An authoritative metallurgical analysis of Glass-to-Metal Seal (GTMS) interfaces, expansion chemistry, and high-vacuum environmental performance.
In high-reliability hermetic packaging, structural integrity depends on matching the Coefficient of Thermal Expansion (CTE) of the structural metallic shell with the glass insulation block. Kovar (an iron-nickel-cobalt alloy, ASTM F15 / DIN 1.3981 / UNS K94610 / 4J29) is formulated to display an expansion curve that aligns with borosilicate glasses (such as Corning 7052 or Schott 8250) across a temperature range spanning from sub-zero temperatures up to the glass transformation point (approx. 450°C).
If standard steel or copper were utilized, the vast CTE divergence would induce catastrophic mechanical stresses at the glass interface during cooling, leading to radial micro-cracking and loss of hermetic containment. Standard Kovar matches the CTE of borosilicate glass at approximately 5.0 × 10⁻⁶/°C, maintaining a stable molecular structure during thermal cycling.
The chemical bond between Kovar and borosilicate glass is not merely mechanical; it is chemical. Achieving a vacuum-tight hermetic joint requires a precise oxide layer grown on the Kovar substrate prior to the sealing cycle:
If the oxide layer is too thin, the glass directly contacts raw metal, resulting in poor adhesion and a weak seal. If it is too thick, the excess oxide layer can shear under thermal stress, creating a leak path. At Xinyunyang, this oxide thickness is monitored using metallurgical cross-sections to ensure reliable performance.
Procuring hermetic solutions on a global scale requires strict adherence to international quality standards. Procurement departments evaluate glass-to-metal sealing manufacturers based on three major factors:
Raw Material Authentication: Premium Kovar must be sourced from suppliers with tight control over trace elements like phosphorus, sulfur, and carbon, which can affect the stability of the oxide layer. Xinyunyang uses verified ASTM F15 material with complete mill certification.
Plating Integrity: Gold and nickel plating must withstand high temperature brazing without blistering or forming intermetallic voids. Our plating lines adhere to MIL-G-45204 and AMS2404 parameters to maintain solderability and corrosion resistance.
How Xinyunyang plans to address the next generation of extreme-frequency hermetic packaging.
Integrating green manufacturing methods to minimize fluid consumption during CNC machining. Implementing high-efficiency recycling for nickel-cobalt alloys to support ESG compliance for global supply chains.
Developing low-loss dielectric glass formulations coupled with micro-machined Kovar packaging to support transmission frequencies exceeding 100 GHz, with minimized signal attenuation.
Combining metal 3D printing of grade 4J29 architectures with high-precision post-processing CNC milling. This allows for complex cooling channels within the hermetic housing, optimizing thermal management in compact power electronics.
Inside Xinyunyang's manufacturing plant: production lines, quality inspection, and advanced equipment.
