Due to the flexible manufacturing processes for producing BGA packages, there has been an explosion of new package designs, many of which contain more than one integrated circuit chip [1]. Existing industry standards for IC package thermal characterization apply only to single-chip packages. This Calculation Corner will present some techniques for calculating the junction … [Read more...]
The Many Flavors of Ball Grid Array Packages
By now, it is a tired truism to say that the consumer electronics industry has consistently delivered on its promise to provide products that are smaller, faster, and more feature-rich at an ever cheaper price. The main driver for these trends has been the increasing integration of more functions on a single chip. In spite of its greater performance, the PC of today has far … [Read more...]
Electronic package characterization per JEDEC standard
Introduction With the increase in power density resulting from advancements insemiconductor packaging technologies comes the issue of heat dissipation. Heatis generated as a result of electrical energy being converted to thermal energyduring circuit activities. The junction temperature of a chip directly affectsthe performance of the circuits and the reliability of … [Read more...]
