About Us

Hughes Circuits Incorporated (HCI) is San Diego County’s largest fully integrated Electronic Manufacturing Service (EMS) providing Printed Circuit Board Design, Fabrication, and Assembly all in one facility under one management.  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 are a woman owned small business, ISO 9000 certified, MIL 55110 and MIL PRF 31032 approved, UL recognized.  We layout printed circuit boards (PCB’s) to IPC 2222, build to IPC 6012, IPC 6014, and IPC 6018, we assemble to JSTD 001 and IPC 610D.  All PCB layout engineers are IPC CID or CID+, all PCB inspectors are certified to IPC 600, and all PCB assembly personal are certified to JSTD 001 and IPC 610D.

We’d like to become your EMS provider of choice, by providing unmatched value in your electronic product development and manufacturing supply chain.

HCI has experienced rapid revenue growth of more than 35% year over year by keeping focus on the needs of the highly competitive electronics industry.  In May of 2009 we celebrated our 10th year of business.  We focus on cycle time reduction, lean manufacturing, quality, superior engineering support and customer service.


Unparalleled Expertise & Manufacturing Clarity


The electronics supply chain is highly fragmented requiring complex management of separate vendors which know little of the upstream and downstream processes.  This often results in miscommunications and time delays as complex product questions must be filtered through and between multiple unrelated vendors.  This is an imperfect process which yields many opportunities for delays and defects.  HCI is an expert in all stages of the product development cycle including pcb design, fabrication, component sourcing, and assembly.  No more delays or finger pointing between vendors when a problem arises!


Leading Edge Technology

Investments in training, research and the latest technology equipment provides HCI the ability to manufacture the most technologically demanding products.  There is no printed circuit board manufacturer or assembly facility that can beat our technical capabilities.
