about ei microcircuits

leading the way at ei microcircuits

EI Microcircuits was incorporated in 1984. Our goal was to address a little-known technology that was to be the foundation for today’s miniaturization of electronics, known as surface mount technology, or SMT.


As an early adopter of SMT, few rules or production know-how were available at the time. We became an early pioneer in SMT pad and stencil design and one of the first EMS contractors to own and utilize robotic SMT placement machines.


Having now expanded to 3 manufacturing facilities with automated placement lines, solder robots and conformal coating lines, EI Microcircuits excels as a high mix, low-to-mid volume, technology driven EMS supplier. In addition, EI Microcircuits also offers value added services such as box-build, potting, warehousing & logistics, testing and much more.


After more than 30 years as a privately-owned family business, we continue to invest in state-of-the-art equipment, technologies, and people to maintain our place as a leader in contract manufacturing.

We believe…


Our employees are the heart of our business, and our customers are why we are in business. Therefore, at EI Microcircuits, creating the shortest connection between the two establishes a successful, efficient, long-lasting partnership unequaled in the EMS industry.

That a quality product is the direct result of knowing our customers’ needs. The interaction between the customer and the employee who is responsible for its manufacture is the means to do this.

In acting professionally, understanding the facts, and striving for excellence are key hallmarks of our daily business life.

hear it from our customers

"A delightful company to work with. Could not have done it without your expertise."

"EI excels in responsiveness, support and flexibility. I very much appreciate EI’s ability to adapt on the fly."

"I appreciate the work EI does most of all because it makes my job easier."

"Overall, EI does a great job in dealing with everything we throw at them. They are responsive and understanding of us, even though it may not always be the most reasonable of requests. As a buyer, I feel lucky to have a supplier that works with us like they do."

"Working on a project that had a board that was simply not manufacturable the way it was set up, EI went above and beyond to help with engineering and still met a very short deadline."
