Retronix recently carried out
successful underfill removal from a cellphone pcb that had to have a chip
replaced, however the pcb was underefilled. Also the chip was under a can and
was densely populated
We removed the can, then the
damaged chip, then the underfill that was under the chip, and surrounding it.
After cleaning up the pads we
replaced the chip and tested the pcb. When it passed we replaced the underfill,
replaced the can and retested it to ensure the fix was successful
