At Northwest Circuits Corp…

We are large enough to offer the financial strength, processes and capabilities of large CM's yet small enough to provide a unique personalized service experience for each customer.  Privately owned and established in 1991, we are able to react quickly to market and customer needs. No bureaucracy here, just quick and focused results. We are considered an essential business both in US and Mexico.

NWC has extensive experience in PCB Prototyping and Quick-turn Production Services. We understand that this is a critical part in the New Product Introduction and Manufacturing processes. ​
