Heavy Copper

Heavy copper Printed Circuit Board (PCBs) are essential in applications requiring high current carrying capacity, enhanced thermal management, and long-term reliability under demanding conditions. Achieving these benefits starts with careful material selection and process control to ensure the heavy copper PCB performs as intended across electrical, mechanical, and thermal requirements.

PICA Manufacturing Solutions provides heavy copper PCBs with copper thicknesses up to 12 ounces in volume production, delivering robust conductors capable of handling extreme power levels and heat dissipation. Our capabilities include selective copper plating and pattern plating to achieve the desired thick copper distribution exactly where it’s needed—balancing performance with cost efficiency.

When engineering thick copper PCBs, we evaluate critical parameters including high-Tg laminates, CTE matching, lamination processes, via-hole drilling and plating, substrate and copper foil characteristics, and solder mask compatibility. Our strict process control and quality assurance ensure that every heavy copper circuit board meets both functional and manufacturing standards.

By working closely with your engineering team, PICA can recommend the most manufacturable designs to achieve your required heavy copper thickness, while ensuring proper conductor width, layer stack-up, and plating uniformity. This collaborative approach ensures reliable performance in applications such as power electronics, automotive systems, industrial control, and any design where thick copper PCBs are critical for durability and efficiency.
