what X-Y centroid / CAD data you need, there are different SW I've used to do the job. If you need PCB gerber "artwork" (rounds, rectangles, lines, squares,...geometric figures), you can use GraphicCode GC-Place & such - load the gerber

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
