Etching Chemicals Market Segmented By type such as Hydrofluoric acid, Ferric chloride, Cupric chloride, Hydrochloric acid, Sodium hydroxide, Nitric acid, Ammonium persulfate, Ammonia and Ammonium chloride with application such as Chemical etching, Photo-chemical etching and Electro-chemical etching
The process in which undesired parts of a component are dissolved in chemicals such as acids, bases or others, for yielding desired shape is known as chemical etching or chemical milling. The desired part is protected by masking it with a removable material, for example polymer or rubber, which is inert or resistant to the chemicals used for etching and also gets easily adhered to the desired part.
The components such as metals, glass or semiconductors can undergo such an etching process. The process is mainly used in fabrication of components as well as where micromachining to produce tiny sized components is done. Etching chemicals has applications in fabrication of printed circuit boards (PCBs), integrated circuits (IC), microprocessor, semiconductors, radio frequency (RF) shield, lead frames, contacts, miniature antennas, optical apertures, etc. through chemical machining.
Hence, the end users would include industries of electronics, aerospace, automotive and others. The chemicals used for etching are called etchants and selection of these etchants depend on the material to be etched.
Hydrofluoric acid is used to etch silica, titanium and glass, while for aluminum components, sodium hydroxide is used; ferric chloride, hydrochloric acid and nitric acid are used for steel etching; cupric chloride, ferric chloride, ammonium persulfate and ammonia are used for copper and its alloys, ferric chloride is also used for iron based alloys and alkaline etchants for fabricating Printed Circuit Boards (PCBs).
There is tremendous growth as well as demand for electronics worldwide. Also, urbanization and globalization, which lead to the development of aerospace and emerging technologies, has in turn propelled the growth of automotive companies. In each of these areas, use of metals and alloys, semiconductors and glass are done for manufacturing the components.
This is the main driving factor behind chemical etching market, which would ultimately drive the market for etching chemicals in future. For fabrication of smaller or fragile components, precision is very important, which is very well accomplished by chemical machining even to produce complex components.
Also, this is a fast and inexpensive process, owing to which market for chemical machining is growing rapidly. Such features have increased adoption of chemical machining over other processes such as stamping and laser cutting, which may damage the final desired component.
Variety of etching chemicals are used in chemical machining. These etching chemicals are corrosive that may cause damage to the equipment, and after component etching, the disposal of potentially harmful by-products is also a major problem. These disadvantages may affect the etching chemicals market.
Again, it is important to note that along with increase in demand for electronics, it has also elevated the amount of e-waste. There are certain solutions for e-waste disposal or recovery of metals, which also include chemical etching process. This factor is expected to bolster the market of etching chemicals over the forecast period.
