NON-PCB意为无公害绝缘油，它可以用于电容器的绝缘纸，以前的绝缘纸层常采用PCB【polychlorinated biphenyls】，就是聚氯联苯，这是一种有毒的物质，所以现在普遍不采用了。就是NON PCB ，Non 是法语，意义就是没有，不。AFC意为自动频率控制。是英语automatic frequency control 的缩写。此处说明本产品通...

This is achieved by replacing a uniform victim trace on a PCB with a continuously varying-impedance trace that exhibits a lowpass filter frequency characteristic. A simplified design approach of the proposed trace impedance profile which is governed by a truncated fourier series is presented. The ...
虽然,我们可以借助CAM 350 进行DFF Audit自动检测出“acid traps”潜在问题,避免在PCB在制造产生时产生加工瓶颈,如果PCB板厂工艺人员检测到有酸角(acid trap)存在,他们将简单地贴一块铜到这个缝隙中,好吧,老wu觉得,很多板厂的工程人员他们其实并不懂layout的,他们只是从PCB工程加工的角度进行了修复酸角(acid trap)...

如果未盖油塞孔的via,我们在layout时将过孔打的过于靠近SMT器件的焊盘,将会造成SMT器件在过回流焊时,流动的焊锡通过该过孔流到PCB的另一面,造成SMT焊料不足而虚焊等问题。通常建议,via过孔的边缘距离 SMT 焊盘边缘距离在 25mil以上,并且via过孔做盖油处理。
