Photo etching is also known as chemical milling or metal etching. This process can be either wet or dry. Wet etching is the procedure in which metal is dissolved in a chemical solution. In the case of dry etching, the material is dissolved with the help of vapor.
The entire process of photo etching is a combination of basic etching and photolithography. In the photolithography process, patterns are created by the reaction of enzymes on molecules or by using photoresist covered substrates. This way photo-resist is developed while the substrate is exposed to ultraviolet light. Then the substrate is etched. The photoresist helps in shielding the parts of the substrates that are not required to be etched. This is a very useful method these days for creating finger stocks or circuit board shields.
The method has managed to set a wide market for itself mainly based on its functionality. This procedure is now adopted in different manufacturing units, the electronic and metal industries and in certain cases in the aircraft & aerospace divisions, as well. This method is also known as photo milling or photo etching. The electronic manufacturing industry has used this process extensively in its quality and high level of precision.
The entire method of photo etching is not so difficult. It is indeed very useful for metal components, especially when voluminous work is needed to be produced. The procedure helps in creating stencils, circuit boards, mechanical models, etc. The entire method of photo etching demands a considerable amount of attention and subtle control. The process is quick and requires a very low cost set up. Various metals, such as stainless steel and alloys with corrosion resistance power can be used for etching. Even very thin metals or foils, hard or brittle materials can undergo this process.
Applications of photo etching
Aerospace and Defense
Photo etching service is required in these sectors while building helicopters and military combat to commercial airlines. The reason for using chemical milling services in these sectors is that they offer low-cost tooling, and high accuracy, which is crucial. A highly efficient service provider can offer you various surfaces finishes, on request.
This photo-etching service is required extensively in the ever-evolving automotive sector. This is the sector where precision technology is most required for getting error-free vehicles on the roads. Only efficient photo etching would ensure that ever-higher levels of precision and tighter tolerances are maintained to improve operational efficiency in this sector.
With communication technology changing like never before, there is a constant demand for communication products that are photo-etched in a precise manner. Use quality services, as communication media too has a huge impact on the success of the business, and even our general lives.
Photo etching services have helped in making precision electronic products that have become smaller but loaded with more and more advanced features. Only a good company can offer you fully-finished, formed, plated and assembled high precision components like RF shielding and circuit board shield.
