Printed Circuit Design Tutorial (C. Define Non-plated holes- NPTH)

    C. Define Non-plated holes(NPTH)

    There are several ways to define the non-plated holes in the PCB.

•             1) You can define certain hole size to be u sed as non-plated holes. For example you can define all 40mil holes in your design to be non-plated, and tell the PCB house you want all 40mil hole to be NPTH

•             2) You can generate separate NC drill files for NPTH holes.

•             3) The most professional way is to generate a draw chart as shown in Fig 10.
