OCTOBER 2021 I DESIGN007 MAGAZINE 53 Even one misstep in this category can create problems down the road. ough the list may seem long, the potential return on investment of a few minutes can be significant. Check Solder Mask Layers When you are double-checking each board layer, pay careful attention to solder mask lay- ers. Oversights here not only can cause delays but result in boards that do not function prop- erly or at all. • Do all pins have mask openings? • Vias under components should not have mask openings. Do they? • Are solder mask openings slightly larger— at least 0.004"—than component pads? • Are plated through-hole pads 0.015" larger than drill and therefore large enough to avoid breakout? Leave Plenty of Breadcrumbs for Your Fabricator Fabricator notes can make the difference between a quick turn and a protracted delay. If file names are just a jumble of numbers or it is unclear about what services are required, the notes are where we can go for guidance. • Will the fab notes conflict with your order form? • Do notes call for unnecessary services? • Do you reference documents that the fabricator does not have access to? • Does the design service you selected include a technician checking your notes? Not all quick turn prototyping services offer human intervention. So, if you chose to con- vert to Gerber, please invest a few minutes in your design and check your files before you engage your manufacturing partner.
