My grandparents computer is an older iMac G5. When installing an Airport card in it last weekend I noticed that a number of the capacitors were domed, and some were leaking electrolyte, a sure sign of failing capacitors, possibly because of the capacitor plague<\/a>. After digging around through Digi-Key, Mouser, et al I found that the cheapest way to get a set of replacement caps is to order them from The Cap King<\/a>. He sells a set of the 25 needed caps for $16 shipped, and the set<\/a> arrived earlier this week<\/a>.<\/p>\n

After sorting the caps<\/a>, tearing down the iMac, and removing the logic board<\/a> I identified which caps needed to be replaced<\/a>, marked them by type<\/a>, then set about desoldering two of the most accessible ones. This is where I began to have problems.<\/p>\n

Normally I’m pretty decent at soldering, but getting these first two caps out was difficult. The first one left a lead sitting in the board, and the other three holes still contain solder. I presume its because of the number of layers in the board and the giant planes of copper near them, but I cannot seem to get enough heat on the board to melt the solder all the way through and wick it out.<\/p>\n

Here are two photos of where things currently stand: 1<\/a> · 2<\/a>. I think the next thing I’ll try is pre-heating the board with a hair dryer, then leaving the hot air flowing over it while attempting the desoldering. Hopefully that’ll help.<\/p>\n","protected":false},"excerpt":{"rendered":"
