METHOD AND DEVICE FOR INSPECTING SOLDER MATERIAL, CONTROL PROGRAM, AND COMPUTER READABLE RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a device and method capable of measuring the viscocity of a solder material in a short time without generating deterioration of the solder material.

SOLUTION: A infrared spectroscopic measurement part 10 detects a first intensity of an infrared ray having a specific wavenumber reflected from a solder material which is an inspection object by irradiating the solder material which is the inspection object with light, and a second intensity of the infrared ray having the specific wavenumber reflected from a solder material which is a comparison object by irradiating the solder material which is the comparison object with the light. Then, the viscocity of the solder material which is the inspection object is calculated by sustituting the first infrared absorbance for a calibration curve equation specified based on the second infrared absorbance in a calculation part 40.
