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.
It also helps us to develop and formulate concepts and ideas which later are shown through drawing and writing. We learn to move and move to learn. Gross motor skills involve the large muscles of the body that enable such functions as maintaining balance, walking, climbing, jumping, pushing, pulling and ball skills.They are the building blocks for the development of fine motor skills.Gross motor skills begin to develop right from birth, and keep developing at a rapid pace right up until we are around the ages of 6 and 7.o and Discover  sequential Development of Gross Motors skills All children are different and the development of gross motor skills are influenced by a number of factors e.g. childâs sex, opportunities for experience, motivation or interest.
