Transportation lighting has become an important application market for LED as an illumination source. At the 2010 Shanghai International New Light Source & New Energy Lighting Forum's “New Light Source and Transportation Lighting Transformation” summit, guests from the semiconductor lighting field and LED related applications companies The application of semiconductor lighting in tunnel lighting, rail transit lighting, automotive lighting, etc. has been heatedly discussed, and the good development prospects of various markets have become the focus.

At present, LEDs have been applied to the interior and exterior of automobiles. "Especially in automotive interior lighting, the application of color LEDs is very mature, such as for instrument panels, backlight switches, car reading lights or head-up display systems, or cars. The 'Color-ON-Demand' feature allows automakers to differentiate themselves from other competitors by using their own unique recognition colors, or to use color to distinguish between different series of products." OSRAM Optoelectronics Zhong Jiecong, Marketing Director of Asia Pacific, Semiconductor Asia Ltd. said.

The external application of the car is also constantly developing. Zhu Minghua, the director of the electronic technology department of Shanghai Xiaohao Auto Lamp Co., Ltd., has introduced LEDs, such as brake lights, tail lights, turn signals, reversing lights, high-position brake lights, etc. The taillights and high-position brake lights are widely used. As a vehicle headlamp illumination, due to the need for high-power LEDs, it is subject to technology and LED cost-effectiveness, especially in the fields of optics, electronic control, and thermal management. It takes three to five years for the industry to become popular. It is also only available on some luxury high-end models.

Zhu Minghua believes that in addition to the current application of taillights, high-position brake lights, etc., future turning lights, reversing lights will also use LEDs on a large scale. In 2010, the market size of domestic LED automotive lamps may exceed 1 billion yuan, and an annual output value of 3 billion yuan may be formed within 5 years. Zhong Jiecong said that according to iSuppli's “2010 LED Special Report” released in 2009, it is estimated that by 2013, about 95% of new cars in the world will use LEDs in one or more taillights.

At present, the sales of LED automotive lighting application market is about 10% annual growth rate, but the proportion of domestic LED automotive lamps is not high. Zhu Minghua said that the models with relatively large LED usage are concentrated in the mid- to high-end auto companies, and these auto companies generally have restrictions on the LED brand, and domestic LED companies are more difficult to enter their supply chain. In addition, compared with international famous brands, domestic LEDs may have more problems in terms of life and uniformity of sorting. At the same time, the market regulation of auto lamps itself is strict, the threshold is relatively high, and automobiles are sold as luxury consumer goods. For one-to-one customers, any quality problems will cause complaints. Domestic LEDs have no chance to go through this market for a long time, and it is difficult to meet the LED standards for vehicles. "Automotive lamps are very professional fields. It is necessary to do LED car lamps. Whether it is car lamps or LED companies, it is very difficult to go it alone. It is necessary for car lamps companies to fully communicate with LED companies, especially in LED cars. The development of headlights." Zhu Minghua said.

For the development of LED automotive lamps, Zhong Jiecong believes that off-vehicle applications such as taillights, high-position brake lights, turn signals, side lights, low beam lights and high beam lights require different lumen values. In fact, the lumen value depends on the system efficiency of the optical components used. Therefore, before LEDs become standard headlights, more extensive development of the entire system is required, such as more sophisticated thermal management, optimized high-resolution optical components, and electronics for connecting automotive electronic systems.

Although there are still some problems to be solved, LEDs have the advantages of small size, vibration resistance, energy saving, long life and the like, and at the same time give designers a broader design space, which are the elements to increase the application of LEDs in and out of the car. With the continuous improvement of product technology and the continuous expansion of product categories, the future of automobiles will develop in the direction of safety and intelligence.

Metal PCB

Metal PCB, Metal Core PCB, thermal PCB -  whichever name you prefer, they are all boards which use a base metal material as the heat spreader portion of the Circuit Board.

Base metals in the BentePCB are used as an alternative to FR4 or CEM3 boards for the ability to dissipate heat away from critical board components and to less crucial areas such as the metal heatsink backing or metallic core.

Metal Core PCB Materials and Thickness

The metal core of the thermal PCB can be aluminum (aluminum core PCB), copper (copper core PCB or Heavy Copper Pcb) or a mixture of special alloys. The most common is an aluminum core PCB.
The thickness of metal cores in PCB base plates is typically 30 mil - 125 mil, but thicker and thinner plates are possible.

BentePCB copper foil thickness can be 1 - 16 oz

BentePCB can be advantageous to use for their ability to integrate a dielectric polymer layer with a high thermal conductivity for a lower thermal resistance.
Metal core PCBs transfer heat 8 to 9 times faster than FR4 PCBs. BentePCB laminates dissipate heat, keeping heat generating components cooler which results in increased performance and life.

Metal Core PCB uses - LED Applications and More 

Applications that generate a large amount of heat often cannot be adequately cooled using just traditional fans. Conductive cooling through metal core PCBs are an ideal production option.
BentePCBs are most widely found in LED technologies, as they reduce the number of LEDs required to produce a specific illumination. Light emitting diodes release a great amount of heat in applications such as:

• Back light unit applications
• Street safety applications (streetlights, lighting, etc.)
• General lighting applications
• System automotive LED applications
• Power converters:  telecom, industrial, high voltage regulator, power supplies
• Hybrid/electric motor control applications
• Photovoltaic

Using a metal core PCB in these LED products and applications help to greatly reduce the heat emitted.
Other applications that are ideal for BentePCB integration are solar panels and motion control applications. We can also combine metal core with our  HDI PCB  technology.
