Can anyone suggest a good underfill compound that is readily available for manual dispensing. I need to underfill a small BGA less that 12mm square.

Have had good results with Loctite 3536 and Hysol 4527.

The 3536 is easier to use and handle, and can be reworked if needed.

I have no relation to, nor receive any benefit from any above mentioned company.
