Copper Core PCB

Copper core PCB is a copper substrate + Insulated layer + copper

circuits layer PCB,also, it is called copper substrate pcb, copper

based pcb,copper clad pcb.

As a MCPCB manufacturer,oneseine made various Copper core PCB for customers,

Which used for High Power LED lighter ( 1000W+ ) and power supply.

In LED field,there are 4 types of Copper based Circuit Board.

1. General Copper substrate Board.

2. COB Copper PCB(Chip on Board copper PCB)

LED chip Direct thermal sink to copper substrate.

3. Direct thermal path,no dielectric layer under the thermal path pad.

4.Direct thermal path,no dielectric layer,Aluminum-copper pcb.

Generally speaking, aluminum is the most economic option considering thermal conductivity, rigidness, and cost. Therefore, the base/core material of normal Metal Core PCB are made of aluminum. In Oneseine, if not special request, or notes, the metal core refer will be aluminum, then MCPCB will means Aluminum Core PCB. If you need Copper Core PCB, Steel Core PCB, or Stainless steel core PCB, you should add special notes in drawing.

Sometimes people will use abbreviation “MCPCB”, instead of the full name as Metal Core PCB, or Metal Core Printed Circuit Board. And also used different word refers the core/base, so you will also see different name of Metal Core PCB, such as Metal PCB, Metal Base PCB, Metal Backed PCB, Metal Clad PCB and Metal Core Board and so on.

MCPCBs are used instead of traditional FR4 or CEM3 PCBs because of the ability to efficiently dissipate heat away from the components. This is achieved by using a Thermally Conductive Dielectric Layer.

According to different location of metal core and trace layers of PCB, right now, we divide into five basic types:

Single Layer MCPCB(only one trace layer one one side);

COB MCPCB (chip-on-board MCPCB, one trace layers);

Double Layers MCPCB (two trace layers on the same side;

Double Sided MCPCB (two trace layers on each side);

Multi Layers MCPCB (More than 2 trace layers per board);
