What is the Automotive LED aluminum substrate byd?

In short, this is a metal -based print circuit board used in the lighting of byd vehicles. It adopts the aluminum substrate to increase heat dissipation and mechanical strength. And the copper layer is isolated through an isolated layer, to ensure that the LED current is well distributed. This structure supports high lumen density, meanwhile, maintaining the temperature of the intersection remains low, ensuring the long -term stability of brightness and color.

Compared to traditional FR4, aluminum substrates do heat faster, which allows LEDs to be placed in high density for concise space. In addition, a metal base increases the stiffness and tolerance of vibration. It adapts to the heat shock of the vehicle and the vibration of the road while driving.

What are the features of the Automotive LED aluminum substrate byd?

• Very good thermal discipline: Low heat resistance keeps the temperature of the LED intersection low, lumen and stable color, and long life.

• Safe Electricity: Very isolated layers ensure the ability to load electrical pressure, and one -sided layout meets the distance and creepage requirements.

• Mechanical strength: The aluminum substrate feature of WARP resistance and shock resistance, which is useful for lenses and brackets.

• Stable manufacturers: Clean the copper layer, good solder paste, and finally, a low level of re -work.

• Cost efficiency: This reduces the layers and processes for a single layer layout, and the tool is simple; Finally, high yield rates.

What are the types of Automotive LED aluminum substrates byd?

The following is a type of Aluminum Automotive BYD aluminum substrate.

• Aluminum substrate one side: The most common choice for lamps and strips DRL.
• IMS isolated made: The thickness of the isolated layer or damage pressure will be higher.
• IMS High-thethmal: Dielectric engineered for lower thermal resistance, which is good for compact space and high flux.
• Hybrid board: The LED area uses aluminum, and the control circuit area uses FR4.
• Rigid-flex circuit board: Adoption of aluminum substrates for segments, connected to flexible cables, suitable for bent lighting strips.

What ingredients are used in one side of the aluminum aluminum substrate?

• First, the basis of aluminum in a thickness of 1.0-2.0 mm with 5052 or 1060 classes is often used.

• Second, the thermal conductivity insulation layer is 75-150μm.

• Third, copper foil in 35-105 μm.

• The protective layer of the solder paste and the white surface layer will increase optical gain.

• Finally, it should be mentioned that surface treatment is OSP or Enig.

It is very helpful to note that it is necessary to consider thermal conductivity, isolation, and costs when selecting materials.

What is the function of the aluminum substrate board supported by a single layer board for the LED lighting industry?

The main functions include thermal discipline, electrical conductivity, and mechanical structure support (which includes lenses and brackets).

• Thermal Discovery: Through the basis of aluminum and aluminum layers to realize rapid thermal transmission.

• Electricity Conductivity: The copper foil circuit is used in the current transmission.

• Mechanical Support: It provides a rigid structure for LED modules, lenses, and heat sinks, especially for car applications.

In a car, these functions are the center of attention. A single layer board is a practical foundation in the application.

How does the aluminum LED board substrate in Automotive lighting byd?

It is important to understand the core mechanism that increases the efficiency of thermal dissipation and operational stability.

First, there is a separate structural design, which is an aluminum nucleus, isolated layer, and copper foil circuit layer.

• The aluminum core, such as aluminum 6061 alloys, offers mechanical support, which is high in thermal conductivity until 200-235W/m · k. Very useful to do the heat where the LED chip is produced.
• In addition, through the isolation layer to ensure electrical insulation, meanwhile to maintain heat conductivity, with a coefficient of heat conductivity 1-3W/m · k.
• Finally, the coating of the copper foil circuit through ETSA to form a circuit, which connects the LED chip and the driving circuit.

Optimizing the thermal discipline routes is very important.

• Heat passes through layer by layer: LED chip → Isolation layer → aluminum substrate → heat sink.

• Compared to traditional FR4, heat resistance is reduced by more than 50%.

The design strengthened by the car level is also famous.

• This structure rejects corrosion in the environment of humidity and salt spray and vibration resistant, with the aluminum nucleus provides a rigid layer of 1.0 mm.

Finally, it is worth noting about the benefits of integration.

• The single layer deisgn simplifies the assembly, and reduces the heat sink and interface, reducing weight and costs.

This design helps maintain the age of more than 50,000 hours even if in high temperatures, high humidity situations.

What is the process of making an automotive LED aluminum substrate byd?

10. QA: Complete QA and Packing

What is the main application of aluminum LED board substrate in LED Byd lighting?

The core application is as follows:

• Headlamps and DRLS: High LED Flux Array with the Right Optics. This avoids lumen depreciation because of the high heat conductivity of the aluminum substrate doing the heat of the LED chip quickly.

• Fog lights: The house is compact with a strong hot path. Good for wet and cold cycles.

• Power and Control Module: For example, electricity adjustment devices or control devices are for power transfer, such as DC / AC inverters. Aluminum has a high current loading capability to a pressure resistance of 4500V, and has low heat resistance, which mostly increases reliability.

• BACK LIGHT/INTERIOR LIGHTS: It meets the thinner and lighter weight needs through high density assembly than the SMT process.

It is important to note that the level of heat conductivity of the aluminum substrate board is more than 6.7 times the FR4. Therefore, it will be suitable for high -power LED lighting.
