Company Information

Millennium Circuits Limited (MCL) is an industry-leading, printed circuit board supplier based in Pennsylvania. Our goal is simple: we want to give you the best PCB each and every time — engineered, produced, and competitively priced.

Whether we’re delivering small batches or medium- to high-volume PCBs or generating a brand-new prototype for your brand-new product, we’ve got one goal in mind: Redefining Customer Service. That’s our motto and our commitment to you, delivering the best service you’ll experience so that we become your go-to PCB supplier.

MCL began its life with a dream in a large basement that quickly became far too small. We’ve since expanded our operations to now reach more than 400 customers all over the globe. While our corporate office is in central Pennsylvania, manufacturing locations are located both domestic and offshore.

Our Roots

Our capabilities allow us to create your PCBs here in the United States or to offer offshore manufacturing to help you put more of your budget toward engineering and materials. No matter where your product is made, we deliver the same quality and commitment. We are the leading printed circuit board supplier in PA.

Large-volume PCB fabrication services are available to all of our clients, no matter where you operate, what industry you serve or how you want your boards developed.

A Brief History

The early goal here at MCL was to become a leading printed circuit board supplier. Founded in 2005, we serve as the only privately owned, ISO-9001 certified PCB board fabrication company in central PA.

In 2012, 2013, and 2014, MCL was honored to be one of the “Top 50 Fastest Growing Companies in Central PA.”  That was a great motivation to help us ramp up to supply high-volume PCBs.

In 2015, MCL was ranked among the Top 250 companies in Pennsylvania. We felt it was the perfect way to celebrate our company, our people and our customers.

Since then, we’ve opened three more manufacturing locations and, in 2016, we moved into our modern, newly built facility in the heart of central Pennsylvania.  In 2016, MCL was listed on the Inc. 5000 list of the fastest-growing private companies in America.
