Piggy-back method of packaging integrated circuits will increase packaging density and design flexibility. It will also eliminate interconnection leads between the die and associated inductances, and thus increase the attainable frequency response of the circuit.
Active RC network is capable of extremely high Q performance with exceptional stability and has independently adjustable zeros and poles. The circuit consists of two integrators and two summers that are interconnected to produce a complete second-order numerator and a second-order denominator.
Molecular flow gas analysis with pulsed vacuum networks of interconnected volumes
CdS thin film solar cells series and parallel interconnection into modules, using soldered or conductive epoxy bonding methods
Optimizing bearing length and permissible axis curvature alleviates distortion of film gap of gas lubricated journal bearing in deployment mechanisms. Required bearing length is divided into two shorter bearings interconnected by links which allow satisfactory conformity with the bent, load-carrying member.
Technique for packaging electronic modules interconnects integrated circuits and discrete components by means of beryllium-copper strips in a molded diallyphthalate tray. Simple girder-like construction provides ease of assembly, high rigidity, excellent vibration resistance, and good heat dissipation characteristics.
Fabrication process improves the size ratio and shape factor of the base region of self-isolating transistor arrays. Basic processing steps in the modified method include, sub-diffusion, epitaxial layer growth, isolation-diffusions, enhancement diffusions, aluminum interconnect deposition, and testing and packaging.
