What is Copper Based PCB
Copper based PCB is a type of metal based PCB, it is PCBs made by copper substrate. As the leader of the thermal conductivity in the metal substrate MCPCB(metal core PCB), the copper PCB has a thermal conductivity of up to 400 watts. It can meet the needs of higher power LED light sources after the aluminum substrate, and solve the various heat problems such as high power dead light, serious light decay, and high heat generation.
As the more active star products in the metal substrate, copper based PCBs and the aluminum substrate PCBs have their advantages and are widely used, which are common in cars, stage lights, control panels, photographic lights, and projection lights, Stage laser lamp and other products are excellent high-power accessories.

Copper Based PCB and Features
Copper Based PCB and Production Process
Sleeve card position
The sleeve frame should be widened so that there is a distance of more than 1mm between it and the copper base to prevent the extended part of the high-temperature tape from affecting the unit or causing air bubbles during pressing.
After lamination, it enters the multilayer board processing process, but some through holes pass through the inner copper base, and unique copper metal drills must be used for this part of the holes. At the same time, the speed of drilling these holes should be at most 25,000 rpm. In addition, the speed should not exceed 0.5m/min.
Design of large holes for gongs: special copper substrate gong cutters must be used for the heat dissipation holes of gongs. At the same time, the rotation speed of these holes should not exceed 15,000 rpm, and the stroke speed should not exceed 3m/min.
Surface copper thickness control
Open the cover
Peel off the outer layer of the bending position through high-temperature adhesive bonding so that the copper base at the bending position is exposed. At the same time, if there are screw holes, they are also exposed during this process.
Surface treatment such as HASL, OSP, ENIG etc.

Copper’s susceptibility to oxidation can result in copper corrosion over time and lead to degraded performance.
Copper pcbs are prone to overheating and short-circuiting.
Copper base pcbs are less durable than other PCBs, thanks to copper’s relatively weak physical properties.
Copper base PCBs are much more expensive than normal FR4 circuit boards.
Yes, there are several possible sustitutes for copper-based PCBs. These alternatives involve aluminum, glass-epoxy, flex circuits, and polymer thick film board materials. But we always need to consult the copper base PCBs designer or the copper base PCBs manufacturer before changing the base material.
It depends, high thermal conductivity is the most important characteristic of copper based PCB, if your electronic devices need extremely high head dissipation requirement, then copper backed PCB could be a good choice.
No, they are the same thing. They are printed circuit boards with thick copper plate attached to meet special functions.
Please keep the following precautions in mind when handling copper-based PCBs.
It is essential always to use insulated tools when handling copper base pcbs.
Remember to wear safety glasses and a dust mask while handling these boards.
Copper pcb should be kept away from moisture areas.
Although most of the copper foil based PCBs are one layers, but some more complex electronic device all need multilayer metal more PCB. Very experienced production and quality team are a must for a multilayer metal more PCB manufacturer.
