Production of glass in modern times has not change much since it was discovered in ancient areas of persia and egypt - sand which consists of silica, soda ash and lime is heated to extreme temperatures, and then is allowed to cool down and be shaped into almost any form by either blowing or pouring in pre-designed molds. this extremely easy process can also be enriched with additives, which ...
Another reason for using sand casting is the minimal costs when compared to other manufacturing process, the amount of time required for production of the parts, and the number of parts required in a production cycle. sand casting allows for the production of one part at a time if necessary, with no limit to the number of parts to be produced.

The process to manufacture chips from a wafer starts with the layout and design phase. highly complex chips are made up of billions of integrated and connected transistors, enabling sophisticated circuits such as microcontrollers and crypto chips to be built on a semiconductor surface measuring just a few square millimeters in size.
As the manufacturing process for a given chip or production line is perfected, more and more of the chips will be good. the ratio of good to bad chips on a wafer is called the yield . yields well under 50 are common when a new chip starts production however, by the end of a given chips life, the yields are normally in the 90 range.
