Watch the vid carefully towards the end. You can see the chip being flipped into alignment by capillary action when the solder melts

Non pb solder flow temperatures are higher than pb solder. It wouldnt be uncommon to use a temperature of over 400 degrees for short periods.

The ambient temperature in workplace is vital. Work in too low a temperature and you will struggle to remove the smallest of devices, makes for a much easier life

….BUT… What is the music track in this vid?!?

times?

Times vary depends on chip size

mine just cools right away

Sounds like you need to get the ambient temperature up and maybe use a desk lamp to prewarm the board

i am going to try that
thank you very much
but what is the material you used in order to get the chip to stick,
stick while staying in contact with a conductive material
