Embodiment Construction

[0035] image 3 Shown is an annular element carrier in the form of a soft metal coil of stainless steel or other high strength metal that is about 0.13 millimeters (0.005 inches) thick and about 6.1 centimeters (2.0 inches) wide. The web 50 is an "endless" type of web in which the web has no beginning or end, but is movable around a series of pulleys and sprockets between the various processing stations, e.g. Described in US Patent No. 5,226,382. The web 50 is bounded by spaced apart side edges 52 and 54 that are parallel to each other and includes a series of guide or sprocket holes 56 that serve as drive perforations to accommodate drive sprockets (not shown). drive stubs. The sprocket holes 56 are arranged adjacent to at least one of the side edges 52 and 54, and preferably both of the side edges 52 and 54, and are evenly spaced along the length of the web 50. . The web 50 shown in FIG. 4 is formed with variously shaped openings into which the mask can be inserted. The ...

Abstract

A laser beam (102) cuts through a component carrier mask (96) made of thin elastomeric material such as silicone rubber to form slots (98) having slot openings of a desired shape. In a preferred embodiment, a light absorptivity enhancement material such as iron oxide introduced into the silicone rubber causes formation of a flexible support blank that operationally adequately absorbs light within a light absorption wavelength range. A beam positioner (106) receiving commands from a programmed controller causes a UV laser beam of a wavelength that is within the light absorption wavelength range to cut into the mask multiple slots with repeatable, precise dimensions. Each of the slots cut has opposed side margins that define between them a slot opening of suitable shape to receive a miniature component (10) and to exert on it optimal holding and release forces.
