WG TECH Co., Ltd. (603773.SS): Mission and Values

• Two wholly owned operating subsidiaries: Hubei Tongge Microcircuit and Jiangxi Dehong, each focused on glass-related substrate and component technologies.
• Hubei Tongge Microcircuit: specializes in glass-based TGV (Through-Glass Via) multilayer PCBs and optical devices that meet requirements for advanced semiconductor packaging, high-frequency and miniaturized interconnects.
• Jiangxi Dehong: focuses on high-uniformity glass substrates for Mini LED backplanes and mass-transfer carrier plates, serving the growing large-size TV and high-brightness display segments.
• Vertically integrated operations: raw glass processing → photolithography/laser via formation → multilayer lamination and metallization → testing and final assembly, enabling tighter process control and traceability.
• Heavy R&D orientation: continuous process development (TGV yield, glass thinning, laser drilling precision), materials science (coatings, AR films) and equipment integration to maintain a technology lead.
• Commercial partnerships and integration: supplies modules and substrates to consumer-electronics OEMs (including collaborations with Hisense) and to advanced packaging houses in China and overseas.

• Product sales: glass substrates for Mini LED panels, TGV multilayer glass PCBs, optical windows and carrier plates make up the bulk of revenue.
• Custom engineering and integration services: development of customer-specific substrate stacks, optical coatings and assembly-ready modules.
• Capacity and equipment sales/upgrade services: aftermarket support for substrate handling and precision laser drilling tools.
• Intellectual property and process licensing: select transfer of proprietary process know-how to partner fabs under commercial agreements.

• Investment focus: yield improvement for TGV fabrication, glass thinning consistency (<50 µm targets), laser precision (micron-scale via positioning), and anti-reflective/anti-scratch optical coatings for TV and mobile displays.
• Laboratory and pilot lines: in-house pilot fabs allow rapid iteration from process development to mass production-reducing qualification cycles for major customers.
• IP portfolio: method patents for through-glass vias, multilayer lamination techniques, and substrate surface treatments that support premium pricing and higher gross margins versus commodity glass suppliers.

• Vertical integration: control from raw glass procurement and substrate cutting to metallization, inspection and final delivery, lowering dependency on third-party fabricators and improving quality yield.
• Supplier diversification: mixes domestic and imported high-grade optical glass and specialty chemicals to balance cost and performance.
• Quality systems: inline metrology and statistical process control (SPC) to maintain high yields required by large-format Mini LED TV panels and semiconductor packaging clients.

• Higher ASPs for precision glass TGV and Mini LED carrier plates compared with generic glass due to added processing steps and qualification premium.
• Margin uplift from proprietary process steps (laser drilling, multilayer lamination) and from value-added services (custom engineering, testing certification).
• Scale effects: fixed-cost absorption across growing production volumes, with targeted capex to expand glass substrate capacity in line with Mini LED and advanced packaging demand.

• Close collaboration with consumer electronics brands (e.g., Hisense) to co-develop substrate specifications and ensure timely integration into production lines.
• Target markets: large-size Mini LED TVs, high-density display modules, and advanced semiconductor packaging requiring glass interposers/PCBs.
