Changed temperature advice.

| Jan 6, 2018 at 23:05 | comment | added | Fredled | Heating at 350C or more will result in melting the part and the PCB. Never use more than 250C. | |

Added note about re-alignment.

| Jan 6, 2018 at 22:26 | comment | added | Spehro 'speff' Pefhany | Maybe worth pointing out that it will usually be very obvious when the part has gotten enough heat as it will self-align to the footprint. It should be pretty straightforward with a 2-layer board, but I think a multilayer board with internal planes might be worth borrowing time on a reflow oven for. | |
| Jan 6, 2018 at 22:17 | comment | added | user57037 | That is very hard to say. However, being able to solder parts like that is a useful skill. Just look at the money spent on extra parts as an investment in your skillset and training. If you do it 5 times, I believe you will become pretty good at it. Use flux, get magnifying glass or microscope if needed, have someone help you if you need a third hand, etc. Watch some videos on youtube. | |
| Jan 6, 2018 at 22:09 | comment | added | eeze | this might need to be a seperate question, but do you think that if i didnt solder the pad, but put a small heatsink on top, do you think that might work? | |
