How Do Material Qualities Differ for HSD Versus mmWave Circuits?
Growing use of millimeter-wave (mmWave) frequencies for applications such as automotive radars, Fifth Generation (5G) wireless networks, and satellite communications (satcom) mandates careful selection of printed-circuit-board (PCB) materials specially formulated to transmit signals at frequencies to 70 GHz and higher. At the same time, digital…
Isola Releases IS550H Material: Interview with Experts
Interview by Nolan Johnson Nolan Johnson speaks with Michael Gay of Isola and Chris Hunrath of Insulectro about the release of their new halogen-free, high-thermal reliability material, which they hope fills the gap in the market between epoxies and polyimides. Nolan Johnson:…
Check to select frequencies to calculate impedance. Check to highlight the copper layer of interest. Uncheck reference check box to designate a signal layer. By default, all layers are treated as a reference plane. 4. A ‘green’…
