integrated circuits are put into protective packages to allow easy handling and assembly onto printed circuit boards and to protect the devices from damage. a very large number of different types of package exist. some package types have standardized dimensions and tolerances, and are registered with trade industry associations such as jedec and pro electron.
the total equilibrium tanks are completely filled with distilled water and a small amount of ordinary salt, to assist the hollow balls in remaining suspended in the centre of the liquid. in a second version, the 50/50 tanks, only half the tank is filled with distilled water, with the result that the balls float half in and half out of the water.

ceramic balls are electrically insulating, which can prevent 'arcing' failures if current should be passed through the bearing. ceramic balls can also be effective in environments where lubrication may not be available such as in space applications . in some settings only a thin coating of ceramic is used over a metal ball bearing.
