描述
Our custom through-via sapphire substrates are manufactured from high-quality single crystal sapphire and processed according to customer drawings. The substrate can be made with round via holes, micro hole arrays, square windows, cavities, slots, and special patterns.
The via structure can be used for vertical interconnection design, optical transmission, device alignment, packaging integration, sensor structure formation, and functional micro-device development. Different hole sizes, hole pitches, via quantities, substrate thicknesses, and external shapes can be customized to meet specific project requirements.
Sapphire is especially suitable for demanding environments where the substrate must maintain high strength, stable geometry, good transparency, and resistance to heat, chemicals, and mechanical wear.

คำถามที่พบบ่อย
Q1: Is this a standard glass TGV substrate?
No. This product is made from sapphire. It uses TGV-style through-via structures, but the substrate material is single crystal sapphire, not ordinary glass.
Q2: Can sapphire be processed with micro via holes?
Yes. Sapphire can be laser processed or precision machined to form micro holes, through vias, hole arrays, square openings, and other custom patterns.
Q3: What shapes are available?
We can supply round sapphire wafers, square plates, rectangular substrates, and custom-shaped sapphire parts.
Q4: Can you make both holes and square windows on the same substrate?
Yes. Different structures, such as circular holes, square windows, cavities, slots, and alignment holes, can be combined according to the drawing.
Q5: Do you support prototype orders?
Yes. Prototype and small-batch production are available for R&D, testing, and design verification.
