In this tutorial we are going to learn about WHAT IS PCB DESIGN TIPS ?

• Separate slit apertures in PCB layout, particularly in GND planes or near current paths.
• Areas of high impedance give rise to high EMI, so use wide tracks for power lines on the trace sides.
• Make signal tracks stripline & include GND plane & PWR plane whenever possible.
• Keep HF/RF tracks as short as possible & layout the High Frequency tracks first.
• On sensitive components & terminations, use guard ring & Ground fill wherever possible.
• In Pcb Design guard ring around trace layers reduces emission out of the board; also, connect to Ground only at a Main one point and make no other use of the guard ring.
• When you have separate power planes, keep them over a common Ground to reduce system noise andpower coupling.
• The power plane conductivity should be high, so avoid localized concentrations of via & through hole pads (surface mount is preferred mounting method).
• Track mitering (beveling of edges and corners) reduces field concentration.
• Generally make tracks run orthogonally between adjacent layers.
• Don’t loop tracks, even between layers, as this forms a receiving or radiating anten
• Floating conductor areas of pcb don’t leave, as they act as EMI radiators; if possible connect to GND plane (often, these sections are placed for thermal dissipation, so polarity shouldn’t be a consideration, but verify with component data sheet).
