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 based PCBs are much more complex than standard FR4 PCB production processes, such as outline profiling/cutting;
Copper base PCBs are much more expensive than regular FR4 circuit boards;
Normally, only one or two signal layers on copper-based PCBs, it is not suitable for multilayer PCBs.
Yes, there are several possible substitutes for copper-based PCBs. These alternatives involve aluminum, alloy compound, reinforced FR4 and other high-tech PCB 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.
Yes. Metal core PCBs are the circuit board produced with metal, such as aluminium, copper, iron and other alloy. But copper based PCB means the PCBs are produced with copper substrate. Copper-based PCB is one kind of metal core PCB.
The first step in copper-based PCB design is determining the material type that should be used according to your applications.
Please keep the following precautions in mind when handling copper-based PCBs.
Always following ISO9001 rules in production processes
Use insulated tools when handling copper base PCBs.
Remember to store Copper PCB in a temperature and humidity controlled environment.
Storing copper core PCBs in an environment with low relative humidity (RH) and a specific temperature range is essential to protect them from oxidation. Additionally, copper metal core PCBs should be stored in static-free packaging or containers made of non-conductive materials.
There is no difference between these two terms. All of them are circuit boards with a copper plate attached to meet the high heat dissipation requirement of high power electronic boards.
Although most of the copper foil-based PCBs are one layers, but some more complex electronic devices all need multilayer metal core PCB. A multilayer metal core PCB manufacturer must have a very experienced production and quality team.
