 Topic: DRC errors from Altium gang maskPosted: 16 hours 14 minutes ago at 9:17pm |

Hello, I created a footprint for a 0.4mm pitch SON device (SON11P40_200X250X80L35X20T140X120N) for Altium Designer. Because the pitch between pads was so small, PCBExpert generated a gang mask over the pads. Apparently the software uses multiple overlapping objects to create the gang mask. It looks like the masks are overlapping properly, but for some reason Altium generates DRC failures. I have a solder mask sliver rule limit of 3 mils in the Altium design rules. Am I doing something wrong? Do you have a suggested workaround? Tom Yunghans 3526 Glen Ave Carlsbad, CA 92010 (714) 336-9503 uploads/16542/solder_mask_sliver_errors_from_gang_mask.jpg

In previous versions of Footprint Expert, the Gang Mask was drawn with multiple overlapping objects. In the V26.10 release, Gand Mask is drawn with a single drafting outline. Also, V27.01 pre-release is available to download and test. |
