As the world is becoming increasingly virtual and software is replacing hardware, electrical and electronics engineers are trying to ride the same bandwagon with their tool of choice, PCB (Printed ...

There comes a time in every maker’s career where solderless breadboards won’t do, perfboard becomes annoying, and deadbug is impossible. The solution is to manufacture a PCB, but there’s a learning ...

It is getting so easy to order a finished printed circuit board that it is tough to justify building your own. But sometimes you really need a board right now. Or maybe you need a lot of fast ...

在高速PCB设计中，BGA、QFN等高密度封装器件的breakout布线（又称neck-down区域）往往是信号完整性的薄弱环节。当走线从焊盘引出时，线宽骤变、参考平面不连续、空间受限等问题会引发显著的阻抗突变，导致信号反射、边沿畸变甚至误码率上升。如何在这一关键 ...

Analog circuit design guidelines. Digital circuit design guidelines. Differences in the guidelines between the two. Several products in the electronics industry require both analog and digital printed ...

Though often used as synonyms, Electromagnetic Compatibility (EMC) is really the controlling of radiated and conducted Electromagnetic Interference (EMI); and poor EMC is one of the main reasons for ...

Moore’s law, applied to data rates, has pushed PCB circuits so fast that the layout becomes part of the circuit. In designs such as DDR3 and PCIe, the fastest memory and high-speed serial performance ...
