Abstract

Lead inductances of a 432-lead TCP (Tape Carrier Package) with a metal cap are evaluated by treating the leads as multiconductor-coupled lines. A useful inductance evaluating method is obtained by using a quasi-TEM electromagnetic field analysis and matrix operations. This method is demonstrated for the TCP. By a proximity effect of grounded conductors, the effective self inductance of the longest lead can be reduced to 7.3 nH. This result indicates that TCP's can be applied to high-speed LSI's of clock rates up to 100 MHz. >
