Explore our elite line of hermetic products engineered to meet the stringent demands of global standards and optimized for Costa Rican industrial ecosystems.
Costa Rica has evolved from an agricultural exporter into a sophisticated high-tech manufacturing powerhouse, specifically within the fields of advanced medical technology, aerospace systems, and microelectronics. Underpinned by favorable free trade zones such as the Coyol Free Zone in Alajuela and the Cartago Park, Costa Rica has attracted global original equipment manufacturers (OEMs). To sustain this rapid growth, local assemblers require high-precision materials that guarantee the reliable shielding of delicate sensors, micro-optics, and micro-electromechanical systems (MEMS).
In these advanced manufacturing scenarios, Kovar (4J29) serves as the paramount standard. This controlled expansion alloy, predominantly comprised of 29% nickel, 17% cobalt, and a balanced composition of iron, is specifically formulated to possess a coefficient of thermal expansion (CTE) that perfectly matches borosilicate glasses (such as Pyrex) and technical ceramic substrates. By establishing an airtight, molecular glass-to-metal seal (GTMS), Kovar package shells insulate critical internal hardware against gas intrusion, moisture absorption, and thermal fluctuations, which is particularly vital for life-critical biomedical implants and orbital avionics assemblies manufactured in Costa Rica.
Kovar (4J29) is a nickel-cobalt-iron alloy that undergoes strict chemical regulation. When heated to high temperatures (specifically between 30°C and 400°C), its linear expansion rate matches that of glass, avoiding cracks, stresses, or catastrophic seal failures. Its chemical and mechanical consistency is regulated by international standards including ASTM F15 and MIL-I-23011.
| Chemical / Physical Characteristic | Composition Percentage / Value | Technical Significance for Sealed Shells |
|---|---|---|
| Nickel (Ni) Content | 28.5% - 29.5% | Maintains low coefficient of expansion and magnetic phase stability. |
| Cobalt (Co) Content | 16.8% - 17.8% | Elevates Curie temperature and refines glass-matching CTE properties. |
| Iron (Fe) Content | Balance (~53%) | Forms the structural matrix, promoting workability and high durability. |
| Thermal Expansion (30°C to 400°C) | 4.6 - 5.2 × 10⁻⁶/K | Directly aligns with hard borosilicate glasses and alumina ceramics. |
| Density | 8.36 g/cm³ | Offers dense, non-porous structure to completely prevent helium leaks. |
| Tensile Strength | 450 - 590 MPa | Excellent strength profile to resist extreme atmospheric pressures. |
A globally trusted manufacturer of hermetic lids, Kovar components, and advanced micro-packaging shells.
Founded in **November 2014**, Xinyunyang Precision Technology Co., Ltd. has established itself as an industry pioneer. From our founding, we have adhered to the business principles of **Integrity, Innovation, Cooperation, and Sharing**. By centering Kovar precision processing technology as our core competitive advantage, we cultivate profound specialization across semiconductors, optical communications, aerospace, medical devices, and new energy/military sectors. Our overarching mission is to deliver miniaturized, custom, and exceptionally reliable metal packaging solutions to global clients, expanding our technological reach deep into the high-precision manufacturing corridors of Costa Rica.
The global market for hermetic packaging is expanding rapidly, driven by the rollout of 5G infrastructure, satellite constellations, and the miniaturization of high-value optical components. Since Kovar maintains a low thermal coefficient matching optical glass, it remains the leading choice for optoelectronic interfaces, laser diodes, and optical transceiver modules. In the global arena, the shift toward sustainable manufacturing and ESG compliance has led to strict regulations, requiring manufacturers to implement strict conflict-free sourcing and RoHS-compliant electroplating methods.
In Costa Rica, these global trends directly impact local free trade zones. With major medical and electronic manufacturing clusters established around Cartago and Heredia, Costa Rican operations depend heavily on responsive supply lines for custom-fabricated Kovar components. The country's strong commitment to sustainable practices makes ESG-validated and green-manufactured Kovar alloy casings highly valuable to local OEMs aiming to meet both technical requirements and strict corporate carbon reduction targets.
We deliver gold-plated, ultra-reliable Kovar housings for pacemakers, surgical tools, and neural stimulators, complying with strict biocompatibility standards for sub-dermal usage.
We manufacture structurally stable Kovar sensor modules that withstand cryogenic and radiation-heavy environments, supporting Costa Rica's orbital aerospace initiatives.
Our hermetic packages shield optical transceivers, ensuring stable performance in high-humidity tropical conditions and protecting against moisture intrusion.
The roadmap for Kovar packaging centers on miniaturization and high-frequency capabilities. As semiconductors shift to higher densities, standard package envelopes are being replaced by micro-machined and wafer-level packages (WLP). This evolution demands tight tolerances that can only be achieved through multi-axis CNC technology and sophisticated chemistry control.
Furthermore, integrating Kovar with high-conductivity materials—such as copper-tungsten (CuW) or direct-bonded copper (DBC)—is becoming a standard practice. These composite designs offer the thermal management capabilities of copper alongside the reliable glass-matching expansion properties of Kovar. Xinyunyang is leading this innovation, ensuring that Costa Rican manufacturers can easily access these advanced engineering solutions.
