Precision Micromachined Elements

The progressive miniaturization in electronics, semiconductor processing and manufacturing of medical instruments is characterised by smaller and smaller structures in addition to the demand for highest precision by way of surface high quality, absence of burr, and supplies residues. 14. Floor Micromaching • In contrast to Bulk micromachining, where a silicon substrate (wafer) is selectively etched to produce structures, floor micromachining builds microstructures by deposition and etching of different structural layers on top of the substrate • Generally polysilicon is usually used as one of the layers and silicon dioxide is used as a sacrificial layer which is removed or etched out to create the mandatory void within the thickness path • The main advantage of this machining process is the possibility of realizing monolithic microsystems during which the electronic and the mechanical elements(features) are built in on the same substrate.

Makino precision micro machining facilities are designed with options akin to advanced spindle temperature control, unique EDM advancements and rigid machine building that enhance your shop’s micro machining performance. This machine can mill metal, titanium, aluminum and virtually all different millable supplies. The Electro Discharge Machining (EDM) is a thermo-electric machining process that shapes the work piece by materials elimination or erosion. It is because an enormous class of engineering materials (metals, semiconductors, ceramics, optical glasses and plastics) might be processed and a large number of surfaces with optical, digital or mechanical functions can be generated.

The rationale lies in the fact that in micro-machining with high power electron beams the penetration of electrons in the surface layers are in depths of many microns and tens of microns, and because the power is transferred to the atoms in the form of warmth over a relatively large zone.
