We offer turnkey manufacturing: PCB Design, Fabrication, Assembly & Test of Rigid Printed Circuit Boards at our facilities in Silicon Valley. All services are controlled by our highly experienced Gorilla Circuits staff. Gorilla can seamlessly take your prototypes to mass production with our high volume fab partners.
Gorilla’s quality and capabilities are what stands us apart. We are still a small company when it comes to service and we stand by everything we manufacture.
Gorilla’s success and growth are a direct result of our turn-key PCB fab and assembly capabilities and quality. Our personalized service and flexibility is what truly differentiates us from other manufacturers. We employ some of the top Process Engineers in Silicon Valley and we have the best equipment on the market today.
Gorilla Circuits was formed in 2002. For over 17 years, the company has achieved phenomenal growth and is well-known for its high reliability, customer service, and quality of product.
With divisions in San Jose, CA and the greater Boston area, Gorilla Circuits is a leading US turnkey PCB manufacturing offering in house PCB Design, Fabrication, Assembly & Test. We serve Silicon Valley’s largest OEMs and specialize in the high-reliability, military/aerospace/defense, medical, and high technology marketplace.
Gorilla Circuits’ headquarters and manufacturing facilities are in San Jose, CA. We also have a sales office in Nashua, NH.
Gorilla Circuits was born during the tech boom crash of the early 00s when the thriving American tech manufacturing market had become a cutthroat industry. Many struggled to compete with overseas competition. A joking reference that Silicon Valley had become like guerilla warfare was made at a dinner with the founding members. Trying to set our company apart from the rest, guerilla turned into Gorilla and the offbeat moniker stuck. Gorilla continues to set itself apart with its dedication to product quality and service.

Gorilla Circuits performs 100% AOI on all cores (signals and planes). We test all boards 100% against the netlist using Flying Probe. We also have a state of the art lab for cross-sectioning and IST Testing.
Gorilla Circuits state of the art Assembly facility offers Advanced Screen Printing, Self Sufficient Liquid Nitrogen Generators, Flying Probe Tests, and Parametric Bench Tests. We offer quick turn NPI with a dedicated team, SMT and PTH lines as well as a Process Control Plan implemented through the entire process flow. Our experienced Front end engineers service DFM reviews. We have Pick and Place with Inline SPI (solder paste inspection), AOI (Automatic Optical Inspection) for SMT operation. BGA/hidden solder joint inspection with real time 3D X-ray and solder joint failure, first article inspection with 2D/3D X-ray.
We have a full Chemical Analysis Lab that is DoD Qualified. We perform IST Testing and cross-sectioning.
