[QUOTE="pigoo3, post: 1919601, member: 56379"] Yes the DIY oven-bake method of reflowing a GPU is definitely not very precise...and is full of risk. The main thing is getting the time & temperature correct (hot enough to liquify the solder...but not too hot to damage anything)...and long enough time-wise to do the same. As said...also not going to get the best solder joints. Anyone that knows anything about soldering knows...for a good solder joint...you need to start with clean surfaces to be soldered...and need both solder & flux for a strong joint. With the DIY oven method...the solder is only being melted...then cooled. No actual cleaning or new flux being added. The joints that result will probably be very weak/brittle...and the joints may not even fully form like they would be when new. The other critical part is the board being "baked"...needs to be as perfectly level as possible...otherwise when the solder melts...the hot liquid solder will run in all sorts of directions. I've seen videos of how a professional piece of reflowing equipment operates...very very different & much more precise than the DIY method. Don't get me wrong...lots of folks out there claim they've been able to successfully reflow GPU's & logic boards via the over-bake method. What they don't tell you is how many boards they destroyed learning how to do it right...or what their success rate is/was. Definitely a learning-curve...and not a 100% success rate. Definitely not as simple as adding air to a flat automobile tire/tyre...and back on the road again!;) Nick [/QUOTE]
