What Our Clients Have to Say
“With all of the support we receive from ETI, we will continue to deliver quality product on time that our customers have come to expect.”
– Vesna, Supplier Performance Lead | Collins Aerospace

WHAT WE DO
Your complex requirements call for a trusted supply chain partner with sophisticated, integrated capabilities. Rigorous, reliable and responsive, we deliver quality and value in aerospace PCB assembly and cable harness and wire assembly through continuous improvement, personalized service and ISO 9001:2015 quality management.
ETI/ACH has served as a source of high-quality PCB assembly and custom wire and cable products for over 30 years. We can provide extremely complex small batches or large production runs. Throughout our years in business, we’ve provided customers from virtually every industry—including aerospace—with electrical connection solutions for some of their most challenging applications.

In aerospace systems, performance, reliability, and traceability are non-negotiable. Whether you’re developing mission-critical avionics, flight control electronics, or rugged communication modules, early design optimization is essential for efficient production and long-term performance. As an experienced aerospace PCB manufacturer and partner among aerospace wire harness manufacturers, we collaborate with engineering teams to refine your designs for manufacturability and certification readiness.
Our DFM support for aerospace electronics includes:
By integrating manufacturability insights early, we help reduce production issues, improve assembly consistency, and deliver aerospace electronics that meet demanding industry standards.
CAPABILITIES
Proven capabilities make us a trusted partner for customers in many industries.

Expertise in materials, tooling and processes delivers high-quality wire harnesses.

Robust cable assemblies for the most challenging and technical applications.


We build PCB assemblies for cabin lighting, controls and other applications in high-end corporate jets, whether new or retrofit. Collins Aerospace, part of the Raytheon Technologies family, is one such customer. On the ground, for our customer BAPI and their customer, the Jet Propulsion Laboratory, a division of NASA, we provide printed circuit board assemblies for immersion sensors that are incorporated into maintaining a 33-story-high antenna and the giant turntable on which it is mounted.
Traveling, navigation and communication in space wouldn’t be possible if not for the electronics containing PCB assemblies. Strict process controls are necessary for these assemblies, and ETI/ACH is disciplined in meeting complex requirements for these specialized components. Aerospace electronics contain robust and reliable printed circuit board assemblies required for systems such as:
“With all of the support we receive from ETI, we will continue to deliver quality product on time that our customers have come to expect.”
– Vesna, Supplier Performance Lead | Collins Aerospace
“First of all, we would like to thank you and the entire staff at ETI who were involved to make sure the first round of boards got completed and delivered on-time. We are very delighted to say the boards are now being tested and working well.”
–Dino, Engineering Manager | Food Equipment Products
“We have finished the review of the most recent shipment of box builds delivered. These chassis were very close to perfection. Please let everyone know at your facility we are very satisfied and appreciate all the time and effort spent getting to this point.”
– Brian, Quality Systems Manager | Specialized Power Supplies
“Thank you for all your hard work and great communication. I know we are in good hands with your organization.”
– Suzie, Buyer | Gaming Industry
“Thank you so much for your help and extremely quick service! You really got us out of a jam, and we appreciate your understanding.”
– Bill, Product Manager | Tube & Pipe Cutting Equipment
“Yesterday, I expressed to our management team how you folks have taken things to a different level. I know that isn’t easy, but when you hire ‘rock stars’ such as Margaret, Laine and Sarah and build on their expertise, it makes a huge difference to our company. Because of the strong support they provide it is so easy to view ACH/ETI as a true business partner and not just another vendor. I hope this partnership extends far beyond our transitions into retirement. That would be a great legacy.“
– Michael, Senior Buyer
“We really appreciate the cooperation and efforts from your team on this project.”
– Dianna, Supply Chain Manager
“Your team does a great job informing us on project updates. When something is needed they call us and then follow up with an email. Our relationships between both teams is growing stronger each day.”
– Mike, Supply Chain Supervisor
