    Hello gurus, I am a hardware designer with a small company. We are about to send a new PCB for fabrication. This board uses dozens of tiny QFN, DFN, and similar packages. As a final check I have been going through the datasheets of all these parts to verify the land patterns and found out that many IC manufacturers recommend using NSMD pads. Unfortunately, this is not what we have now in the design. Our solder mask opening is equal to the copper pad size. Some of these copper pads are only 0.
