A new line of phase-locked oscillators (PLO) deliver accurate and stable output frequencies with low phase noise and spurious performance, making them candidates for use in radar and other exciter or frequency generation applications. Typical applications include phase-locked loops, frequency synthesizers function generators and as a local oscillator source in receiver and transmitter stages. Pasternack’s […]
Do you really need soldermask and silkscreen for PCB design?
Duane Benson, Chief Technology Champion, Screaming Circuits As PCB assemblers, we’ve been asked the question,”Do I really need soldermask and silkscreen?” many times. And, we’ve been asked with good reasons. To us, soldermask protects exposed metal, reduce the chance of shorts and keeps solder where solder needs to be. Silkscreen removes ambiguity, ensuring that parts […]
