FR4 CNC Machining
In addition to conventional PCBs, CNC-machined FR4 sheets are also used for insulation spacers, test fixtures, and electronic device supports. Optimized tool paths enable efficient processing of complex contours and special-shaped holes, such as mounting plates with locating slots or heat dissipation window structures.
Description
FR4 sheets are precision-milled using CNC milling, achieving a hole placement accuracy of ±0.1mm and smooth, burr-free edges. Using specialized PCB milling cutters and optimized feed speeds, we minimize copper foil warping and substrate delamination, making this process ideal for low-volume, high-precision circuit board prototyping, such as cutting and slotting RF and high-frequency boards.

High-speed CNC machining parts
CNC cutting parameters are adjusted for FR4 sheet thicknesses (0.2mm-3.0mm) to ensure no chipping at the interface between the glass fiber layer and the resin. The processed boards can be directly soldered without any additional processing. For boards requiring impedance control, CNC milling can precisely control line width and spacing, offering greater flexibility than traditional etching processes.
