Advanced PCB Layout (Video) – Lesson 8 of Schematic & PCB Design Course

Lesson 8 from the Schematic & PCB Design Course which I have created for you. Enjoy!

PCB Layout Tips & Tricks, DDR2 / DDR3 Memory layout, Differential pair routing, Wide bus routing (PCI, ISA, ... ), Impedance calculation, Stackup design, CPU Fanouts and more. Software used for demonstration: Altium Designer.
Chapters:
  • 00:00Introduction
  • 01:37PCB Layout step 1: Memory Layout
  • 02:38PCB Layout step 2: CPU fanouts – Powers, Decoupling capacitors
  • 04:05PCB Layout step 2: CPU fanouts – Precise resistors / capacitors, Series resistors / capacitors,
  • 05:25PCB Layout step 2: CPU fanouts – Crystals, Series resistors / capacitors, Termination resistors,
  • 06:25PCB Layout step 2: CPU fanouts – Pull UP/Down resitors, Bootstrap resistors
  • 07:56PCB Layout step 3: Fanouts for other Difficult BGAs
  • 08:52PCB Layout step 4: Route Big & Wide Buses (PCI, ISA, …), do all the fanouts in the way
  • 13:54About using same topology for all signals from same bus / group
  • 18:42Tip: At this stage, do not worry how the tracks look
  • 19:40Tip: Always use wider power tracks
  • 20:58Tip: At this stage, do not worry about small violations, fix big violations
