What do you mean by micromachining?
Definition of micromachining : the removing (as in drilling, planing, or shaping) of small amounts of material (such as metal) by action other than that of a sharp-edged tool micromachining done with an electron beam.
What are the different types of micromachining?
ELECTRIC DISCHARGE MICROMACHINING (EDMM)
What is CNC micromachining?
Mechanical micromachining is the process of high-precision manufacturing of small components needed for specific purposes. The process is carried out by a high-precision CNC machine using advanced technologies such as micro milling and micro turning.
Where is micromachining used?
Surface micromachining is used to pattern the backside as well as to create a metal electronic sensing circuit on the frontside of the wafer. Below is the process used to fabricate this MEMS pressure sensor. A thin film of silicon nitride is deposited onto both sides (frontside / backside) of the wafer.
What is bulk and surface micromachining?
Bulk micromachining is a process used to produce micromachinery or microelectromechanical systems (MEMS). Whereas surface micromachining creates structures on top of a substrate, bulk micromachining produces structures inside a substrate.
Why is micromachining needed?
Micromachining offers a method for single process machining for smaller parts, so milling and turning can be done on the same machine. This reduces lead time and allows parts to be machined more efficiently. Even larger parts can be machined with greater accuracy and speed on machines used for micromachining.
Why do we need micromachining?
What is laser micromachining?
Laser micromachining is a versatile process and is used widely for machining plastic, glass, metal as well as preparing thin foils. The process comprises different mechanisms like cutting, drilling, marking, turning, threading, etc.
What is bulk micromachining surface micromachining?
How does surface micromachining differ from bulk micromachining?
Unlike surface micromachining, which uses a succession of thin film deposition and selective etching, bulk micromachining defines structures by selectively etching inside a substrate. Whereas surface micromachining creates structures on top of a substrate, bulk micromachining produces structures inside a substrate.
