Its superior characteristics make it a preferred choice in industries such as aerospace, defense, automotive, and telecommunications, where reliability and top-notch PCB materials are paramount.

General Information of Ventec VT-4B5 PCB Materials

The Ventec VT-4B5 PCB material is a type of laminate used in the construction of printed circuit boards (PCBs). Here is some general information about the VT-4B5 material:

1. Thermal Conductivity: The VT-4B5 material has a thermal conductivity of 4.2W/mK. Thermal conductivity refers to the material’s ability to conduct heat, and a higher value indicates better heat dissipation properties.

2. Ceramic Filled: The VT-4B5 material is ceramic filled, which means that it contains ceramic particles or fibers within the laminate. Ceramic fillers can enhance the mechanical strength and thermal stability of the material.

3. Halogen Free: The VT-4B5 material is halogen-free. Halogens, such as chlorine and bromine, are commonly used in flame retardants but can release toxic gases when burned. By being halogen-free, the material reduces the potential health and environmental hazards associated with halogen emissions during PCB manufacturing or in case of a fire.

4. Flammability: The VT-4B5 material has a flammability rating of UL94 V0. UL94 is a standard for evaluating the flammability of plastic materials, and a V0 rating is the highest level of flame retardancy. V0 indicates that the material has passed the vertical burning test and self-extinguishes within a specified time after the ignition source is removed.

5. MOT (Maximum Operating Temperature): The VT-4B5 material has a maximum operating temperature (MOT) of 130˚C. This means that the material can safely operate at temperatures up to 130˚C without experiencing significant degradation in its electrical or mechanical properties.

Overall, the Ventec VT-4B5 PCB material offers good thermal conductivity, is ceramic filled for enhanced properties, is halogen-free for safety and environmental considerations, has a high level of flame retardancy, and can operate at temperatures up to 130˚C.

Application of Ventec VT-4B5 PCB Substrates

The Ventec VT-4B5 PCB substrate can be used in various applications where high thermal conductivity, ceramic fillers, halogen-free properties, flame retardancy, and a maximum operating temperature of 130˚C are required. Here are some specific applications where the VT-4B5 substrate can be utilized:

1.Ultra Bright LED Substrate:

The VT-4B5 material can be used as a substrate for ultra-bright LEDs (Light Emitting Diodes). LEDs generate heat during operation, and the high thermal conductivity of VT-4B5 helps in efficient heat dissipation, ensuring proper performance and longevity of the LEDs.

2.Power Conversion:

The VT-4B5 substrate can be employed in power conversion applications. Power conversion circuits, such as DC-DC converters or AC-DC converters, can generate significant heat. The high thermal conductivity of VT-4B5 aids in dissipating heat, preventing overheating and maintaining the efficiency of power conversion systems.

3.PDP, LED, Regulator for TV:

The VT-4B5 material can be used in the construction of printed circuit boards for Plasma Display Panels (PDPs), LEDs, and regulators used in television sets. These components often require good heat dissipation, and VT-4B5’s thermal conductivity can help in managing the heat generated during their operation.

4.Monitor Drives:

VT-4B5 can be utilized in the manufacturing of printed circuit boards for monitor drives. Monitor drives, which control the display functions in monitors, can benefit from the high thermal conductivity and thermal stability of VT-4B5, ensuring reliable operation and preventing overheating.

5.Rectifier, Power Supply:

The VT-4B5 substrate can be employed in rectifier and power supply applications. Rectifiers convert alternating current (AC) to direct current (DC), and power supplies provide regulated power to various electronic devices. These applications often involve components that generate heat, and VT-4B5’s high thermal conductivity can help in managing the heat dissipation requirements.
