Can someone explain me what reflowing means please ?

And what is a BGA ?

Thx in advance ( searched the help for 30 minutes and didn't find these answers )

Hi,

Please look at the pictures below, the image of the RAM has BGA components, (Ball Grid Array) which means the solder is arranged in small balls on the underside of the chip.

reflowing means heating the chip, with hot air, to the point that the solder melts and "Re-Flows", this helps to fix any dry joints caused during manufacture.

Nice information, its always good to know new things.

Hello,
The Reflowing means probably not i fix red rings...
