In this video, Tech Consultant Zach Peterson tackles some of the most common mistakes he's noticed on twolayer boards and why upgrading to a fourlayer board might just be the solution you need.

We've received tons of oneminute design reviews (link below), and while the feedback has been fantastic, Zach's noticed a recurring theme – the tendency to stick with twolayer boards. Now, there's nothing inherently wrong with that, but it can lead to some avoidable issues.

Join Zach as he explores common pitfalls in areas like signal integrity, impedance, crosstalk, and PCB layout. He shows you how these can be easily rectified by making the leap to a fourlayer board with internal ground.

From USB line routing to RF designs and power distribution challenges, Zach covers it all. Discover the benefits of having dedicated ground layers, preventing crosstalk, and improving overall signal quality. Plus, Zach addresses the importance of layertolayer shielding to minimize electromagnetic interference.
