Competitive Small to Medium Batch PCB Fab & PCBA Supplier

Heavy Copper PCB

heavy copper pcb

Heavy Copper PCBs are commonly used for power supply systems or electronic devices. They are made with a finished copper weight that is greater than four ounces. Our standard copper PCBs weigh between one and two ounces, and the thickness of heavy copper is able to conduct higher currents and provide thermal distribution. In addition, your design can include complex switches in smaller spaces with this material.

Our Experience

At MKTPCB, we have over 10 years of experience manufacturing and assembling high-quality Heavy Copper PCBs as well as many other PCB products. Our highly qualified engineers run tests for manufacturing on every single circuit file to ensure that all questions and concerns are addressed prior to production.

In addition, we have an in-house quality control department that allows us to guarantee that our PCBs are the highest quality. We are proud to offer reliable and fast turnaround times on our PCB fabrication, and we work with top businesses to produce high-quality PCBs for all devices. We have the experience and the knowledge to fabricate top of the line Heavy Copper PCBs for devices with high currents, and we have a 99% rating for customer satisfaction.

When to Use Heavy Copper PCB Service

You need to use Heavy Copper PCB service when you require higher currents and better thermal distribution. Heavy Copper PCBs have better thermal management to allow for heat dissipation, and they keep your inner components cool for increased reliability and functionality. They allow for an increase in the current carrying capacity, which is necessary for certain applications, including weapons control systems, welding equipment manufacturing, HVAC systems, power supplies for radar systems, high power planar transformers, battery charger systems, and more.

Features of Heavy Copper PCB Service

Heavy Copper PCBs have a finished copper weight of four ounces or more. This added thickness makes it possible for them to conduct higher currents while dissipating heat and keeping the component cool during operation. In addition, the mechanical strength is greater at the connector sites, and we are able to incorporate many weights on the same layer of circuitry, which allows the end product size to be smaller. You can use specialized materials in your design with little risk of failure.

MKTPCB offers the following capabilities in the fabrication of Heavy Copper PCBs:

  • Standard IPC2 quality
  • Two to 24 Layers
  • Quantities of one to 10,000 pieces
  • Build times of two days to five weeks

In addition, our Heavy Copper PCBs are fabricated using varying board sizes, thicknesses, and weights to ensure that the PCB is ideal for use in your specific devices.
