A leadframe carrier and insert compatible with a temperature-affectable, expandable and contractable leadframe strip to be bonded with a selected plurality of semiconductor chips, said carrier being automatically separable and removable with regard to said insert during manufacture despite possible clinging which may be induced by the expansion and contraction of said carrier insert.

Universal leadframe carrier

Uniform leadframe carrier

Improved leadframe and method for the insert molding of semiconductor components or the like. A plurality of leads separated by zero-flash tab means for controlling the flash during molding are formed in a single sheet of material. The zero-flash tab means are stamped from the stock sheet and then reinserted into the area between adjacent leads. The zero-flash tab means desirably comprise a ridge section for strength and facilitating removal after the molding operation.

Leadframe for flash-free insert molding and method therefor

An apparatus for removing selected integrated circuit dice from a wafer array of dice sequentially moves a striker above a tape to the underside of which the array is mounted and then knocks a die down from the array of dice into a receptacle for transport to further processing stages.

Chip selection in automatic assembly of integrated circuit

A method of forming leadframes for use in manufacturing semiconductor chips starts with fabricating a plurality of leadframes by metal stamping or etching leadframe patterns into a flat ribbon of conductive material. The leadframe patterns include a plurality of outwardly radiating leads, inner radiating leads, and a central perimeter for interconnecting the outwardly and inner radiating leads. The outwardly radiating leads are arranged in groups, each of which are directed along planar perpedicular coordinates. The inner radiating leads have 180 degrees turns in the plane of the leadframe. The inner radiating leads are then successively bent at an acute angle and parallel to the plane of said leadframe so that the inner radiating leads are offset from the plane of the leadframe. The bending is performed in such a manner that each of the leads are formed with a stable spring force for effective bonding to corresponding semiconductor chip pads.

A leadframe for an integrated circuit includes a set of individual leads temporarily connected in an array; each lead having an exterior portion shaped in a standard form and an interior portion shaped to form a standard array of contacts and to have the same spring constant for deflections perpendicular to the plane of the leadframe.
