    摘要: A semiconductor chip mounting component includes a support structure adapted to engage a semiconductor chip. The support structure has a top surface, a bottom surface, and a gap extending through the support structure for defining first and second portions of the support structure on opposite sides of the gap. The support structure includes at least one elongated bus disposed alongside the gap, on the second portion of the support structure. The support structure includes a plurality of electrically conductive leads, each lead having a connection section extending across the gap, the connection section having a first end disposed on the first portion of the support structure, and a second end secured to the bus. Each lead includes a frangible section disposed between the first and second ends of the connection section, the frangible section having a cross-sectional area that is smaller than a cross-sectional area of the connection section. The gap is open at the bottom surface of the support structure. A semiconductor chip is disposed beneath the bottom surface of the support structure. The leads are adapted to be bonded to contacts on the semiconductor chip by breaking the frangible sections of the leads so as to disconnect the second ends of the leads from the bus and engage the leads with the contacts of the semiconductor chip.
