Drilling and routing of composites and non-ferrous materials for printed circuit boards (PCB) industry

Composites and non-ferrous materials offer interesting properties in the PCB industry. However, these materials require intricate handling to prevent defects and ensure PCB integrity. Posalux dives into the complexities and solutions of working with these advanced materials in high-tech electronics.

Drilling and routing of composites and non-ferrous materials application overview

In the PCB industry, drilling and routing of composites and non-ferrous materials pose distinct challenges. Delamination in composites can jeopardize board integrity, while the abrasive nature of these materials accelerates tool wear, increasing operational costs. Factors like fiber pullout and heat generation further complicate the process, sometimes altering material properties. Non-ferrous materials like copper can produce burrs, necessitating additional finishing, and inconsistencies in composites make consistent drilling tricky. Additionally, there's a risk of chemical reactions between certain materials and the coolants used. Manufacturers must stay adaptive, investing in specialized equipment and refining their methods for optimal PCB production.

Mechanical Micromachining technology to perform these results

Mechanical micromachining, commonly known as micromachining, is a specialized manufacturing technology that involves the use of micro tools, such as micro-endmills or drillbits, with geometrically defined cutting edges. This subtractive fabrication process crafts devices or features with dimensions in the micrometer range. It mirrors traditional machining in approach but operates on a distinctly smaller scale, necessitating specialized equipment and techniques to define microscale structures or components. Mechanical micromachining provides:

  • Flexibility
  • Cost-effective solution for small-batches
  • Complex geometry
  • Reduced waste
  • Integration
  • Scalability
  • Direct production
