MCPCB

what is mcpcb?

A MCPCB is a form of PCB in which the foundation material for the heat-spreader area of the board is metal. The copper foil used in MCPCBs has exceptional magnetic conductivity, great heat dissipation, high mechanical strength, and favorable processing features. It is composed of a thermal insulating layer, also known as the IMS layer, a metal plate, and a copper sheet. The core of an MCPCB serves to divert heat away from key PCB components and into less important locations, such as the metallic core or the metal heatsink backing. Aluminum, copper, or a combination of unique metal alloys are frequently used as the basic materials in metal core PCBs.

Feature of MCPCB

A metal core printed circuit board (MCPCB) is designed to dissipate heat. This eliminates the risk of the components getting hot, and it ensures that the device operates at its optimal performance. It also prolongs the lifespan of the components by improving their performance.

Compared to a metal core printed circuit board, a standard FR4 PCB is significantly less efficient when it comes to transferring heat. This is because the high heat generated by certain applications can lead to issues with cooling. A metal core board is ideal for these situations.

Why we need MCPCB?

A technique known as Metal Core PCB, MCPCB, or occasionally Thermal PCB was created to get around the thermal restrictions of the FR-4 material. If your PCB boards must operate in a high temperature environment, copper is a better option than FR4 for the metal core. Aluminum (or Aluminium) is another option. For electric isolation, there is a dielectric layer positioned between the metal core and the copper foil. High thermal conductivity is one of the unique characteristics of the particular dielectric. Consequently, the term Insulated Metal Substrate also applies to metal core PCB substrate (IMS). Metal Core PCBs, also known as IMS PCBs, are renowned for their capacity to effectively offer heat dissipation for electronic goods.

Although Copper Core PCB performs better than Aluminum Core PCB, Copper Core PCB is comparatively more costly. When you are aware of the increasing price of copper, you can visualize it. Because aluminum PCBs are substantially less expensive, customers request them more frequently.

Benefits of MCPCB

When a project calls for significant heat dissipation, insulated metal substrate technology offers a long list of benefits. The majority of engineers and designers use metal core PCB boards to benefit from their benefits over FR4 PCBs:

1. Keep the PCB part temperature normal and extend PCB part work life
2. Heat Transfer efficiency nearly 10 times faster than the normal material FR4 in PCB
3. lower thermal resistance high thermal conductivity

Why MCPCB popular in LED Manufacturing?

The good thermal conductivity of aluminum can be attributed to its properties. The MCPCB prototype, on the other hand, provides exceptional electrical insulation and processing properties. Unfortunately, excessive heat can affect the performance of electronic devices, such as those that require high power. Due to the increasing number of LED products, the concern about the possibility of heat dissipation has increased.

Due to the various advantages of custom molded polycarbonate PCBs (PCPCBs), it is considered an ideal material for LED industry. One of these is its ability to integrate a dielectric polymer layer. This allows for higher thermal conductivity and a lower thermal resistance.

Compared to the FR4 PCBs, the metal core LED PCB can generate heat up to 8 times faster. It also has a unique ability to cool the components by absorbing heat. This material can act as a conductor and can reduce the overall heat generation.

This feature can help improve the life and performance of LED products by preventing them from getting damaged or posing a safety hazard. Another important factor that can be considered is the fast cooling of the device to ensure that the output of the light is constant.

Application of MCPCB

Due to the various applications that require a metal core printed circuit board, such as those related to solid state lighting, it is important that it is designed to provide a high-speed and reliable cooling solution. One of the most important factors that a metal core printed circuit board should consider is the dissipation of heat. In the case of LED’s, the heat generated by these devices can negatively affect their operation.

There are a wide variety of applications for metal core printed circuit boards, such as those related to LED’s. These include automotive lighting, industrial monitoring systems, and medical devices.

What does Mcpcb stand for?

Mcpcb stand for metal core PCB. It is type of PCB core are made of metals, such as copper, aluminun, alloy etc.

How do I manufacture Mcpcb?

Below there is MCPCB manfacturing process:

1. Cutting of laminate: Cut a single-sided MCPCB laminate to the appropriate panel size.
2. Drill bigger holes (often 1 mm larger) in the same PTH locations as necessary.
3. To isolate the electrical connection between the outer layers and the metal core, completely cover the drilled holes with glue.
4. Laminate Pre-treatment: Abrading the metal core’s rear side until it is sufficiently rough to allow for the bonding of copper foil and PP.
5. Lamination: To create a double-sided MCPCB laminate, press and laminate copper foil (one sheet), PP (dielectric layer), and the single-sided CCL created in the previous phase together.
6. Drill holes in the same areas as the first drilling but on cured resin. These holes will subsequently produce PTHs.

If you have ability you can make MCPCB by yourself, if you don’t have fabricating MCPCB facilities, you can sourcing a reliable PCB manufacturer work for you.
