4. Advanced Materials:
   • Innovations in PCB substrates, such as high-frequency materials and heat-resistant laminates, enhance performance in demanding applications.
   • These materials are critical for automotive electronics, 5G infrastructure, and aerospace systems.
     
5. Automated Optical Inspection (AOI):
   • AOI systems use cameras and software to detect defects in PCBs during production.
   • This technology ensures high-quality standards while reducing manual inspection time.
     
6. Laser Drilling and Etching:
   • Precision laser technologies enable the production of microvias and intricate PCB designs.
   • This capability is essential for HDI and multilayer PCBs.
     
7. Sustainability Practices:
   • Eco-friendly soldering techniques, lead-free processes, and recycling initiatives are gaining traction.
   • Many manufacturers are adopting green practices to reduce environmental impact.
