A method for improving heat dissipation in an encapsulated electronic package usually referred to as a chip-size SAW package. The package comprises one or more acoustic-wave components fabricated on a die, which is disposed on an electrically non-conductive carrier separated by electrically conducting bumps. The top of the package is covered by a laminate and a hermetic seal layer. Heat dissipation can be improved by removing a part of the laminate and then depositing a layer of thermal conducting material on the package, and by providing one or more heat conducting paths through the carrier.

The invention is directed to a method of bonding a hermetically sealed electronics package to an electrode or a flexible circuit and the resulting electronics package, that is suitable for implantation in living tissue, such as for a retinal or cortical electrode array to enable restoration of sight to certain non-sighted individuals.

Electrically powered electromagnetic field source beacons installed in a reference well in combination with a down-hole measurement while drilling (MWD) electronic survey instrument near the drill bit in the borehole being drilled permit distance and direction measurements for drilling guidance. Each magnetic field source beacon consists of a coil of wire wound on a steel coupling between two lengths of steel tubing in the reference well, and powered by an electronic package. Control circuitry in the electronic package continuously “listens” for, and recognizes, a “start” signal that is initiated by the driller. After a “start” signal has been received, the beacon is energized for a short time interval during which an electromagnetic field is generated, which is measured by the MWD apparatus. The generated magnetic field may be an AC field, or switching circuitry can periodically reverse the direction of a generated DC electromagnetic field, and the measured vector components of the electromagnetic field are used to determine the relative location coordinates of the drilling bit and the beacon using well-known mathematical methods. The magnetic field source and powering electronic packages may be integral parts of the reference well casing or may be part of a temporary work string installed therein. Generally, numerous beacons will be installed along the length of the reference well, particularly in the important oil field application of drilling steam assisted gravity drainage (SAGD) well pairs.

A method for determining full chip leakage power first estimates leakage power and dynamic power for each circuit macro. The power supply voltage to each macro is first assumed to be nominal. The power dissipation for each macro is modeled as a current source whose value is the estimated power divided by the nominal power supply voltage. The power distribution network is modeled as a resistive grids. The thermal environment of the IC and its electronic package are modeled as multi dimensional grids of thermal elements. Algebraic multi-grid (AMG) methods are used to calculate updated circuit macro voltages and temperatures. The macro voltages and temperatures are updated and updated leakage and dynamic power dissipation are calculated. Iterations are continued until leakage power converges to a final value.
