Abstract
A method for cleaning and coating a tip of a test probe in an integrated circuit package test system is provided. The method includes 1) saturating a brush tip comprising nonporous bristles with a solution of phosphonic acid; 2) applying the solution of phosphonic acid to the tip of the test probe with the brush tip to coat the tip of the test probe with the solution of phosphonic acid; and 3) allowing the solution of phosphonic acid to dry on the tip of the test probe and form a self-assembled monolayer of phosphonates thereon.

A method of cleaning and coating a tip of a test probe in a test system for an integrated circuit package, said method comprising 1) saturating a brush tip comprising metal bristles with a solution of phosphonic acid;
- 2) applying the solution of phosphonic acid to the tip of the test probe with the brush tip to coat the tip of the test probe with the solution of phosphonic acid;
- and 3) allowing the solution of phosphonic acid to dry on the tip of the test probe and form a self-assembled monolayer of phosphonates thereon;
- wherein the phosphonic acid is dissolved or dispersed in an alcohol having 1 to 4 carbon atoms, hexane, isooctane, decane, an ether, a dialkylether, a perfluorinated compound, or an aqueous alkaline solution of sodium and/or potassium hydroxide.
