ABSTRACT:
A method for making a printed circuit board with a flush surface land begins by forming a multi-layer printed circuit board with a recess in a surface dielectric layer. Then, a hole is drilled into or through the printed circuit board; the hole communicates with the recess. After the recess is formed, a conductive material is provided in the recess to form a surface land and provided on an inner surface of the hole to form a plated hole which is electrically connected to the surface land. The conductive material in the recess has a thickness substantially equal to a depth of the recess such that the surface land is flush with an adjacent surface of the dielectric surface layer.
