description[en] = <b>4 Layer Minimum Rules for JLCPCB</b>\n<p>\nThese are the minimums <a href="https://jlcpcb.com/capabilities/Capabilities">quoted by JLCPCB</a> to produce a 4-layer PCB design rules. These rules are "free" and generally low-cost. There is one DRC set that is smaller (see MicroMod rules) but boards designed with these rules should pass review without question.\n<ul>\n<li>4 Layer</li>\n<li>5mil Trace/Space</li>\n<li>5mil Annular Rings</li>\n<li>0.2mm/7.9mil Vias</li>\n<li>2.5mil Stop Mask</li>\n</ul>
