About Millennium Circuits Limited
Millennium Circuits Limited (MCL) is a printed circuit board supplier headquartered in Harrisburg, Pennsylvania. Founded in 2005, the company has focused exclusively on bare PCB procurement, positioning itself as a value-added partner for customers ranging from prototype to production volumes. MCL supplies bare PCBs across a wide range of technologies: rigid, flex, rigid-flex, aluminum, ceramic, heavy copper, RF/microwave, and HDI constructions. Its manufacturing network—both domestic and offshore—supports 1 to 44 layers, a 35:1 drill aspect ratio, maximum panel sizes of 24 by 51 inches, blind and buried vias, micro vias, via-in-pad with conductive or non-conductive fill, controlled impedance, and high copper thicknesses. Surface finish options include ENIG, immersion silver, immersion tin, ENEPIG, HASL, lead-free HAL, OSP, hard gold, soft gold, and selective finishes. The company also provides engineering services such as design-for-manufacturability reviews, design rule checks, stack-up design, impedance modeling, panelization, and cost consulting, along with product life cycle management. MCL reports 1,106 customers served, a 97% on-time delivery rate, and 99.6% of PCBs shipped without defects, backed by over 100 years of combined PCB manufacturing expertise among its team. The company serves industries including medical, automotive, power and energy, industrial equipment, telecommunications, defense, consumer electronics, marine, test and measurement, and LED lighting. Its customer base comprises contract manufacturers, original equipment manufacturers, and design firms. MCL differentiates itself through a U.S.-based Customer Concierge team that provides same-day quotes and dedicated support from request through delivery. It maintains strategic, long-term partnerships with vetted manufacturing facilities—selected via a proprietary Vendor IQ evaluation—rather than sourcing from the lowest bidder. The company is ISO 9001 certified (since 2014) and complies with RoHS, REACH, ITAR, IPC-A-600, and IPC-6012 standards, emphasizing a 'right-fit' supplier approach to ensure quality and consistency.
