High-temperature Electrical Insulations for Egs Downhole Equipment
The development of highly reliable downhole equipment is an essential element in enabling the widespread utilization of Enhanced Geothermal Systems (EGS). The equipment used in these systems is required to operate at high voltages and temperatures on the order of 200 to 250°C (and eventually to 300 ̊C). These conditions exceed the practical operating ranges of currently available thermoplastic w...
متن کاملPlastic Package Moisture-Induced Cracking
With the older “through-hole” technology packages such as the Dual In-line Package (DIP), soldering to printed circuit boards was accomplished using a wave solder. The DIP leads went through holes in the printed circuit board, where they were exposed to molten solder during the mounting process. The DIP’s body was never subjected directly to the solder melt, because it was protected from the he...

متن کاملOF PACKAGE I / O LEAD ELECTRICAL PARASITICS FOR DIFFERENT PACKAGES Electrical Parameters Wire - bonding Package Type
This paper is concerned with the analysis and optimization of the ground bounce in digital CMOS circuits. First, an analytical method for calculating the ground bounce is presented. The proposed method relies on accurate models of the short-channel MOS device and the chip-package interface parasitics. Next the effect of ground bounce on the propagation delay and the optimum tapering factor of a...
