 Aluminum Core PCB for LED application

Aluminum is superior in heat conduction, corrosion resistance, lightweight and cost.

MITS prototyping machines can resolve the technical challenge
Our prototyping machines overcome challenges with precisely controlled motor driven Z-axis, highly accurate and ruggedized mechanism, flatness of the work          table, and cross angular accuracy of X,Y and Z-axis.
High torque spindle motor to ensure counter routing of Aluminum base. Smooth running of routing is performed by soft control of powerful spindle motor unit.

Recommended model

Example of processing method

Millig Couter Routing
Tool HF Milling Bit Tool Aluminum Bit
Milling Method Incremental Milling Routing Method 3 stage step milling
Spindle Speed 30,000 RPM Spindle Speed 40,000 RPM
Head Travel Speed 6mm/sec                         (0.3mm HF Milling Bit)    12mm/sec (0.5mm HF Milling Bit) Head Travel Speed 2mm/sec                         (1.0mm Aluminum Bit)

* Above milling conditions are shown just as a rough standard.

Technical Challenges

Extremely accurate cutting depth control is required to correctly mill the copper layer without                         breaking insulation/adhesive layer.
