Abstract
A method for compensating probe misplacement and a probe apparatus are provided. The method is applicable to a probe module which includes a probe and a fixing base. The probe includes a probe body section and a probe tip section. The probe body section is fixed on the fixing base. The method includes: measuring a temperature of a probe body of the probe body section of the probe; calculating, according to the temperature of the probe body, thermal expansion amount of the probe along a length direction of the probe body section; calculating a compensation value according to the thermal expansion amount; moving the probe or a to-be-tested element according to the calculated compensation value, to align a probe tip of the probe tip section with the to-be-tested element or align the to-be-tested element with the probe tip of the probe tip section.
