\"\"This product is a custom sapphire substrate with TGV structures<\/strong>, manufactured through precision cutting, drilling, polishing and micro-pattern processing. The through holes can be arranged as single vias, dense via arrays, functional openings or special patterns depending on the device design.<\/p>\n

Compared with standard glass substrates, sapphire offers better scratch resistance, stronger mechanical durability and higher dimensional stability. It is especially suitable for demanding environments where the substrate must remain transparent, clean, stable and resistant to heat or chemical exposure.<\/p>\n

We support customized production based on drawings, including round sapphire wafers, square sapphire plates, rectangular substrates and special-shaped sapphire parts.<\/p>\n
