Hi,
Is there a special reason why odb++ output deletes non plated holes which contains no regular pad, thermal pad and anti pad? The padstack only contains the drill size + symbol and all the pad info is None.
I discovered this error after I got feedback from the manufacturer. Apparently the drill showed up in the gerber and NC drill output, but not on the odb++ output data. They used odb++ data and not the gerber data. The strange thing is that the drill table, in the odb++ data, showed the non plated drills with the character 'k' I defined, but weren't present on the location I placed them.
After adding a thermal and anti pad to the padstack, odb++ didn't delete the drills. I'm only using positive planes, so why should I even use thermal and anti pad?
They software version I use: OrCAD PCB Designer Professional 17.2-2016 S051
Regards,
Michiel
