How to solder LV5083A?
Fireball:
Hi guys!
Please, any idea, how to properly solder LV5083A chip?
Many thanks for hints!
amyk:
Hot air gun and solder paste. Preheater recommended.
Ian.M:
... paste stencil recommended.
MegaVolt:
And then x-ray for control.

Thanks for hints. The best way seems to be paste+stencil. The problem is, that the stencil is not existent :(
I decided not to use my hotair rework station, but manual one.
As a preparation I covered chip outlets using shiny tip with a ball of SnPb solder + a lot of flux, then wicked out and cleaned with IPA.
The same I plan to do with the PCB, but without wicking out. Then IPA cleaning.
Finally manual hotair with the smallest flow available (I have very powerfull 1kW device) 400 °C, very small ammount of Amtech NC, 2-3 mins preheat (temperatire measuring all the time) and final reflow about 60 secs at 240 °C.
What do you think?
Thanks fo your opinions in advance!
