Abstract: PURPOSE: A method for inspecting a contact state is provided to improve a reliability of a soldering by selectively re-adhering only a bad location which is obtain by measuring signals from a contact part continuously. CONSTITUTION: A method for inspecting a contact state of a contact portion in a laser soldering comprises the steps of: detecting an infrared ray, transferred against a transfer path of a laser beam, at a predetermined location on an extended line of the transfer path toward the contact portion, wherein the laser beam is generated from the contact portion; converting time and temperature data obtained at the previous step to obtain digital data using the converted time and temperature data; comparing the digital data with predetermined reference data to decipher a contact state of the contact portion; and judging whether or not the contact portion is abnormal.

Abstract: PURPOSE: A method for automatically calibrating a beam transferring distance is provided to calibrate the diameter change according to the laser beam transferring distance and to always keep a regular beam diameter inside the working area of a processor, when manufacturing the laser processor. CONSTITUTION: The calibrating method has the steps of:changing the beam moving direction to as 180 degree as from the first place on a first pass(308) of the beam; reflecting the changed beam to the processed part of the processed object from the second place; and moving the first place to the moving direction of the second place as the distance that is a half of the moving distance of the second place when moving the second place in the certain distance. The method calibrates the diameter change according to the laser beam transferring distance.
