"SpletThis leads you to what we call routing. This process of routing a printed circuit board (PCB) needs more of tolerance compared to drilling. Furthermore, if the circuit board design requires 0.250” plated hole that is finished, a router will have to cut a 0.256” diameter open for the plated hole. This will have a preferred tolerance of +/-0.005. " - Pcb hole tolerance
