Fritzing
Fritzing. Etching is a subtractive method used for the production of printed circuit boards: acid is used to remove unwanted copper from a prefabricated laminate. This is done by applying a temporary mask that protects parts of the laminate from the acid and leaves the desired copper layer untouched. You can etch a PCB by yourself, in a lab

Copper T: Benefits, Side
Removal of Copper T is a simple and painless process. The removal must be performed by a healthcare specialist only. The removal procedure is performed by the physician who gently grasps the string with forceps and pulls the Copper T out of the vagina. The shape of the device is in a "T" shape that folds easily on pulling the string.

Advanced Process Possibilities in Friction Crush Welding
Oct 11, 2017Joining sheet metal can be problematic using traditional friction welding techniques. Friction crush welding (FCW) offers a high speed process which requires a simple edge preparation and can be applied to outofplane geometries. In this work, an implementation of FCW was employed using an additional wire to weld sheets of EN AW5754 H22, DC01, and
