Abstract
A method of quantitatively measuring the adhesive strength of a cover sheet of an electronic component housing container including a main body having multiple housing recesses in a longitudinal direction and a cover sheet peelably adhered to the main body. The method includes mounting the housing container on a carrier plate by fitting the housing recesses in one or more housing holes of the carrier plate which includes a plate body having the one or more housing holes in the longitudinal direction and multiple sprocket holes spaced apart from the housing holes in a width direction and arranged at regular intervals in the longitudinal direction; engaging some tooth tips of a sprocket in the sprocket holes; and peeling the cover sheet from the main body by rotating the sprocket using the width direction as an axis to move the carrier plate in the longitudinal direction.
