ATG provides an extensive range of standardized and custom-engineered products designed to meet MIL-SPEC and international quality standards. Their product catalog is focused on the physical layer of microelectronics, providing the "housing" that allows chips and circuits to function reliably.
1. Glass-to-Metal Seals
ATGā??s primary product line revolves around glass-to-metal seals (GTMS). These components consist of metal conductors passed through a metal housing, with a specialized glass preform melted to create a hermetic bond between the two.
* Single-Pin Terminals: Used for power and signal transmission in pressurized environments.
* Multi-Pin Headers: Complex arrays of pins used for sophisticated integrated circuits and sensor interfaces.
* Battery Headers: Specialized seals designed for lithium-ion and high-performance battery packs used in aerospace and downhole drilling.
2. Microelectronic Packages
For semiconductor manufacturers, ATG produces high-performance packages that house integrated circuits (ICs) and discrete components.
* TO-Headers (Transistor Outline): A variety of standard TO-style headers (e.g., TO-5, TO-8, TO-39) used for transistors, sensors, and optical devices.
* Flatpacks and Dual-In-Line Packages (DIPs): Hermetic versions of standard chip carriers designed for high-reliability military and space applications.
* Platform Packages: Large-scale hermetic enclosures used for complex hybrid microcircuits.
3. Microwave and RF Packages
As the demand for high-frequency telecommunications grows, ATG has expanded its offerings in the Radio Frequency (RF) and microwave sector.
* SMA/SSMA Connectors: Hermetic versions of standard RF connectors that prevent moisture ingress into microwave assemblies.
* Machined Housings: Precision-machined aluminum or Kovar housings with integrated hermetic seals, optimized for signal clarity and minimal insertion loss.
4. Custom Hermetic Enclosures
Beyond standard catalogs, ATG specializes in "Build-to-Print" services. They work with client engineering teams to develop bespoke enclosures for unique sensor shapes, high-pin-count connectors, or unusual thermal expansion requirements.
Specialized Services and Capabilities
The manufacturing of semiconductors and electrical components requires more than just assembly; it requires rigorous processing and verification. ATG provides several vertically integrated services to ensure the quality of their output.
Precision Machining and Tooling
ATG maintains an in-house CNC machining department capable of working with specialized alloys like Kovar, Inconel, and Monel. This allows the company to produce the metal bodies of their packages with extremely tight tolerances before the glass-sealing process begins.
Advanced Plating Operations
To ensure solderability and corrosion resistance, ATG offers comprehensive plating services. Their facility is equipped to handle:
* Gold Plating: Applied per MIL-G-45204 for high-conductivity and oxidation resistance.
* Nickel Plating: Both electrolytic and electroless nickel plating to provide a durable barrier layer.
* Custom Finishes: Including silver, copper, and tin plating based on specific environmental requirements.
Thermal Processing and Brazing
The company utilizes high-temperature conveyor and batch furnaces to perform glass-to-metal sealing and vacuum brazing. These processes are strictly controlled to manage the coefficients of thermal expansion (CTE) of the materials involved, preventing cracks or seal failures during the cooling phase.
Quality Assurance and Testing
Given the high-stakes nature of the industries ATG serves, their quality control measures are exhaustive.
* Helium Leak Testing: Every hermetic component is tested using mass spectrometer leak detectors to ensure leak rates meet or exceed 1x10^-8 atm cc/sec.
* Solderability Testing: Ensuring that the finished pins and packages can be easily integrated into the customerā??s PCB assembly process.
* Visual and Dimensional Inspection: Utilizing automated optical inspection (AOI) and coordinate measuring machines (CMM) to verify physical specifications.
Target Industries and Applications
The products manufactured by Advanced Technology Group Inc. are found in systems where failure is not an option.
- Aerospace and Defense: Used in flight control systems, radar modules, and missile guidance systems where components must survive rapid pressure changes and vibration.
- Medical Technology: Hermetic seals for implantable devices, such as pacemakers and neurostimulators, where protecting internal electronics from bodily fluids is vital.
- Oil and Gas: Downhole drilling tools and sensors that operate at high pressures and temperatures deep within the earth's crust.
- Telecommunications: Optical housings and laser diode packages for fiber-optic networks.
Through its commitment to engineering excellence and specialized manufacturing processes, Advanced Technology Group Inc. remains a cornerstone of the high-reliability electronics market, ensuring that the world's most sensitive semiconductor technologies can operate anywhere, from the bottom of the ocean to deep space.
