Understanding metal core pcbs beginner’s concepts
mcpcb manufacturing Thermal conductivity
Aluminum PCBs also called metal core PCBs. They are the most used in mcpcb manufacturing LED lighting projects. Why do lamps like to use aluminum PCB? The reason is that the thermal conductivity of the metal core material is good. We know that the temperature is very high when the lamp is working, so it is very important to find a good heat dissipation material to help it.
Understanding Metal core pcbs
mcpcb manufacturing is a general term for all printed circuit boards with a metal alloy for heat dissipation and heat conduction.
The most common materials are two types:
- one is aluminum with high thermal conductivity and heat dissipation performance but relatively low cost
- and the other is copper with excellent thermal conductivity and heat dissipation characteristics but relatively high cost.
Comparison of heat dissipation analysis between ceramic heat dissipation substrate and Metal Core pcb
With the rapid development of technology in recent years, rising awareness of global environmental protection has become a strong concern. Simultaneously, mcpcb manufacturing companies are pondering over new techniques to develop energy saving technology. Perhaps, every contemporary mcpcb manufacturer is trying for this.
Metal core pcbs are overwhelming electronic industry. In the past few years one of the emerging industries in China Expo 2010 can be seen LED technology. It is more luminous splendor, from the production upstream to downstream. Every aspect play very important roles.
For the LED luminous efficiency will decrease continuously with increasing growth in:
- the number of applications
- usage time
- high junction temperature will accelerate Movies
- affect the quality of the color temperature of the LED light induced attenuation,
- the junction temperature of the LED emission luminance exhibits inverse Relationship.
In addition, with the increase in LED die size and the development of polycrystalline LED package design, the thermal load of the LED carrier board has also doubled. Moreover, it has also increased mcpcb manufacturing companies efforts.
At this time, in addition to the heat dissipation capacity of the carrier board material, the thermal stability of the material will affect the LED product life.
Why mcpcb products are ideal?
In short, high-power LED product carrier plate material to simultaneously have:
- a high heat dissipation propertyand
- high heat resistance, and
Therefore, the sealing material of the mounting board has become a key factor.
The difference between mcpcb and thin ceramic heat dissipation substrate:
Most of the current mcpcb manufacturing markets is still based on MCPCB. The reason is low cost and good luminous efficiency at the beginning. But its heat dissipation effect is poor, and the process temperature cannot exceed 350 ℃. So it cannot be applied to high power.
- Its structure is on a5mm thick aluminum plate, with a thickness of 72μm Polymer bonded metal copper (35μm).
- To connect aluminum / copper metal and establish an insulation resistance, it is
polymer bonded with a thermal conductivity of only 0.2 ~ 0.5W / mK.It causes the overall thermal conductivity of MCPCB material to drop to 2 ~ 3W / mK.
- In addition, the presence of Polymer materials, also poor thermal stability of the substrate. A material having a probe Polymer environment at high temperature, resulting in short
risk of the road.
- The thermal stability of the Al2O3 substrate material is excellent.Providing excellent material high-temperature thermal stability and high insulation resistance.
How mcpcb manufacturing is helping LED industry?
High-power, small-size products are currently the focus of development in the LED industry. Furthermore, in the case of finer production and higher accuracy, the process capability and technology are also very important links.
Mcpcb manufacturers are developing in line with market needs and solve future product solutions. And then play the most major economic benefits. Moreover, mcpcb manufacturing companies making products more environmentally friendly, green energy to meet the needs.
Analysis and comparison of heat dissipation difference between ceramic heat dissipation substrate and Metal Core PCB
With the rapid development of technology, the awareness of global environmental protection in mcpcb manufacturing industry has risen in recent years. In addition, how to effectively develop energy-saving and energy-saving technology products has become a trend today.
As far as the LED industry is concerned, it has gradually become one of the fast-growing emerging industries in the past few years.
In the 2010 World Expo in China, it can be seen that the LED technology is even more splendid. From upstream to downstream mcpcb manufacturing, every link Are very important roles.
The luminous efficiency of LEDs will continue to decrease with the increase of use time and the number of applications. Moreover, the excessively high junction temperature will accelerate the degradation of the color temperature quality of LED light emission. So, the junction temperature is inversely proportional to the LED brightness.
In addition, with the increase in LED die size and the development of polycrystalline LED package design. The thermal load of the LED carrier board has also doubled. At this time, in addition to the heat dissipation capacity of the carrier board material, the thermal stability of the material will affect the LED product. life.
Simply put, the carrier material of high-power LED products needs to have both high heat dissipation and high heat resistance. So, the material of the package substrate becomes a key factor.
The difference between MCPCB and thin ceramic heat dissipation substrate
Most of the current market is still based on mcpcb manufacturing. The reason is low cost and good luminous efficiency at the beginning. But its heat dissipation effect is poor, and the process temperature cannot exceed 350 ℃. so it cannot be applied to high power.
Which software is used in mcpcb manufacturing?
The most powerful, advanced and easy-to-use professional PCB design software for mcpcb manufacturing.
