Adding copper fills

An area on the PCB that is covered with a thin copper layer is called copper fill. Copper fills are used to create a ground plane. A ground plane is an area on the PCB that is grounded by being connected to one or more ground pads. Pads that are should be connected to ground […]

Calculate the appropriate track width

In the last chapter, you learned how to customise the width of a track. We didn’t concern ourselves with figuring out the appropriate width for a track though, but only have to control the width. In this chapter, I will show you how to use Kicad’s built-in track width calculator to calculate (instead of guessing) […]

Section introduction

In this section, we will enhance the design of the nRF24 breakout by going through a second iteration. We will add a bypass capacitor to the design, increase the width of the power tracks, and add a ground copper plane. To add the capacitor, we will need to update the schematic diagram in Eeschema, and […]

Controlling the track width

In this chapter we will improve the electrical characteristics of the PCB by increasing the width of the Ground and Vcc tracks. As far the features of this PCB are concerned, I think what we have now is enough. We could stop here and send it to the manufacturer but in general there are two […]
