I have never placed a bga chip before and need to know some o0f the basics of how to do it. I am really intrested in how the stencil will work with the soider and if there is a special soider that i need to use. I usually use a leaded soider from mancorp if anyone has any tips for me i would appericate it

I seemed to have learned that on the bga chip that the soider is the soider balls on the chip. If this is true how do you get the chip to not move on the board when being inspected bdfore you soider it. and even in the transport of the board to the oven.

Solder paste on the pads will keep part aligned. If you do not use paste, you will need to apply tacky flux. You should not run without one or the other.

if the BGA has leaded balls use leaded paste if the BGA has lead free balls use lead free paste and set your oven profile to match the paste
