Abstract
The present application describes a through-hole component insulator and assembly process which has the advantages of preventing solder from contacting the metal case of a through-hole component without an addition step or additional material from the standard fabrication process for a printed circuit board. The printed circuit board of the present invention includes a printed ink spacer disposed beneath the through-hole component wherein the printed ink spacer is included with a standard silk-screen artwork layer in the printed circuit board design stage. The printed ink spacer raises the through-hole component from the printed circuit board surface to prevent solder from contacting the metal case of the through-hole component during the printed circuit board soldering stage. Using a silk-screen artwork layer which includes at least one printed ink spacer in the artwork, the printed ink spacer is deposited during deposition of a standard printed design on the printed circuit board fabrication.
