Los Angeles is not just the entertainment capital of the world; it is the heart of the "Aerospace Corridor" and "Silicon Beach." From the high-tech clusters in El Segundo and Long Beach to the satellite manufacturing hubs in the South Bay, the demand for ultra-reliable electronic packaging is unprecedented. Kovar (ASTM F15 / 4J29), a nickel-cobalt-iron alloy, serves as the cornerstone for these industries.
Why Kovar? For companies like SpaceX, Northrop Grumman, and Raytheon, hermetic sealing is non-negotiable. Kovar's thermal expansion characteristics match those of borosilicate (hard) glass and alumina ceramics, ensuring that electronic components remain sealed against vacuum and extreme temperatures in space and defense applications. As a leading manufacturer, we provide the Los Angeles market with the precision-engineered Kovar package shells required for high-frequency RF connectors, microwave packages, and laser diodes.
Founded in November 2014, Xinyunyang has adhered to the principles of Integrity, Innovation, Cooperation, and Sharing. We specialize in Kovar precision processing technology, serving global sectors including semiconductors, optical communications, aerospace, medical devices, and the military industry.
High-precision processing capability Advanced technology and equipment Strict quality control Flexible customized servicesOur workforce of over 100 professionals includes 30% technical engineers dedicated to solving complex material challenges for 4J29 Kovar and titanium alloys.
With over a decade in precision metal processing, we are proactively laying out cutting-edge packaging solutions for 5G, AI, and New Energy sectors.
Our ISO 9001 certified quality management and intelligent scheduling system ensure 15%-20% faster delivery than industry standards.
In the current global economic landscape, Los Angeles-based procurement teams are looking for "Value-Add" and "Information Gain" in their supply chain. Our China-based factory offers a unique synergy of cost-efficiency and high-tier engineering.
By leveraging China's mature industrial ecosystem for raw 4J29 Kovar and high-end CNC equipment, we offer high-precision shells at a price point that empowers LA startups to scale their prototypes into mass production without budget exhaustion.
Kovar requires specific plating—typically Nickel or Gold—to prevent oxidation and enhance solderability. Our in-house processes meet stringent RoHS and military standards (RG Connectors), ensuring long-term reliability in corrosive environments.
Whether it’s a small-batch run for a Silicon Beach medical device startup or high-volume shells for a Burbank-based telecommunications giant, our flexible manufacturing allows for "Miniaturized" and "Customized" designs that off-the-shelf suppliers cannot match.
The transition to 6G, the rise of Quantum Computing in Caltech-affiliated labs, and the miniaturization of medical implants are driving the next wave of Kovar applications. We are seeing a move towards "Micro-Hermeticity"—the ability to seal chips at the wafer level or in ultra-small packages (mm-scale).
From prototype to high-volume production, our factory is ready to serve the Los Angeles market with unparalleled precision.
