Method and fixture for laser bar facet coating

Abstract

A method and fixture for laser bar facet coating are disclosed. A holder for securing devices having surfaces for coating includes first and second channels. A plurality of web slats are received in the channels. The web slats have first and second ends and first and second device engaging surfaces. The ends of the web slats are received in respective channels. The ends of the web slats cooperate with the ends of adjacent web slats. The web slats are secured at one end of the channels and otherwise are movable along the channels between an open position to receive devices therebetween for coating and a closed position in which edges of the web slats engage the devices received therebetween for coating. A bias member may be used to retain the web slats in the closed position gripping the devices for coating. In another embodiment, the invention provides a method for coating surfaces of substantially parallelepiped devices. The method includes securing at least one parallelepiped device between a pair of device engaging surfaces in a holder, mounting the holder in a vacuum chamber, and establishing a surface coating environment in the vacuum chamber.
