[QUOTE="pigoo3, post: 1620927, member: 56379"] Yes that was me Charlie.:) As you probably recall from the video...he was working with a removable video card from the iMac (which I think would be easier to deal with trying the butane torch method)...versus trying to do it on a logic board with a non-removable video card (possible damage to surrounding components). But even then...the video chip on the card was surrounded by the vram chips (and other electronic "odds & ends") that could get damaged with the flame. The dude in the video was also very careful to remind folks that the flame needed to be constantly moving (don't leave in one spot too long)...or stuff could get damaged. He was also doing things "free-hand". What I mean is...in many of the videos I've watched doing the "oven bake method". The oven is set to a specific temperature...and the logic board is "baked" for a specific amount of minutes. So this method is somewhat "scientific". The guy in the video was just "eye-balling" things (guessing at time & temp). Finally he was holding the video card in one hand (on top of the Altoids box)...and heating it with the butane torch in his other hand. One other thing many of the video's mention is...the video or logic board being baked needs to be kept as perfectly level as possible. Otherwise the melted solder will run/flow where you don't want it to..and then one big mess!!! So this guy was holding things in his hand...and had to be: - very careful to keep it level - at the same time heating with the torch - keep the torch moving - at the same time thinking about the total heating time & temp Thus something he was probably pretty good at (a bit of an art)...since he probably did it a lot of times (experience). But I bet that he destroyed some when he was first learning how to do it!;) - Nick [/QUOTE]
