  • Method of mounting an electronic power component
    Patent number: 5915754
    Abstract: A method of mounting an electronic power component to a cooling element includes finishing at least a bonding area of the cooling element with a finish for use during soldering, forming an indentation in the bonding area of the cooling element, placing adhesive in the indentation, attaching the power component to the cooling element using the adhesive, and thereafter soldering the power component to the cooling element. The finishing melts during soldering and the adhesive prevents shifting of the power component on the cooling element during soldering. Alternatively, the power component is attached to a printed circuit board by adhesive bonding prior to soldering.

  • Method and apparatus for the measurement of the corrosion potential between a coated metal surface and a reference electrode
    Patent number: 5369370
    Abstract: Method for the investigation of the condition of a corrodible surface coated with a polymer, wherein the corrosion potential at the corrodible surface is measured without contacting either the corrodible surface or the polymer coating by means of a Kelvin probe which measures the potential between the corrodible surface and a probe electrode. The potential difference reflects the corrosion potential and, thus, the corrosion condition of the polymer coated surface.
