These three come up constantly:<\/p><ul><li><strong>Unclear layer definition.<\/strong> If a single-sided board is designed on the TOP layer without a note, the fabricator can&#8217;t tell which side is front and which is back. The board comes back hard to assemble and hard to solder.<\/li><\/ul><ul><li><strong>Copper pour too close to the board edge.<\/strong> Large copper pours need at least <strong>0.2 mm<\/strong> clearance from the outline. Rout any closer, and the copper can lift during profiling, pulling the solder mask off with it.<\/li><\/ul><ul><li><strong>Filled blocks used as pads.<\/strong> A filled block passes DRC but doesn&#8217;t generate solder-mask data.
