PCL370HR RAILWAY Standard NFPA 130 BSS 7239 Approvals

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…

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’…

When multiple resins systems are used, a hybrid notification will appear. Checking the shield or mask check box will add surface finish and soldermask to the outer layers. Units in mils, mm and µm can be selected. The Zoom function will compress the stack up…
