On May 17 and 18, Sierra hosted a workshop on PCB Layout Design Engineering. Whether you attended the two-day training or not, check your knowledge on this subject!
Annular rings are one of the biggest concerns of PCB designers. You know that you may place your via right in the middle of the pad in the design files, but it just does not mean that you will 100 percent avoid tangencies, or even worse, breakouts. Let’s talk about annular rings, shall we?
Controlled impedance is not science fiction… Especially when you know how to calculate your controlled impedance traces. But, do you? Open our free Impedance Calculator – which will help you answer some of the following questions – and get ready to take the quiz!
Designing a flex printed circuit board requires a slightly different approach than rigid PCBs. While flex PCBs can provide major savings in manufacturing cost as well as reduced space consumption and lower weight compared with rigid, their design must be optimized for their materials and use cases.

After establishing what a PCB transmission line is and talking about signal speed and propagation delay, and the critical length, the controlled impedance, and the rise/fall time of a PCB transmission line, we discussed impedance discontinuity and signal reflection. Today, we are going to explain how to analyze a PCB transmission line using quantities, such as voltages and currents, and line parameters, such as resistance, inductance, capacitance, and conductance.
