San Diego County’s largest fully integrated electronics manufacturing service companyHughes Circuits Inc, is celebrating 20 years of PCB service

Hughes Circuits is San Diego County’s largest fully integrated electronics manufacturing service (EMS) company.  We are the only EMS in San Diego which houses a complete PCB layout service bureau, complete PCB fabrication facility, full-service PCB assembly facility, and precision metal fabrication facility, all under one management team.  HCI currently employs more than 185 employees at its San Marcos facility of more than 42,000 sq feet.  Each year HCI invests hundreds of thousands of dollars in new capital equipment, training, and software to maintain our leading-edge technologies.

We can take your schematic and bill of materials and return fully populated assemblies in as little as 3-5 days.  Since all manufacturing operations are conducted on-site, there is no downtime for shipping.  Most importantly, our integrated manufacturing system reduces the number of prototype revisions since our multidisciplinary engineering teams understand the entire electronic manufacturing cycle.  We catch critical design issues before ever reaching the manufacturing floor.

We focus on the following market segments:

  • Time Critical manufacturing: new product introductions and quick turn production;
  • Leading Edge Technology,
  • High Reliability: Military, Medical, High Speed/RF, Advanced Materials,  Flex & Rigid-Flex, Highly Engineered, prototype and low volume commercial products.
  • We also offer value-added off-shore vendor management.
