At Datum we provide CNC micromachining services, producing micro milled sheet metal and foil.

Our precision, CNC milling machine produces shapes, contours, and pockets in the surface of thin metal sheet and foil. This process is perfect for producing multi-level surface heights on foils used as stepped stencils for the application of solder paste to PCB’s used in the SMT market.

Datum supplies customised micro-profiled sheet and foil ready to be laser cut to stencils, offering significantly improved levels of positional accuracy, surface finish and transition control for small geometries. A stepped stencil enables the SMT manufacturer to apply varied thicknesses of solder paste to a PCB, suitable for different size components in one pass during the screen-printing process.

Machined stepped stencils are an efficient more precise alternative to welded or chemically etched stepped stencils. In a world where micro-components are becoming smaller, having the control over the thickness and dimensions of foil depths plays a critical role in the SMT process.

With micro-CNC milling capabilities, Datum’s small parts, CNC machining expertise enables us to produce high precision, small components to micron level tolerances. We also mill steps and pockets as part of our small parts CNC machining process, a second operation performed after laser cutting that produces microscale features on your components. These processes together give you the precision and repeatability of laser cutting and micromachining and the flexibility of etching.
