Genny,
We use Kapton Tape. In some instances we will put multiple layers
depending on the rework required. Not only BGA's but on rework over
solder pots as well.

Subject: [TN] Shielding for BGA rework

Hello again,
Does anyone use any shielding for adjacent components and PCB material
when they are reworking a BGA, in order to minimize the heat seen by
those areas in close proximity?

If so, what do you use?  Is there a commercially available product, or
do you just make your own as needed (someone here said they had seen
foil and kapton tape used elsewhere).

Thanks much, as always.
Genny.
