9、 Break-Out 破出是指所钻的孔已自配圆 (Pad) 范畴内破出形成断环情形; 即孔位与待钻孔的配圆 (Pad) 二者之间并未对准, 使得两个圆心并未落在一点上。当然钻孔及影像转移二者都有可能是对不准或破出的原因。但板子上好几千个孔,不可能每个都能对准,只要未发生 破出 ,而所形成的孔环其最窄处尚未...
The fixture contains spring-loaded probes that simultaneously contact each test point on the board, allowing for all nets to be tested simultaneously. These machines conduct their tests very quickly, but the fixtures are expensive and time-consuming to design, build, alter, and maintain. Flying ...
