Introduction to PCB Laser Cutting

PCB laser cutting is an advanced technique used for precise cutting and engraving on various materials used in the creation of printed circuit boards (PCBs). It offers numerous benefits including high precision, reduced waste, and faster processing times. This method has gained popularity as it accommodates a wide range of materials while maintaining integrity and accuracy.

Materials Compatible with PCB Laser Cutting

The PCB laser cutter is capable of working with multiple materials, each with specific characteristics that determine the optimal cutting parameters. The primary materials include:

FR-4

FR-4 is a widely used material in PCBs due to its good insulation properties and thermal resistance. Laser cutters can process FR-4 with a laser power setting of approximately 20-30 Watts and a cutting speed of 300-500 mm/s to ensure clean and precise cuts without burning the edges.

Copper

Copper is commonly used for conductive traces in PCBs. Laser cutters can engrave copper layers with a power setting of 40-50 Watts and a speed of 200-400 mm/s. The technique requires precise control to avoid excessive heat that can damage the surrounding material.

Polyimide

Known for its flexibility and thermal stability, polyimide is frequently utilized in flexible PCBs. A laser power of 10-20 Watts and a speed of 500-800 mm/s can efficiently cut polyimide without compromising its structural integrity.

Aluminum

Aluminum is used mainly for its lightweight and conductive properties. Cutting aluminum requires higher laser power, typically around 50-70 Watts, and speeds of 100-200 mm/s to achieve clean cuts without burrs.
