PCB Fabrication

Trusted PCB manufacturing experts since 1980

Since 1980, PCB fabrication has been one of our core competencies. We’ve developed countless advanced techniques and processes that have saved our customers both time and money.
We are the circuit experts. While other companies were just taking their first steps, Cirexx was learning to fly. We have the industry leading procedures, facilities, and team to fulfill all of your PCB fabrication needs. Our expertise allows us to excel where other fail. Have a complex rigid board with blind, buried, or stacked vias? No problem. What about a high layer count flexible circuit that needs bookbinding? Easy. We have the technology and the team in-house to fabricate your most complex PCBs.

Made in the U.S.A., all PCB manufacturing is done here in Santa Clara, California. Our product offerings listed below, are industry leading. Cirexx manufactures a wide variety of PCB’s, from single layer FR4 rigid circuit boards, to high layer-count flex and rigid-flex circuit boards, using exotic materials.
