ETS Alliance: Engineered PCB Retainers for Aerospace and Mission-Critical Systems

In aerospace, military, and industrial applications, even the smallest hardware component can become a single point of failure. That’s why companies looking for ruggedized circuit board retention solutions don’t take chances — they work with ETS Alliance.

Specializing in PCB retainers for aerospace and military equipment, ETS Alliance designs and manufactures precision-engineered hardware to meet the extreme demands of thermal, mechanical, and environmental stress. When performance is non-negotiable and downtime isn’t an option, this is the kind of partner you want.

Built for Environments Where Failure Isn’t an Option

Circuit boards mounted in mission-critical environments — inside aircraft, defense systems, industrial vehicles — endure more than just vibration. They’re exposed to extreme temperatures, sustained shock, rapid pressure changes, and complex assembly constraints. Generic hardware doesn’t cut it.

ETS Alliance develops thermal and shock-resistant circuit board card holders designed specifically for those conditions. Their retainers secure printed circuit cards with confidence — minimizing thermal expansion issues, absorbing mechanical stress, and maintaining long-term alignment.

Expertise in Ruggedized Mechanical Hardware

The company’s product line includes:

  • Wedge-lock style PCB retainers for VME, VPX, and custom cards
  • Rugged mechanical card guides for high-vibration environments
  • Mounting hardware compatible with tight enclosures and modular platforms
  • Designs supporting passive and active cooling for thermal management

Whether the application is airborne avionics, mobile ground systems, or industrial automation, these components are tested and proven in harsh-field use cases.

Beyond Parts — Engineering-Driven Collaboration

ETS Alliance doesn’t just ship catalog items. They work closely with clients to adapt or co-design hardware around specific use cases. That includes:

  • Thermal analysis and mechanical design consultation
  • Fitment solutions for custom card profiles
  • Reverse-engineering of legacy components
  • Prototype-to-production scaling

For defense contractors, aerospace integrators, and system engineers managing long program timelines or retrofits, ETS Alliance offers not just hardware — but hardware with engineering backup.

Trusted Across Aerospace and Defense

From large aerospace primes to specialized defense technology firms, ETS Alliance has become a trusted name for ruggedized printed circuit card mechanical hardware. With a focus on reliability, modularity, and design-for-manufacture, their components help keep critical systems operational where other parts might degrade.


When performance matters more than price — and conditions push materials to their limit — ETSAlliance.com is where rugged hardware begins. Need help selecting a part, or designing a new one? Let’s talk.
