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. Continue reading “5 Must-Knows for Your First Flex Design”
After establishing what a PCB transmission line is and talking about signal speed and propagation delay, last week, we discussed the critical length, the controlled impedance, and the rise/fall time of a PCB transmission line. 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.
After explaining the importance of the signal speed and propagation delay in a PCB transmission line, we are now going to talk about the transmission line effects, the critical length, the rise/fall time and when the length of an interconnection is to be considered as a controlled impedance transmission line.
During DesignCon 2018, we met Bill Hargin, “Director of Everything” at Z-Zero, an innovative PCB stack-up design company. Bill told us about Z-Zero’s stack-up tool and shared some precious tips for PCB designers.
