Military and Aerospace PCBs

When it comes to printed circuit boards (PCBs), the military and aerospace industries have an ever-increasing demand for higher technical performance at affordable cost. Epec has made the investments in terms of both manufacturing equipment and manufacturing expertise that focuses on the high performance, reliability, and extreme environmental tolerances required for these industries.

requirements, including an expected lifetime of more than 5 years (sometimes extended to 15 years or longer). They are also required to perform in severe conditions which may include extremes of temperature, humidity, vibration, and impact, as well as survival in hostile environmental conditions such as salt spray, blowing sand or dust, and solar radiation.

Manufacturing for Critical Applications

Epec has over 65 years of experience in building circuit boards for these critical applications. We’ve sent PCBs on the Apollo 11 mission and we take pride that all circuit boards manufactured for military and aerospace applications require fixed and approved origins of manufacture with total traceability and security of Gerber data and engineering specifications. All our systems for quality and security have passed audits from the DOD, FDA, FAA, and most of the Tier 1 defense contractors.

Not only do we provide manufacturing expertise, but we also typically work very closely with our customers’ engineering teams on their designs. Because we understand that these products must operate in harsh environments, we utilize materials capable of withstanding extremes of stress, pressure, and temperature as part of our services.

America's Oldest. A History of Innovation.

Today at Epec, the customer comes first, and everything we do must be put through that filter. Whether it is developing e-commerce platforms to make it easier to work with us, or creating a NPI (new product introduction) process that helps our customers get to market faster, or the other 10 new projects we have in process, we must focus on building the new. By doing that every day, and by always making the customer our top priority, we plan on being here for another 65 years and then some.
