🛠️ Technical Deep Dive
- Through-Glass Via (TGV) technology utilizes laser drilling and chemical etching to create high-aspect-ratio holes for vertical electrical connections.
- Multilayer Redistribution Layers (RDL) are deposited on the glass surface to facilitate fine-pitch routing, significantly reducing signal loss compared to organic alternatives.
- Glass substrates exhibit a Coefficient of Thermal Expansion (CTE) that is more closely matched to silicon, reducing warpage during the thermal cycling of high-power chips.
- The manufacturing process involves specialized handling equipment to manage glass panels, which are prone to edge chipping and micro-cracking during traditional pick-and-place operations.
