Latest Patents
Trammell's patent, titled "Offset bending of curvaceously planar radiating leadframe leads," outlines a method for forming leadframes used in semiconductor chip manufacturing. The process begins with fabricating multiple leadframes through metal stamping or etching patterns into a flat ribbon of conductive material. These leadframe patterns consist of outwardly radiating leads, inner radiating leads, and a central perimeter that interconnects them. The design includes groups of outwardly radiating leads directed along planar perpendicular coordinates, while the inner radiating leads feature 180-degree turns in the plane of the leadframe. Trammell's method involves bending the inner radiating leads at an acute angle, offsetting them from the plane of the leadframe. This bending technique ensures that each lead is formed with a stable spring force, facilitating effective bonding to corresponding semiconductor chip pads.
