Hello Fabio,
I think it had more to do with the sucker than me as it is quite hot so the solder melts quickly so it sucks up easy and out of the hole around the pin too. On wiggling the cap while heating the large pin I would just wiggle around lightly and when the solder melted it would move easy and so I would know it was loose melted.
Have inspected all the pads and holes with my head band magnifier and all looks good will verify with a dmm need to get a new battery as it is dead when I went to use it.
The 464 only uses the one cap at 1713 where as the 466 uses two my 464 only has one also.
On the three inside caps from the edge 1751. 1761, 1723 all the three holes in a row have the outer pads all connected to the ground trace so no need to jumper wire to the outer stand off pad as there is no trace on them and the same on 1721. On 1722 the single outer pad is not used so no wire there and 1781 the large hole pad not used either so no wire either 1722 is the one needing a wire as it has to have the single outer pad the - connection to the large hole on the inner row as it is the only ground pin used on that cap so small wire in BIG hole is prob to fill up maybe.
