Material Positioning<\/div>\n

A stable glass base for silicon devices, microstructures and optical windows<\/h2>\n

Material selection starts from thermal matching, surface quality, thickness consistency and the bonding process, and is then translated into inspectable drawing requirements.<\/p>\n<\/div>\n

PYREX\u00ae Micro-Electro is a borosilicate glass intended for microelectronic and wafer-level applications, suited to projects needing glass\u2013silicon thermal matching, optical windows, electrical insulation or package lids.<\/p>\n

What usually affects delivery is not the material name itself but thickness, TTV, warpage, edge quality, surface cleanliness and packaging. We assess these against the drawing together with cutting, lapping, polishing, cleaning and inspection.<\/p>\n
