VIN etching uses a variety of methods, commonly a stencil and an acidic etching paste, to engrave a vehicle's vehicle identification number (VIN) onto the windshield and windows. Most parts on a vehicle already have at least a partial VIN stamped onto them, and many auto parts buyers will not purchase parts that carry identification numbers ...
VIN on a Chinese moped VIN on a 1996 Porsche 993 GT2 VIN visible in the windshield VIN recorded on a Chinese vehicle licence. A vehicle identification number (VIN; also called a chassis number or frame number) is a unique code, including a serial number, used by the automotive industry to identify individual motor vehicles, towed vehicles, motorcycles, scooters and mopeds, as defined by the ...
The term "crystallographic etching" is synonymous with "anisotropic etching along crystal planes". However, for some non-crystal materials like glass, there are unconventional ways to etch in an anisotropic manner. [2] The authors employ multistream laminar flow that contains etching non-etching solutions to fabricate a glass groove.
For example, the first character always tells you what country manufactured the car. Although each VIN is unique to a specific vehicle, the positions of the codes stay the same across all VINs.
Lift-off is applied in cases where a direct etching of structural material would have undesirable effects on the layer below. Lift-off is a cheap alternative to etching in a research context, which permits a slower turn-around time. Finally, lifting off a material is an option if there is no access to an etching tool with the appropriate gases.
Simplified illustration of the process of fabrication of a CMOS inverter on p-type substrate in semiconductor microfabrication. Each etch step is detailed in the following image. The diagrams are not to scale, as in real devices, the gate, source, and drain contacts are not normally located in the same plane. Detail of an etch step.
Chemical milling or industrial etching is the subtractive manufacturing process of using baths of temperature-regulated etching chemicals to remove material to create an object with the desired shape. [1] [2] Other names for chemical etching include photo etching, chemical etching, photo chemical etching and photochemical machining. It is ...
In intaglio printing, the lines to be printed are cut into a metal (e.g. copper) plate by means either of a cutting tool called a burin, held in the hand – in which case the process is called engraving; or through the corrosive action of acid – in which case the process is known as etching. [6] [7] In etching, for example, the plate is ...
