Abstract:
A device comprising:a lead frame bearer strip having longitudinal and lateral directions and a predetermined number of electronic components arranged thereon in at least two parallel longitudinal rows in said longitudinal direction and in parallel lateral rows in said lateral direction;wherein, components along any lateral row perpendicular to the longitudinal direction have the same spacing between them and components along the longitudinal direction have the same allocated spacing within which the components fit,the components have lateral and longitudinal edges and the components are arranged with their lateral edges aligned parallel to the longitudinal rows and longitudinal edges aligned parallel to the lateral rows, andthe components are separated in the longitudinal direction of the bearer strip by alternating first and second spacings, and every second spacing between the components in the longitudinal direction is sufficiently larger than the first spacings to allow for the single-sided supply of free flowing plastic molding compound from a lateral side of the bearer strip onto a corresponding mold between adjacent components straddling said second spacing.
