A Ball Grid Array or BGA package is a form of surface mount technology, or SMT package that is being used increasingly for integrated circuits. The BGA offers many advantages and as a result it is being used increasingly in the manufacture of electronic circuits. The Ball Grid Array, BGA package was developed out of the need to have a more robust and convenient package for integrated circuits with large numbers of pins.
Brain Motor Areas. The areas of the brain that control both gross and fine motor skills include the cerebral cortex, basal ganglia, and cerebellum. The cerebral cortex controls the movements of the muscles. The basal ganglia control position and voluntary movement. The cerebellum monitors muscles during movement.
What are fine motor skills? Fine motor skills involve the use of the smaller muscle of the hands, such as when doing up buttons, opening lunch boxes or using pencils or scissors. Fine motor skill efficiency significantly influences the quality of the task outcome as well as the speed of task performance.
