Abstract: Systems and methods are disclosed that may include identifying a first coefficient of thermal expansion for a first component, the first component including component pins having a first pitch value; identifying a second coefficient of thermal expansion for a second component, the second component associated with electrically conductive pads; determining a relative expansion value based on the first coefficient of thermal expansion and the second coefficient of thermal expansion; determining a change in temperature value of the first component and the second component, the change in temperature value indicating a change in temperature caused by a soldering process; and determining a second pitch value for the electrically conductive pads based on a product of the relative expansion value, the first pitch value, and the change in temperature value, the second pitch value causing an alignment between the component pins and the electrically conductive pads during the soldering process.

Abstract: A chassis having a cover moveable between open and closed positions and circuitry for detecting whether the cover is in the open or the closed position. The circuitry includes a transmitter of optical energy disposed at a fixed position within the chassis for transmitting pulses of optical energy at a predetermined frequency and a receiver for optical energy disposed at a fixed position within the chassis. A reflector is mounted to an inner surface of the cover and is disposed in a path to intercept and then reflect the intercepted transmitted energy to the receiver when the cover is moved to the closed position and being disposed away from the path to prevent the transmitted energy to be intercepted and then reflected to the receiver when the cover is moved to the open position.
