Temperature dependent calibration of movement detection devices

A method of constructing an electronics system comprising:

• constructing a board including:
• forming a thermal conduit on the structural material, the thermal conduit having a thermal heat transfer capacity that is higher than a thermal heat transfer capacity of the structural material and having a first region, a second region, the first and second regions being horizontally spaced, and a connecting portion connecting the first region to the second region;
• forming a thermal interface on the structural material above the first region of the thermal conduit, the thermal interface having an exposed upper surface and a thermal heat transfer capacity conductivity that is higher than the thermal heat transfer capacity of the structural material and being attached to the first region of the thermal conduit;
• mounting an electronics device to the board above the second region of the thermal conduit, the thermal conduit forming a thermal path between the surface of the thermal interface and the electronics device;
• and
• attaching a board interface to the board and electrically connected to the electronics device, the board interface being adapted to interchangeably connect to a calibration computer interface of a calibration station having thermoelectric device for releasably contacting the exposed upper surface, and to connect to a field computer interface that is connected to a field computer.
