I had very short time to remove some Atmel (AT90SL2343T) chips from discarder NOKIA communication equipment boards using standard hot air gun. It was very high quality PCB boards so I made some experiments about self positioning of some SMD elements to solder pads. Main idea is, that good design board can help solder some bigger elements. In this video big transistor-like element (National semiconductors LM2937) moves to its landing place.
Sorry for bad video quality.
