摘要:
A die pad (108) with a punched hole providing a throughway (110) is affixed upon the chip carrier base 100. Such throughway permits the electronic interconnection of the die backside (112) to a conductive runner (104) by electrically conductive material (110) set between the die backside (112) and the conductive runner (104).
