Graham Sutherland / Polynomialthread in which I talk about why the "wrap your games console in a towel" or "reflow the bga" thing works to fix some consoles, and it's nothing to do with solder balls.

@[email protected] right. there are three main types of capacitors used in consumer electronics: aluminium electrolytics (and their fancy polymer cousins), solid polymer (tantalum), and ceramic (more specifically multi-layer ceramic, or MLCC). the aluminium electrolytics are the bigbois, lots of capacitance. good for bulk energy storage. bad at higher frequency stuff. the fancy alupoly ones are for higher ripple currents. tantalum are a middle ground. low voltage, high capacitance density.
