A metal mask provided with a slit, and a resin mask that is positioned on a front surface of the metal mask and has openings corresponding to a pattern to be produced by vapor deposition arranged by lengthwise and crosswise in a plurality of rows, are stacked.

Inspection device and method for inspecting an adhesive pattern on a substrate
11511531 · 2022-11-29 · ·

Inspection devices and methods for inspecting an adhesive pattern on a substrate are disclosed. The inspection device includes at least one sensor having a heat sensor head for detecting a pattern of the adhesive bead, and a controller. Reference data representing a desired adhesive pattern is initially provided to a controller. A predetermined tolerance range for the desired adhesive pattern is also provided to the controller. An adhesive bead is discharged onto a substrate from a nozzle. A pattern of the discharged adhesive bead is then detected by the sensor when the substrate moves. Signals representing the detected pattern are received from the sensor at the controller. Finally, the signals representing the detected adhesive pattern are compared to the tolerance range of the desired adhesive pattern.
