The milling machine

The LPKF ProtoMat® S42 introduces a new entry-level circuit board plotter for in-house rapid PCB prototyping. This compact system provides precision and performance for quickly and easily milling and drilling circuit board prototypes in a single day. In-house PCB prototyping eliminates production delays and the high cost of outside vendors, reducing a product's development time and time-to-market dramatically. Design data also remains securely in-house and under control. The S42 in particular is a perfect entry-level tool for educational and other settings where economy is a critical issue.
