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!

Content:
(00:00) Introduction
(01:37) PCB Layout step 1: Memory Layout
(02:38) PCB Layout step 2: CPU fanouts – Powers, Decoupling capacitors
(04:05) PCB Layout step 2: CPU fanouts – Precise resistors / capacitors, Series resistors / capacitors,
(05:25) PCB Layout step 2: CPU fanouts – Crystals, Series resistors / capacitors, Termination resistors,
(06:25) PCB Layout step 2: CPU fanouts – Pull UP/Down resitors, Bootstrap resistors
(07:56) PCB Layout step 3: Fanouts for other Difficult BGAs
(08:52) PCB Layout step 4: Route Big & Wide Buses (PCI, ISA, …), do all the fanouts in the way
(13:54) About using same topology for all signals from same bus / group
(18:42) Tip: At this stage, do not worry how the tracks look
(19:40) Tip: Always use wider power tracks
(20:58) Tip: At this stage, do not worry about small violations, fix big violations
(22:31) Bonus time – DDR2 & DDR3 layout difference
(30:21) PCB Layout step 5: Differential pair routing
(39:45) PCB Layout step 6: Connect Long Length Buses, then High pin number buses and
(41:23) PCB Layout step 7: Local connections – Power supplies, Small circuits, Connectors
(42:23) Tip: Pick up a corner and work systematically
(44:14) PCB Layout step 7: Local connections – Analog areas
(44:44) Bonus – Where to download DDR2 & DDR3 Layout examples
(45:39) PCB Layout step 7: Connect rest of unconnected signals (1 wire nets, LEDs, …)
(46:25) PCB Layout step 8 (or Step 0): Connect Power nets
(50:36) PCB Layout step 9: To clear DRC
(51:37) About Impedances
(57:36) Impedance calculation
(1:01:55) Stackup
(1:06:50) Summary
(1:08:22) End
