Considerations for a Copper Core PCB Manufacturer

Have you witnessed the dynamic changes in the manufacture of printed circuit boards? The world has been continuously working on improving and miniaturizing electronic devices. Therefore, there has been an impeccable effort towards substituting older versions of PCBs with low thermal resistance with newer ones with better heat transfer efficiency. Equally important is that the difference between one metal core PCB and the other lies in their heat transfer properties, power density, manufacturing material, etc. For instance, a printed circuit board with a good heat spreader portion will have a high thermal conductivity.

On the other hand, the absence of a direct thermal path will result in a metal core PCB with low thermal conductivity. Such a circuit board can only work under low-temperature variations. Moreover, we refer to a printed circuit board with a copper substrate as a copper substrate PCB while that one with an aluminum substrate is known as an aluminum PCB. Copper core PCBs are printed circuit boards with a coper core that provides a better heat dissipation than other traditional forms of metal core PCBs. The following are the top 5 copper core PCB manufacturers in the world.

Japanese multinational firm Hitachi, Ltd. has its headquarters in Chiyoda, Tokyo. The organization, which also houses the Hitachi brand, is the parent of the Hitachi Group. In addition, Hitachi Copper Core PCB Manufacturers, One of the world’s biggest and most reputable printed circuit board producers, has been operating for more than 20 years. Additionally, they have a lengthy history of offering their clients high-quality goods and services.


Hitachi Copper Core PCBs are useful in various electronic items, including computers, cell phones, and digital cameras. Hitachi manufactures its Copper Core PCBs using a unique method that begins with depositing a thin layer of copper onto a substrate. A photo-imageable dielectric substance then follows on top of the copper. The exposure of the dielectric polymer layer to U.V. light leads it to become brittle. The tempered dielectric is then employed as a mask to remove the exposed copper.

Consequently, there is a few microns thick copper coating. The remaining copper layer is highly conductive and has good electrical qualities—Copper Core PCBs from Hitachi feature superior signal integrity and crosstalk resistance. In addition, they can process high-speed communications with minimum signal loss. The circuit boards have proper thermal management as they have a stable thermal path pad. Consequently, the critical board components are at a reduced risk of thermal destruction. Copper Core PCBs from Hitachi are available in various sizes and forms to accommodate any application.


Lead-free and RoHS-compliant, Hitachi Copper Core PCBs are devoid of lead. In addition, they are UL-approved and meet all IPC-A-610 specifications. Furthermore, the company holds the ISO-9001:2008 quality management system.


As the globe advances, it becomes increasingly important to have a reliable and high-quality printed circuit board (PCB). A PCB is a platform that enables the interconnection and cooperation of electrical components. They are present in most modern devices, including cell phones and laptops. The copper core PCBs consists of a thin copper layer coated with a solder mask onto a dielectric substrate. Copper provides higher electrical and thermal conductivity and superior durability and dependability. Therefore, copper core PCBs are commonly applicable in high-end electrical equipment. Copper core PCB manufacturers are plenty, but are not all equal.
