Abstract
An improvement in adhesive backed carrier tapes where the adhesion is substantially reduced by using a UV-sensitive adhesive tape which can be irradiated to reduce the adhesion within the compartment where each device will be placed. By reducing the initial aggressive adhesion levels minimally sufficient to retain devices securely as placed, the requirement for a lift pin or pushup pin to assist in removing the component can be eliminated. The principal benefits include substantial increase in throughputs and yields accompanied by proportionate cost reduction benefits.
