1. Technical Superiority of the TBS-LAD-860 Laser Drilling System

The TBS-LAD-860 is engineered specifically for processing challenging substrate materials like aluminum, which is prized for its excellent thermal conductivity but notoriously difficult to drill with traditional methods.

1.1. Core Technical Specifications

Our TBS-LAD-860 system incorporates several groundbreaking features that set it apart from conventional drilling equipment:

• Laser Source: A specialized 860nm, 1C, fiber-coupled laser diode system provides the ideal wavelength for aluminum material processing, delivering superior absorption characteristics for clean, precise results.

• Beam Quality: With a beam divergence of 0.22 NA and advanced beam shaping optics, the system achieves an exceptionally focused spot size capable of creating microvias as small as 50μm in diameter – essential for today’s HDI PCB designs.

• Processing Speed: The system’s high-speed galvanometers and precision staging enable drilling rates of up to 500 holes per second on aluminum substrates, dramatically increasing throughput compared to mechanical drilling .

• Positioning Accuracy: Incorporating a high-precision image recognition and positioning system with automatic target recognition, the TBS-LAD-860 achieves remarkable positioning accuracy of ±3μm , ensuring perfect alignment with your PCB panel layout.

• Cooling System: An integrated closed-loop cooling system maintains optimal laser temperature with ±0.1°C stability , ensuring consistent processing quality and extending laser lifespan – a critical consideration for high-volume production environments.

2. Solving Aluminum PCB Manufacturing Challenges

Aluminum-based PCBs present unique manufacturing hurdles that conventional drilling methods struggle to overcome. The TBS-LAD-860 is specifically engineered to address these challenges head-on.

2.1. Overcoming Traditional Aluminum Drilling Limitations

Traditional mechanical drilling of aluminum PCBs faces inherent limitations that impact both quality and cost:

• Eliminating Mechanical Stress: Mechanical drilling exerts physical pressure on the substrate, often causing deformation, delaminação, or burring of the delicate aluminum material . The TBS-LAD-860’s non-contact laser drilling process completely eliminates these issues.

• Solving Tool Wear Problems: Aluminum’s properties cause rapid wear of mechanical drill bits, requiring frequent replacement and resulting in inconsistent hole quality over time . Our laser solution maintains consistent performance without degradation, ensuring uniform quality throughout production runs.

• Preventing Thermal Damage: Unlike some laser systems that can generate excessive heat, the TBS-LAD-860 utilizes optimized pulse parameters that create a “cold processing” efeito, minimizing the heat-affected zone (HAZ) to less than 10μm around each via . This preserves the integrity of the aluminum substrate and adjacent circuitry.

The transition to laser technology for aluminum PCB drilling represents more than just an incremental improvement – it’s a fundamental transformation in manufacturing capability that enables new design possibilities.
