As above, use a baking sheet too to separate the component from the pan.
As GTV1 said, you could do alot more damage keeping in mind that PC processors usually shut down for safety at around 90-100c, you are going to hit twice that in your oven.
Just performed a reflow on my Bluetooth module and lo and behold it has started working again!!
I have suffered poor connectivity since getting the car, a year now, and as previously stated probably some sort of dry joint/poor connection, as I used to be able to get it to connect by tapping on the panel to which the module is attached.
I have tried removing the boards and cleaning everything as previous posts have tried but did not help.
Anyway as the unit was defunct it was a case of what have I got to lose.
Did the reflow as suggested 200C in a non fan assisted oven for 10mins, up to now all ok.
I did suffer from the parasitic drain as some others have before and disconnected my Bluetooth module because of this and haven't had an issue since with the battery, even leaving it for 3 weeks in Februarys cold weather whilst I was away.
Good luck with finding out what causes this as I'm sure that there are loads of people out there who have units waiting for repair.
I will post if the drain issue resurfaces, but it is good to get the little phone icon back in the display.
