Stray capacitance in pcb
WebThe Embedded controller is fast, but not as fast as a computer, so it executes every instruction quickly. When the energy supply is on, the control register enables the quartz oscillator. During the initial few milliseconds, as the setup is underway, the stray capacitance starts charging up. WebUnique LUXMAN PCB layout. Dielectric effects, unwanted resistance and stray capacitance in printed circuit board patterns can all degrade the audio signal. LUXMAN suppresses these effects with generously thick 100 μm copper foil, gold-plated connections and peel coat removal of the solder mask. In addition, our gently curved wiring pattern ...
