Abstract: A position calibration system and method are disclosed, in which a control unit is provided to control a positioner sensing module to scan a circular positioner provided on a positioning substrate in a first direction and a second direction so as to acquire midpoints of two scanned line segments and acquire an intersection of lines extending from the two center points in a direction perpendicular to the first and the second directions as a calibration reference point, which correspond to a centroid (a center) of the circular positioner. The calibration reference point functions as a reference point for positioning the positioning substrate with respect to the positioner sensing module and is stored in a memory unit. The calibration reference point can be used as a positioning point during installation of a machine and can also be used for calibration of a position of the machine.

Abstract: A phase-change temperature regulating system and an electronic device testing apparatus and method are described. In an embodiment, the system uses a temperature regulating fluid chamber containing a temperature regulating fluid to allow the temperature regulating fluid to cover at least a part of at least one surface of an electronic component. When a temperature of the electronic component reaches a boiling point of the temperature regulating fluid, the temperature regulating fluid becomes steam through a phase change to transfer heat energy outward from the electronic component, and condenses on an inner surface of the fluid chamber to further transfer heat energy of the steam to a temperature-regulating apparatus. The condensed temperature regulating fluid flows back to the temperature regulating fluid, thereby continuously circulating.
