PRINTED CIRCUIT BOARD CAPABLE OF EASILY CHANGING THE DESIGN OF A BALL LAND MAP AND REDUCING COSTS AND TIME FOR DESIGNING NEW MAP

摘要

PURPOSE: A printed circuit board is provided to reduce time and costs for designing new ball land map by varying the design of the ball land map through a control bar.;CONSTITUTION: A printed circuit board(100) comprises a core layer(102), a support bar(118), and a control bar(116). A first circuit wiring and a second circuit wiring are formed in upper side and lower side of the core layer, respectively. The support bar has the cylindrical shape. The support bar is inserted into the penetration hole of the core layer. A first conductive pattern of the support bar is connected to the first circuit wiring. A control bar is rotatably inserted into the support bar. A second conductive pattern of the control bar is connected to the second circuit wiring.;COPYRIGHT KIPO 2010
