How to Clean PCBs After Surface Mount Soldering?

Proper PCB cleaning removes flux residues, prevents corrosion & ensures reliability using solvent, ultrasonic, or vapor methods. Storage in dry environments maintains performance.
How to Reduce Harmonic Distortion in PCB Design?

PCB harmonic distortion stems from nonlinear current paths & ground issues. Fix with λ/8 capacitor placement, star grounding & GaN FETs to achieve 72dBc suppression.
