TECHNOLOGIES FOR POWER TUNNEL ON CIRCUIT BOARD

To provide: a power tunnel on a circuit board which has a high cross-sectional area and can carry a larger amount of current than an equivalent-width trace, reducing the area on a circuit board required to carry that amount of current; a method of making the circuit board; and a system.SOLUTION: In...

Summary:To provide: a power tunnel on a circuit board which has a high cross-sectional area and can carry a larger amount of current than an equivalent-width trace, reducing the area on a circuit board required to carry that amount of current; a method of making the circuit board; and a system.SOLUTION: In a method of making a printed circuit board, a power tunnel 422 is created in a circuit board by drilling through non-conductive layers 404, 412, ... to a conductive trace 406 and the like and then filling the drilled hole with a conductor.SELECTED DRAWING: Figure 17 【課題】高い断面エリアを有し、それと幅が同等なトレースよりも多量の電流を搬送することができ、その量の電流を搬送するのに必要な回路基板上の面積が低減される回路基板上の電力トンネル、その回路基板を作る方法およびシステムを提供する。【解決手段】プリント回路基板を作成する方法は、非導電層４０４、４１２、・・・中から導電トレース４０６等へと削孔し、次いで、削孔された孔の中を導体で充填することにより、回路基板内に電力トンネル４２２を作る。【選択図】図１７
