Heavy copper PCB, also named thick-copper PCB, refers to a kind of circuit board that has a copper thickness of more than 2 oz, normally the range of its copper thickness is from 3oz to 14oz. The higher the copper thickness is, the higher the current the PCB can handle. This type of circuit board is manufactured by using special etching and plating methods such as differential etching and step plating. It can handle high current and high power circuits thanks to its great conductivity.

MOKO has obtained many certifications including ISO9001:2015, ROHS, BSCI, IPC, and UL, which demonstrates our commitment to stringent PCB quality control.
Heavy copper PCBs provide better heat sink capability, enhanced mechanical properties, and greater ability to handle higher current.
High copper circuit boards are applicable in many areas such as power supplies electronics, automotive electronics, solar power systems, and industrial equipment.
Heavy copper printed circuit boards typically feature copper thicknesses ranging from 3 oz/ft² to 20 oz/ft².
Standard PCBs feature 1 oz/ft² copper while heavy copper PCBs employ much thicker copper layers in order to deliver increased power capacity.
The disadvantages of heavy copper PCB include: higher manufacturing costs, long etching times during the fabrication, and more difficult to realize fine pitch design.
The etching process in heavy copper PCB manufacturing takes longer time than standard PCB due to the thick copper. Additionally, photoresist exposure settings have to be changed and plating procedures need to be well controlled in order to get the right thickness of copper.
Yes, heavy copper PCBs are designed to handle high temperature because they offer good thermal conductivity through the copper layers.
MOKO Technology has the full capability to support heavy copper PCB services in design, prototype, manufacturing, assembly, and testing.
Heavy copper PCBs cost more than standard PCBs due to the additional amount of copper and the more difficult production process.
MOKO Technology can manufacture heavy copper PCBs with copper thicknesses up to 14 oz.
