I'll be fixing a lot of Xbox 360's soon. I am in the process of doing an Atari 2600 fix/mod; and it's cake. But the 360 is, for the most part, a crippled semi-modern computer; the tolerances on part selection is a lot tighter. No Nichicon VX's here (even though some 360's have them).
I've seen a few Xbox 360 questions on here, and they've all pretty much focused on the electrolytic capacitors and polymer capacitors. Those I'm replacing with UCC KY's/LXZ's, some Panny FMs, and some Nichicon Polys. But what of all the tiny little SMD ceramics?
My main question concerns temperature coefficients.
I know what it means, but does it make that much of a difference in this application? Is it location specific; can I use cheapo Y5Vs everywhere or use C0Gs closer to the processor and cheap out other places or...?
Should I just avoid Y5V and worse altogether?
Or does it care all that much as long as something is there (going by a comment I read earlier about a coupler capacitor falling off not mattering...)?
Oh, bonus question: Tantalum. Any opinion on using it to replace electrolytics on motherboards, and what should be done if doing so (less capacitance, what to look for, etc)?
