Frequently Asked Questions

What does Gorilla Circuits do?

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.

Why Gorilla Circuits?

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.

How long has Gorilla Circuits been in business?

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.

Where is Gorilla Circuits located?

Gorilla Circuits’ headquarters and manufacturing facilities are in San Jose, CA. We also have a sales office in Nashua, NH.

Where did the name Gorilla Circuits come from?

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.

Is Gorilla Circuits registered to ISO 9001?

Yes, our PCB fabrication and assembly are ISO 9001:2015 certified.

Does Gorilla Circuits have any other certifications?

MIL-PRF-55110, MIL-PRF31032, ITAR Registered. We are working on AS9100, NADCAP, ISO 13485.

What happens if I have a problem?

Every Gorilla Circuits customer has an assigned Project Manager and Account Manager. If you experience any issues with your order, please reach out to your Account Manager.
