                                             The role of metal core PCB in the Led industry

In today's technological age, the demand for lamps and lighting systems is on the rise. In addition, there are many LED products that are becoming more and more common in the lighting industry. In the past ten years, metal core printed circuit boards have become an integral part of the LED industry. This is no coincidence, as MCPCBs are a unique combination of metal plates, insulating layers, and additional copper foil. In addition, MCPCBs offer a wide range of advantages, including strong magnetic permeability and excellent heat dissipation. However, it is also important to analyze MCPCB boards through the prism of the LED industry. Therefore, in this article, we will take a closer look at the role and use of MCPCB fabrication in the LED industry. —Xiaobei design focus——PCB outsourcing drawing board design. Ten years to raise a person.

Why does the led industry use MCPCB

Custom MCPBCs are ideal for the LED industry for several reasons. First and foremost, the PCB specification includes the ability to integrate dielectric polymer layers. Furthermore, this provides significantly higher thermal conductivity. The domino effect is lower thermal resistance. In addition, LED metal core PCBs heat up at least 8 times faster than FR4 PCBs. In addition, the metal core printed circuit board can play the role of galvanization in the LED industry, because it can be laminated to dissipate heat. This can actually result in a significant reduction in the temperature of the heat-generating components. This feature can yield optimization results, as preservation of LED products and equipment is critical to preventing safety hazards. Furthermore, the prospect of efficient and rapid cooling is crucial to ensure constant light output.5 Types of PCB Surface finishing

Therefore, the end result is an extended lifetime and performance of LED products.

Metal Core PCB Heat Dissipation

Aluminum PCB has good thermal conductivity. At the same time, MCPCB prototypes (metal core PCB prototypes) have excellent processability and electrical insulation. However, increased demand for LED products has also led to heightened concerns about the outlook for thermal dissipation. Additionally, heat dissipation can degrade the overall performance of the device. Especially those that require high power to run.

This is why proper installation of the MCPCB structure is a key factor in solving this problem.

Many LEDs tend to consume between 2 and 5W. And often fail due to not removing the heat properly. More specifically, LED output is significantly reduced, while heat levels in LED products remain high. This is where the metal core PCB enters the frame. Then, the MCPCB specification can effectively neutralize the heat of all LEDs. This process occurs when the aluminum PCB base and dielectric layer connect the heat sink and IC. Additionally, a radiator is mounted on the main aluminum base. Therefore, this eliminates the need to add an additional number of heat sinks on top of surface added components. Best of all, it's an inexpensive and simple cooling solution.

Design rules for MCPCB LED board

As we said, MCPCB is an integral part of LED technology. Also, the design reason behind this is that the metal core PCB also reduces the number of LEDs needed to generate the lighting. Therefore, MCPCBs are ideal for street lighting, automotive LED applications, and backlight unit applications, among others.

However, it is important for every MCPCB manufacturer (metal core PCB manufacturer) to know certain MCPCB specifications and design rules. At this point, it must be emphasized that MCPCB design rules are similar to conventional PCBs. However, there are various widely used standardized MCPCB design models. Also, most of these MCPCB construction blueprints are based on specific design considerations. The first is to have an extra tooling border around the MCPCB board. Also, this represents a common design pattern per MCPCB specification.

Also, it is recommended to add additional tool holes. The most common designs incorporate 3mm. Besides, tool boundary and tool hole are one of the key elements of MCPCB led design. Combining these two components, the third element is the integration of fiducials into the MCPCB.

MCPCB Specifications in LED Technology

There are a few different MCPCBs in LED technology. Also, construction may vary by manufacturer. So it's safe to say that different versions exist. And most of these models can be modified differently. Also, some MCPCB suppliers tend to modify and adapt structures to suit specific configurations. However, there are some general norms that every professional developer needs to follow. The general specification for metal core PCB/aluminum PCB includes these general parts.

More specifically, the number of layers should be 1-2 layers. Also, it should be combined with a plate thickness of, max 3.0mm. As for the thermal conductivity, the general specification is 1.0-4W/mK. Additionally, the specification schematic includes copper thicknesses from 1 to 3 oz.

Additionally, there are other factors to consider:

1: Breakdown voltage: 2-8KV

2: Surface treatment: HAL (lead-free), immersion gold/tin, OSP, gold plating

The LED lighting industry has adopted single-sided or double-sided PCBs.
