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.
Fine motor skills are the small movements that occur in the hands, wrists, and fingers. These small movements work in conjunction with the eyes. Fine motor skills involve the following: Dexterity. Eye-hand coordination. In-hand manipulation. Grasp and prehensile patterns. Bilateral coordination.
