Round LED Aluminum PCB for CCTV Infrared Lamps: Custom Manufacturing Solutions

CCTV infrared lamps need to work reliably in a relatively compact space. The IR LEDs generate heat during continuous operation, while the circuit board often needs to fit a specific circular or ring-shaped structure around the camera lens. For this type of application, a custom aluminum PCB can provide a practical combination of circuit integration, mechanical flexibility, and heat dissipation.

For surveillance equipment manufacturers, the challenge is not simply finding an aluminum PCB supplier. The board needs to match the camera structure, LED layout, mounting requirements, electrical design, and production requirements of the finished infrared lamp.

XingDa Group, founded in 2011, is a professional manufacturer of various circuit boards, including PCB, FPC, rigid-flex PCB, PCBA, and EMS products. Headquartered in Shenzhen, China, the company operates three production bases with a total area of more than 36,000 square meters. Its PCB manufacturing capabilities support customized requirements for customers in different industries.

For CCTV and infrared lighting projects, XingDa provides a custom round LED aluminum PCB designed for applications such as security camera IR supplementary lamps and LED monitoring fill lights.

Why Use Aluminum PCB for CCTV Infrared Lamps?

Infrared LEDs can operate for extended periods, particularly in surveillance systems that require night vision or supplementary illumination. As the LEDs continuously convert electrical power into light and heat, thermal management becomes an important part of the lamp design.

An aluminum PCB uses an aluminum metal base beneath the circuit structure. This construction provides a practical thermal path and can help transfer heat away from the LED area toward the surrounding heat-dissipation structure.

For CCTV infrared lamps, this can be useful for several reasons:

• The PCB can be designed around the camera's optical structure.
• Aluminum provides a metal base for thermal management.
• Circular PCB layouts can accommodate ring-shaped IR LED arrangements.
• Different board sizes can be developed for different surveillance camera modules.
• The PCB can be supplied as a bare board or incorporated into a PCBA project.

The actual thermal performance of a complete CCTV lighting assembly still depends on the LED components, power level, housing, heat sink, mounting method, and operating environment. Therefore, PCB selection should be considered together with the complete lamp design.

Custom Round PCB Design for CCTV Camera Modules

One of the main requirements for an infrared camera lamp is its shape.

A conventional rectangular PCB may not make efficient use of the available space around a camera lens. A circular or annular aluminum PCB can instead be designed to follow the geometry of the surveillance camera.

XingDa's product is specifically presented as a custom round annular aluminum PCB for security camera IR supplementary lamps. The manufacturer also indicates that multiple blank LED PCB sizes are available for different surveillance camera modules.

This type of design can be useful when the customer already has a camera housing and needs the PCB to fit an existing mechanical structure.

During the development stage, buyers can provide the required dimensions, LED positions, mounting holes, circuit layout, and other technical information. The manufacturer can then produce the board according to the approved design.

Product Specifications for Custom Aluminum PCBs

For buyers sourcing aluminum PCBs from China, technical specifications are an important part of supplier evaluation.

XingDa's custom round LED aluminum PCB uses 5052-H32 or 6061-T6 aluminum alloy. The listed finished board thickness ranges from 0.4 mm to 3.0 mm, while copper thickness ranges from 1 oz to 6 oz.

The available process specifications include:

These specifications provide a starting point for custom projects. The final design should be determined according to the electrical and mechanical requirements of the specific CCTV infrared lamp.

Where Round LED Aluminum PCBs Are Used

Although the product is designed around CCTV infrared lighting, its application is not limited to one specific surveillance camera model.

CCTV Security Infrared Lamps

The primary application is infrared supplementary lighting for security cameras. A circular aluminum PCB can accommodate an annular LED arrangement around the camera lens while providing a suitable metal base for heat management.

LED Monitoring Fill Lights

Infrared fill lights are commonly used to support surveillance in low-light or night-time environments. XingDa's product information specifically lists monitoring infrared fill light and night-vision auxiliary lighting as application scenarios.

For these products, stable operation over extended periods is an important consideration. The aluminum base can support heat dissipation from the IR LED area.

Custom LED Lighting Modules

The same manufacturing approach can also be applied to special-shaped LED modules, circular lamp boards, and purpose-built lighting equipment. XingDa supports either bare blank PCB production or complete PCBA service for these custom LED lighting applications.

Other Small LED Lighting Products

Round aluminum PCBs can also be considered for spotlights, indicator lamps, and other small high-power LED lighting products where heat dissipation is part of the design requirement.

Manufacturing Quality Is Important for Custom LED PCBs

For a custom PCB, the final product depends on more than the raw aluminum material.

Dimensional accuracy, circuit pattern consistency, solder mask quality, electrical performance, and surface finish all need to be controlled during production. This becomes particularly important for circular boards because the PCB must fit the corresponding housing and LED assembly.

According to XingDa's product information, its aluminum PCB production line includes raw material incoming inspection, cutting, imaging, etching, solder mask printing, AOI inspection, electrical testing, final QA, and packaging. The company states that both custom samples and mass-volume orders are supported.

For an OEM customer, this production process provides a clearer path from prototype development to repeat production.

Why Consider XingDa for Custom Aluminum PCB Projects?

XingDa Group has been manufacturing circuit boards since 2011. Its product scope covers PCB, FPC, rigid-flex PCB, PCBA, and EMS services, allowing customers to work with a manufacturer that handles different circuit board requirements within one organization.

The company is headquartered in Shenzhen and operates three production bases covering more than 36,000 square meters. Its published production information lists a monthly PCB capacity of 100,000 square meters and an FPC capacity of 12,000 square meters. The PCBA factory includes 8 SMT lines and 6 DIP lines.

For international buyers, this broader manufacturing capability can be useful when a CCTV project involves more than a single bare PCB.

Depending on the project, customers may need:

• Custom aluminum PCB fabrication
• Round or annular PCB structures
• Different aluminum alloy options
• Customized LED positions
• Bare PCB samples
• PCBA assembly
• Electrical testing
• Repeat production

Having these requirements discussed directly with the manufacturer can reduce unnecessary communication between multiple suppliers.

What Should Buyers Provide When Ordering a Custom Round LED PCB?

Before requesting a quotation or prototype, CCTV manufacturers can prepare several basic technical documents and specifications.

The most useful information normally includes:

1. PCB dimensions – outer diameter, inner diameter, thickness, and any special contours.
2. LED layout – number, position, and type of IR LEDs.
3. Circuit files – Gerber files and relevant production drawings.
4. Mounting requirements – screw holes, positioning holes, slots, or other mechanical features.
5. Copper requirements – required copper thickness based on the electrical design.
6. Surface finish – OSP, HASL, immersion gold, or another specified finish.
7. Assembly requirements – whether the project requires a bare PCB or assembled PCBA.
8. Application conditions – operating temperature, installation environment, and expected working conditions.

Providing these details at the beginning makes it easier for the manufacturer to evaluate the design and identify potential production issues before manufacturing.

A Practical Solution for CCTV Infrared Lighting

For surveillance equipment manufacturers, the PCB is only one component of the complete infrared lighting system, but it directly affects the electrical layout, LED positioning, mechanical fit, and thermal path.

A custom round aluminum PCB can be a practical option when a CCTV infrared lamp requires a circular structure and continuous LED operation. Instead of adapting a standard rectangular board to the camera housing, manufacturers can develop the PCB around the actual mechanical and optical requirements of the product.

XingDa's custom round LED aluminum PCB for CCTV infrared lamps supports different aluminum materials, board thicknesses, copper thicknesses, surface treatments, and customized board configurations. The company's broader PCB and PCBA manufacturing capabilities also provide options for customers who need to move from bare PCB samples to assembled products.

For CCTV manufacturers, security equipment companies, and LED lighting OEMs, the practical starting point is to provide the PCB drawings and application requirements. From there, the manufacturer can evaluate the board structure, manufacturing process, and production requirements for the specific project.
