Abstract
An improved continuous adhesive backed carrier tape which eliminates the need for a lift pin to assist in removing components from the compartments in the carrier tape within which the components are adhesively retained. The improvements are achieved by utilizing a strip of continuous length containing a low tack adhesive coating within the central portion of the plastic strip located to underlie the entire bottom of each carrier tape compartment when the strip is affixed there to by either aggressive adhesive rails or by mechanical means, such as ultra sonic bonding. The unique feature is to affix low tack adhesive means underneath the compartment area of the carrier tape, sufficient to retain small, lightweight components yet an adhesion level that is low enough to enable the component to be removed using conventional vacuum pick tools without lift pin assistance.
