Abstract
A substantially planar insulating sheet of high temperature printed circuit board material (11) is used to form a leadframe strip (18, 19, 21) for a semiconductor package (20). The leadframe strip (18, 19, 21) includes a die attach opening (12) through the insulating sheet (11). A plurality of metallized areas (13, 22, 23) on the insulating sheet (11) form bonding pads (13) and package leads (22). Conductive holes (14) electrically connect the bonding pads (13) and the package leads (22).
