vacuum coating:
  
           Vaccum coatings processes use a vacuum (sub atmospheric pressure) environment and an atomic or molecular condensable vapor source to deposit thin films and coatings. the vacuum environment is used not only to reduce gas particle density but also to limit gaseous contamination, establish partial pressures of inert an reactive gases, and control gas flow.

Breadboards:

Breadboards are the fastest way to build circuits, but until you get used to them, they can be confusing. its important to understand where the holes are connected and where they are not connected.
The pattern of holes varies from model to model; some breadboards have only one strip down each side, and others have multible side rows. The basic model, with many horizontal rows seperated by a central divider and one or two long side rows, called bus rows, is the type that we'll focus on.

Electro chemical grinding:


Electro chemical grinding (ECG) is a combination of ECM and the grinding process. The metal is removed both by anodic dissolution as in ECM and abrasion as by a grinding wheel.
In this process, both the grinding wheel and the work piece have to be conductors of electricity. The grinding wheels employed are in general metal (phosphor bronze) bonded diamond wheels or metal bonded alumina wheels in ECM, in electro chemical grinding also, the work piece is connected to the positive terminal and wheel to the negative terminal of power supply.
