Abstract
Electrostatic-discharge safe devices for processing electronic components, e.g., matrix trays, chip trays, and wafer carriers are disclosed that are made from a mixture of a high temperature, high strength polymer and at least one metal oxide, and optionally with at least one pigment. The use of the metal oxides as conductive materials advantageously allows for light-colored electrostatic-discharge safe materials to be made. Such materials may be colored with pigments without compromise of material performance specifications.
Claims18
An article for receiving electronic components, the article comprising:
- a structure comprising at least one electrostatic discharge-safe surface for contacting and supporting an electronic component, wherein the structure comprises a mixture of polyetheretherketone and conductive antimony doped tin oxide present in a concentration of about 40% to about 75% by weight to provide, at the electrostatic discharge-safe surface, an electrostatic discharge-safe resistivity in the range of 103 to 1014 ohms per square,
- wherein the structure has, at the electrostatic discharge-safe surface, an L value of more than about 40, and
- wherein the article is a member of the group consisting of a disk cassette, matrix tray, wafer carrier and a chip tray.
A method for processing electronic components, the method comprising
- providing a set of colored carriers for electronic component processing, the set including at least two subsets of colored carriers wherein each colored carrier comprises an electrostatic discharge-safe surface, with each subset comprising a subset color distinct from the other subset colors, wherein the surfaces comprise polyetheretherketone and conductive antimony doped tin oxide present in a concentration of about 40% to about 75% by weight to provide, at the electrostatic discharge-safe surface, a resistivity in the range of 103 to 1014 ohms per square, and a pigrnent contributing to the coloration of the subset color distinct from the other subset colors, and wherein the carrier is a member of the group consisting of a disk cassette, a matrix tray, a chip tray, and a wafer carrier;
- and
- placing an electronic component on the electrostatic discharge-safe surface of one of the colored carriers that is a member of the set of colored carriers.
