Sticking good or bad decision manner of sticking good or bad decision device and tape component of tape component

摘要

PPROBLEM TO BE SOLVED: To determine whether or not a tape member (an ACF or the like) for connecting an electronic component is stuck properly on a substrate surface constituting a liquid crystal display panel or the like. PSOLUTION: Lightness threshold levels Su, Sd are set on an upper part and a lower part between a lightness level of the ACF 4. A CPU 72 extracts binary signals (Fig.4(ab), Fig.4(bb)) from an imaging pattern (Fig.4(aa)) of a glass substrate 2 on which the ACF 4 is stuck properly and an imaging pattern (Fig.4(ba)) of a quality determination object substrate 2 in the stuck state based on the set lightness threshold levels Su, Sd, and determines lamination quality of the tape member (ACF 4) on the glass substrate 2 from the coincidence rate (α) between both shapes.
