In today's technological age, the demand for lights and lighting systems is on the rise. In addition, there are many LED products becoming more and more common in the lighting industry. In the past decade, 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 foils. In addition, MCPCBS have a wide range of advantages, including strong magnetic conductivity 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 manufacturing in the LED industry.
Why should the led industry use MCPCB
Custom MCPBC is ideal for the LED industry for several reasons. First and foremost, the PCB specification includes the ability to integrate dielectric polymer layers. In addition, 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, metal core printed circuit boards can play a galvanizing role in the LED industry, because it can be laminated to dissipate heat. This can actually reduce the temperature of the heating part significantly. This feature can have an optimization effect, as the retention of LED products and devices is essential to prevent safety hazards. In addition, the prospect of efficient and rapid cooling is essential to ensure a constant light output.
Therefore, the end result is to extend the service life and performance of LED products.
Metal core PCB cooling
Aluminum PCB has good thermal conductivity. At the same time, the MCPCB prototype (metal PCB prototype) has excellent machining performance and electrical insulation. However, the increased demand for LED products has also led to an increased level of concern about the prospect of heat dissipation. In addition, heat dissipation degrades the overall performance of the device. Especially those that require high power to operate.
This is why the proper installation of the MCPCB structure is a key factor in solving this problem.
Many leds tend to consume between 2 and 5W. And it often fails because the heat is not removed properly. More specifically, LED output decreased significantly, while the heat level of LED products remained high. This is where the metal core PCB enters the frame. The MCPCB specification can then effectively neutralize the heat of all leds. This process occurs when the aluminum PCB base connects the heat sink and IC with the dielectric layer. In addition, a heat sink is installed on the main aluminum base. Thus, this eliminates the possibility of needing to add an additional number of heat sinks on top of the elements added on the surface. Best of all, it is an inexpensive and simple cooling solution.
MCPCB LED board design rules
As we said, MCPCB is an integral part of LED technology. In addition, the design reason behind this is that metal core PCBS can also reduce the number of leds required to produce lighting. Therefore, MCPCBS are ideal for street lights, automotive LED applications and backlight unit applications.
However, it is important for every MCPCB manufacturer (metal PCB manufacturer) to know certain MCPCB specifications and design rules. In this regard, it must be emphasized that MCPCB design rules are similar to traditional PCBS. However, there are a variety of widely used standardized MCPCB design models. Moreover, most of these MCPCB blueprints are based on specific design considerations. The first is an additional tool border around the MCPCB board. In addition, this represents a common design pattern for each MCPCB specification.
In addition, it is recommended to add additional tool holes. The most common design integrates 3mm. In addition, tool boundaries and tool holes are one of the key elements of MCPCB led design. Combining these two components, the third element is the integration of the reference point into the MCPCB.
MCPCB specification in LED technology
There are several different MCPCBS in LED technology. In addition, construction may vary from manufacturer to manufacturer. Therefore, it is safe to say that different versions exist. And most of these models can be modified differently. In addition, some MCPCB vendors tend to modify and adjust the structure to fit a particular configuration. However, there are general specifications that every professional developer needs to follow. The common specification for metal core PCBS/aluminum PCBS includes these common sections.
More specifically, the number of layers should be 1-2. In addition, it should be combined with a board thickness of 05.mm, up to 3.0mm. As for thermal conductivity, the general specification is 1.0-4W/mK. In addition, the specification diagram includes copper thicknesses from 1 to 3oz.
In addition, there are other factors to consider:
1: Breakdown voltage: 2-8KV
2: Surface treatment: HAL (lead-free), gold/tin, OSP, gold plating
The LED lighting industry uses PCB single panel or dual panel.
All in all, the metal core printed circuit board is a major technological innovation. In addition, it is a complete specification of the LED manufacturing process. Moreover, this revolutionary innovation is one of the key components behind the outstanding performance of LED products. After all, the use of MCPCB led boards in these led products and applications can greatly reduce the overall heat generated. Therefore, it is safe to say that MCPCB is one of the innovations for the future.
