Sounds like quite a feat considering hair dryer wont produce more than 50-60'C and solder needs >180'C to even start thinking about melting. Hair dryer in Bunn

Sounds like quite a feat considering hair dryer wont produce more than 50-60'C and solder needs >180'C to even start thinking about melting.
Hair dryer in Bunnies case was used to heat up the GLUE between glass and screen.
- noonespecial 12y agoJust partially block the air intakes. It'll get hot fast. Just be careful it doesn't start to melt inside.
- rasz_pl 12y agono it wont, there is a thermal cutoff inside
- noonespecial 12y agoHmm. I've got one here I use for heat-shrink tuning I used masking tape on to lower airflow and boost temp. I'm not sure its hot enough to melt solder (probably not) but its great for heat-shrink. I suppose a YMMV is in order.
- rasz_pl 12y agoIf you remove thermal cutoff you will: a/ burn the heater b/ melt whole thing c/ burn your house a combination of those things.
- Intermernet 12y agoYou're almost certainly right, I've not had success with it myself, and I originally thought the same, but I've heard anecdotal evidence from others that it's worked for them, and there are a few mentions of it online, including a video at http://www.anandtech.com/show/6840/hardware-tricks-can-you-fix-a-failing-mobile-gpu-with-a-hair-dryer http://www.anandtech.com/show/6840/hardware-tricks-can-you-f... , but I've also found mentions that the likely cause of the hair dryer trick is old capacitors being temporarily "revived" by the heat (http://www.instructables.com/id/Fix-a-dead-power-supply-using-a-Hair-Dryer-Reflow/ http://www.instructables.com/id/Fix-a-dead-power-supply-usin...). It seems like something is being at least temporarily repaired by the heat, but it's probably not anything to do with solder.
