Honglei Optics Secures Volume Orders for TGV Glass Substrate Direct-Write Lithography Equipment
Honglei Optics has delivered volume orders of its direct-write lithography equipment for TGV glass substrates. Glass substrates show transmission loss of about 0.3dB/mm at 10GHz and dielectric loss more than 50% lower than organic substrates, making them suitable for CPO optical modules, Micro LED, and Chiplet packaging. The industry generally regards 2026 as a critical validation period for glass substrates, with initial commercial adoption expected around 2028.
