Webmetalized holes must to be drilled wider in order to accept the metal layer and still to be wider than the lead. Talk with your PCB maker about this. For not metalized holes, simply add 0.1mm to the lead diameter. Note that too big clearances will reduce the reliability of the PCB, because the solder has pretty bad mechanical properties. WebFeb 21, 2024 · Neck down is the process of shrinking the PCB trace width to a smaller width within the rule constraints to allow for trace routing in tight clearances. Typically, neck-down is the percentage width change of pad size to a track width size. However, it is also possible to set a size reduction from track-to-track as it enters or leaves an area. WebThe finished hole to copper clearance will be the drill to copper clearance along with the copper plating thickness. Finished hole to copper clearance = drill to copper clearance + plating thickness x 2. If the drill diameter is 6 mil and the plating thickness is 1 mil, then: finished hole to copper clearance = 6 + 1 x 2 = 8 mil. gracewell healthcare uk
