Abstract: A thrust bearing cage includes a piloting feature to radially locate a thrust bearing with respect to one of the shafts. Specifically, the bearing cage includes an axial extension at an outer diameter that extends beyond the rollers and around an outer diameter of end of the shaft. This feature permits elimination of a washer.

Abstract: Some embodiments are directed to a method of determining a sintering thermal impedance of a sintering layer by: providing a substrate having a predetermined substrate thermal impedance and disposing the sintering layer on the substrate forming with the sintering layer a stack. Placing at least one semiconductor die, that includes a semiconductor element with at least two element electrodes on the sintering layer. Injecting an electrical current through the at least two element electrodes for measuring a temperature sensitive parameter of the semiconductor element. Heating the stack with a predetermined heat power and determining, while sintering, a semiconductor element temperature from the measured temperature sensitive parameter.

Abstract: A method of determining a sintering thermal impedance of a sintering layer (25) comprising: providing a substrate (20) having a predetermined substrate thermal impedance, disposing the sintering layer (25) on the substrate (20) forming with the sintering layer (25) a stack, placing at least one semiconductor die (30) comprising a semiconductor element (40) with at least two element electrodes (45; 47) on the sintering layer (25), injecting an electrical current through the at least two element electrodes (45; 47) for measuring a temperature sensitive parameter of the semiconductor element (40), heating the stack with a predetermined heat power, determining, while sintering, a semiconductor element temperature from the measured temperature sensitive parameter, measuring a stack temperature, determining a stack thermal impedance by subtracting the semiconductor element temperature from the stack temperature and dividing by the predetermined heat power, and subtracting the predetermined substrate thermal impedan
