10. Hey! My chip meets spec. It’s the OEM’s job to design it in right.

9. The speed of light is 670,616,629.4 miles per hours. That’s really really fast.

8. I never had that problem on my last project, and this revision is only 30% faster.

7. The via stubs doesn’t connect to anything. What harm can they do?

6. My PCB vendor specs means I won’t have a problem: “Loss tangent – pretty close to zero. Roughness – almost no roughness. Metal resistivity – are you kidding? Copper’s a real good conductor.”

5. Skin effect? Isn’t that something to do with Photoshop?

4. S-parameters? No thanks. Don’t you have an RLC SPICE model?

3. 10 picoseconds? Listen to me: 10 picoseconds to ten decimal places is 0.0000000000 seconds.

2. If it doesn’t work we can always step up to Rogers’ material.

And the number 1 reason NOT to care about signal integrity is:

1. We’re hoping lower speed products will make a come back!

TGIF. Have a good weekend!
