METHOD OF DETECTION OF SURFACE FLAWS IN CERAMIC MATERIALS CONTAINING GLASS

摘要

Purpose: The invention relates to nondestructive testing of products and can be used for manufacturing quality control and adjustment process in the production of ceramic-metal connection plates for IC packages and electronics products. SUMMARY OF THE INVENTION: On the surface of unsintered ceramic boards applied fonoobrazuyuschee substance composed of particles of refractory metal a layer thickness of from 0.1 to 300 microns, whereupon sintering was carried out, followed by exhibiting fonoobrazuyuschego substance by selective dissolution speksheys film to about Elena negative image defect or by oxidation in air. Further analysis carried out structure of the defect, its marking. 2 ZP f-ly. (LS
