Webb17 aug. 2024 · The finished hole diameter is the recommended hole size for your PCB land pattern – it’s the reduced size when the through-hole is plated. Board manufacturing industries also prefer to get the finished hole diameter and they’ll be able to determine which drill bit to use. Through Hole Wave vs. Through Hole Reflow WebbPlated-through slots, also called PTH slits (PTH = plated through hole), plated elongated holes , plated-through milling or PTH routing, are producible from 0,6mm width. Smaller diameters are enlarged to 0,6 mm in diameter. Not only circular drills can be plated, but also various geometric shapes, including larger cut-outs.
