Fabio,

To open the thru-plated holes after you have used solder wick, heat the solder pads and push out the remaining solder with a wooden toothpick or a stainless steel needle.

Hi guys,
  I'm having some tough time installing the K3AUDPROTMDKT assembly on
the main board of my K3.
As for every upgrade, I am following the instructions. I removed the two
old electrolytic caps in a few seconds, it was easy and quick.

But installing the new tiny board, as easy as it seems, is just a
different matter. I was able to remove almost all of the remaining
solder, but the pass-thru holes just remain closed with some solder. I
tried with some solder wick but to no avail.
In addition, the pass-thru holes are so small that I don't have any tool
that I can use to try to open those holes while heating the board with
my soldering iron.
I tried to align the 4 legs of the assembly but -of course- pushing them
through the holes is not easy, as they bend as soon as I apply a minimum
force.
