Cutting Tools for Electronics & Semiconductors
Micro tools for micro work.
PCB routing, ceramic substrates, heat-sink finishing — JIAYI micro carbide end mills and drills cut copper, aluminum nitride and alumina cleanly at diameters from 0.1 mm.
The challenge
Electronics machining is a different physics: tiny diameters, fragile substrates and zero tolerance for vibration. A 0.1 mm tool has no rigidity to spare — runout, chatter or a chipped edge shows up immediately as a broken trace or a cracked ceramic. Heat sinks need flat, burr-free fins; jigs need micron-level repeatability.
JIAYI solutions for electronics & semiconductors
