Date: Mon, 25 Mar 2002 20:40:44 +1100 Another tip from someone who has burnt more than his fair share of silicon ..... The easiest way to remove an IC from a board (assuming you don't want it anymore), is to just cut it off with a scalpel, or X-acto knife. Start at any side, where the legs begin, putting firm (but not _hard_) pressure until there is a little 'tick', and then move the knife down one or two pins and continue. At the end of all this, you can just lift the main substrate of the IC package off the board, and remove the legs that are left with a soldering iron. Clean up the pads with some solder wick (and maybe some IC board cleaning fluid if your really anal like me ;), and your ready to put your new chip on the board. Just be careful not to push too hard on the knife, as you can run the risk of cutting tracks under the IC legs. I've tried other ways (would you believe a paint striper hot air gun?), and this is the one that keeps the board in the best condition. Just trying to help out where I can ......

You can then swap CPU boards with him. His CPU board works perfectly, it's only the serial port that is dead. > * Linus broke his Jukebox when he disassembled his box and > use a little excessive force when he put it back again. Apparently some > circuits burned. Oh, man, that smell is something I won't forget... One of those small screws penetrated the isolation of the red power cable from the batteries. Lots of smoke from underneath the display... An IRF7416 was killed. I will replace it later this week. I hope that was the only component that died... So the GDB stub might be delayed a few more days. It is actually working, but I have a few more things to do before I release it. Stay tuned. /Linus Received on 2002-03-25 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
