The LPKF ProtoMat S103 circuit board plotter for producing PCB prototypes and small batches is configured specifically for RF and microwave requirements. The touchless, pneumatic depth limiter further allows delicate surfaces, soft and flexible substrates to be processed. The ProtoMat S103 also carefully depanels irregular shaped flexible circuit boards from larger boards.

2.5-dimensional operation with Z-axis control

The sophisticated Z-axis drive makes the ProtoMat S103 perfect for finishing front panels and housings as well as depth milling microwave PCBs. Even machining populated PCBs is no problem at all.

100.000 rpm spindle motor

The ProtoMat S103 is extremely fast and accurate with a spindle speed of 100.000 rpm, a max. travel speed of 150 mm/s and a resolution of 0.5 μm. This ensures the accuracy required for drilling and milling ultra fine structures – especially for high-end applications in the RF- and microwave field.


CircuitPro turns raw CAD data into a dataset for populating the circuit board with soldering paste with no additional expense. The software wizard guides the user through the individual process steps. An internal computation accounts for the pad shape and size to ensure each pad has the right amount of soldering paste. This is further achieved through proven process parameters. The paste is applied with the built-in dispenser, all without having to convert the machine.
