Plated Through Hole Diameter at Sharon Boyle blog

Plated Through Hole Diameter. Three possible minimum hole sizes: This article explores pths in depth—from their key benefits like durable interlayer connections and flexible component placement, to critical design considerations around hole size, spacing, depth. They apply whether the hole is used as a routing. For level a minimum hole size = 0.55mm + 0.25mm = 0.80mm.  — plated through holes (pths) are vital in printed circuit boards for enabling reliable connectivity between layers. For level b minimum hole size = 0.55mm + 0.20mm = 0.75mm.  — if the via is plated up to the minimum under thickness in the hole wall (1 mil), we can now use the class c fabrication allowance to determine the required pad size. For density a, this extra margin is 0.25mm. For a 10 mil drill hole diameter, we would have an 8 mil finished hole size with a minimum pad diameter of 20 mils on all layers. the following terminology is used to describe the various components involved in creating a plated through hole.
