PCB CNC Milling Service

What is CNC PCB Milling?

CNC PCB milling uses special computer-controlled machines to cut and shape circuit boards. Unlike other ways to make PCBs, milling lets us create boards fast – perfect when you need a prototype in a hurry!

At Istar Machining, we use high-tech CNC milling machines with super sharp tools to make your PCBs exactly right. Our machines cut with ±0.025mm accuracy, which means your boards will work perfectly every time.
