Title:
SINTERING CONDITION MONITORING METHOD FOR CERAMIC SUBSTRATE AND ITS DEVICE
Document Type and Number:
Japanese Patent JP3186308
Kind Code:
B2
Abstract:

PURPOSE: To provide a monitoring means for monitoring the sintering condition of a ceramic substrate quantitatively by quantitatively finding a glass amount in a ceramic substrate pattern part.
CONSTITUTION: Following grinding of the surface of a ceramic substrate 1 after sintering, an image, which is detected by an optical system consisting of a light source 3, a sensor 4, a polarizer 5, an analyzer 6, and a group of lenses 10a, 10b, 10c, a half mirror 11, and the like, is processed by an image processing part 7, so that a glass amount in a ceramic substrate pattern part, is found, and subsequently, the glass amount is used as the sintering condition information.
