Microchannel Machining Solutions for Non-Diamond Materials

Product Details

MICROCHANNEL MACHINING CONTRACT MANUFACTURING SERVICE

Extending Our Laser Micromachining Expertise to More Materials

In addition to diamond materials, we extend our precision laser micromachining technology to contract manufacturing services for microchannels in non-diamond materials, including metals, ceramics, sapphire, and glass. We help customers directly create microchannel cooling structures on existing substrates to meet the diverse material requirements of high-power components for active cooling, without being restricted to a single material.

CORE TECHNOLOGY CAPABILITY

Core Technology Capabilities

Precision Laser Micromachining: Ultrafast pulsed lasers, such as femtosecond lasers, are used to ablate, cut, and form microstructures. No mask is required, enabling high machining precision and a small heat-affected zone for a wide range of hard, brittle, and difficult-to-machine materials.

Broad Material Compatibility: Compatible with metals such as copper and aluminum; ceramic substrates such as alumina and aluminum nitride; and optical materials such as sapphire and glass. Laser parameters and machining paths are adjusted according to substrate characteristics.

Versatile Microchannel Designs: Straight, serpentine, tree-branch, and other channel geometries can be designed according to cooling requirements to optimize coolant flow paths and heat-transfer efficiency.

Customized Dimensions and Density: Channel width, depth, and spacing can all be flexibly adjusted according to the customer's hotspot distribution and power-density requirements.

TECHNICAL ADVANTAGES

Technical Advantages

Greater Material Selection Flexibility: Customers can select the most suitable substrate for microchannel machining based on cost considerations, existing supply chains, or specific application requirements, without being limited to diamond materials.

Rapid Prototyping: With no need for tooling or masks, our process is ideal for rapid validation and prototyping of small-batch, customized patterns.

One-Stop Contract Manufacturing: From material evaluation and channel design to machining and forming, we provide a complete contract manufacturing process, lowering the barrier to establishing an in-house production line.

APPLICATIONS

Applications

Active liquid-cooling microchannel machining for metal heat-dissipation substrates (copper and aluminum)

High-power packaging thermal-management applications for ceramic substrates (alumina and aluminum nitride)

Precision microstructure machining for optical and semiconductor materials (sapphire and glass)

Other applications requiring microchannels or functional microstructures to be fabricated in non-diamond materials

PROCESS CAPABILITY

Our Process Capabilities

From substrate characterization and laser channel design to microstructure forming and quality inspection, we provide one-stop contract manufacturing services for microchannels in non-diamond materials. We can also customize channel geometry and machining specifications according to the customer's substrate type, hotspot distribution, and cooling-system design.
