PCB Manufacturing Companies in California

California has approximately 35,000 manufacturing establishments and 1,300,000 manufacturing employees. California is the largest manufacturing state by output, leading in aerospace, semiconductors, medical devices, and food processing across its diverse regional economies.

California is one of the leading states for pcb manufacturing. PCB (printed circuit board) manufacturing encompasses companies that fabricate bare circuit boards and assemble populated boards with electronic components. The US PCB industry includes bare board fabricators, electronics manufacturing services (EMS) providers, and specialty high-reliability PCB producers serving defense, aerospace, medical, and industrial markets.

Bare Board Fabricators: Companies manufacturing multi-layer, HDI, flex, and rigid-flex printed circuit boards from raw laminate materials.

EMS Providers: Electronics manufacturing services companies like Jabil and Flex that assemble and test populated PCBs at scale.

High-Reliability PCB Makers: Specialty fabricators producing mil-spec, aerospace, and medical-grade circuit boards with enhanced quality systems.

Prototype & Quick-Turn Shops: Fast-turnaround PCB fabricators and assemblers serving engineering teams with prototype and low-volume production.

Flex Circuit Manufacturers: Companies specializing in flexible and rigid-flex circuit fabrication for compact, high-density applications.

Major industrial centers in California include Los Angeles, San Diego, San Jose, San Francisco, Fresno, Irvine, and Long Beach. These cities have concentrations of manufacturers across sectors including semiconductor manufacturing, aerospace manufacturing, and medical device manufacturing.
