What is the full form of LIGA?
LIGA is a fabrication technology used to create high-aspect-ratio microstructures. The term is a German acronym for Lithographie, Galvanoformung, Abformung – lithography, electroplating, and molding.
Is LIGA a additive process?
LIGA is an additive manufacturing process which is used to manufacture complex and intricate 3-D micro-parts having submicron size and high aspect ratio. It is used for following applications: Micro-mechanical parts: micro-gears, micro-motors, micro-actuators, and micro-nozzles for variety of application.
What are the advantages of LIGA process?
The major advantages of the LIGA process are the high aspect ratios made possible and therefore the larger heights of the pieces, very sharp vertical sidewalls as well as the possibility to produce three-dimensional structures by using a sacrificial layer as described above.
For what purpose LIGA process is used?
The LIGA-process is used to manufacture micro structures by deep X-ray lithography. LIGA is the german acronym for lithography, electroplating and moulding (Lithographie, Galvanik und Abformung).
What does LIGA mean in English?
league
noun. league [noun] a union of persons, nations etc for the benefit of each other. league [noun] a grouping of sports clubs for games.
Is LIGA a word?
LIGA is a German acronym for Lithographie, Galvanoformung, Abformung that describes a fabrication technology used to create high-aspect-ratio microstructures.
What’s UV LIGA process?
UV- LIGA process uses a polymer resist sensitive to UV-rays, which can be patterned using lithography techniques. After development of the resist, 3-dimensional structure with trenches is left behind on a conductive substrate into which the metallic struc- tures are electroplated.
What are the advantages and disadvantages of LIGA process?
Advantages: small surface roughness, resulting nickel tool has a good surface chemistry for most polymers. Drawbacks: slow growth rate of nickel in the electroplating process (10-100µm/h), high stress levels in thick nickel layers, radial dependency of the growth rate (unwanted difference of structures height).
Which one of the following is the most common form of radiation used in LIGA?
Ultraviolet radiation is the most common form of radiation which is used in photolithography. Due to the most common use of ultraviolet radiation photolithography is also commonly called as UV lithography.
