Diamond-Coated Tools: The Solution to PCB Milling Challenges

In recent years, PCB manufacturers have faced increasing challenges in machining high-performance materials used in PCB assembly across the telecommunications, military, medical, and automotive sectors.

The introduction of halogen-free materials, IMS, and laminates with various types of fillers has significantly impacted the performance and lifespan of conventional carbide tools traditionally used for PCB manufacturing. While these advanced materials ensure excellent technical properties for the final products, they are highly abrasive, leading to faster tool wear.

As a direct result, manufacturers have experienced reduced machining parameters and shorter tool life, causing a significant increase in production costs and machine downtime, negatively impacting overall productivity.

To address these challenges, many manufacturers have transitioned to using diamond-coated tools, which offer:

✅ Significantly longer tool life compared to carbide tools, reducing the frequency of tool changes.
✅ Consistent cutting quality even on abrasive materials, minimizing defects and rework.
✅ Optimized feed rates and cutting speeds, reducing cycle times.
✅ Lower overall production costs, thanks to reduced machine downtime and more efficient tool management.
