How to properly desolder the connectors so as not to damage the vias?

Question

Do it yourself

The other day I was repairing a USB hub with a deformed connector. The board is not very strong, and while unsoldering the connector, I ripped it out along with the via sleeves!
It worked out, I wired it directly to the tracks (the customer initially agreed that only 2.0 would work on this port). But how can you make sure this doesn't happen?

Answer 1

It is necessary to remove the solder from the holes "solder suction" - then warm up the lead so that it is soldered from the wall - release it gradually removing the soldering iron, reducing the contact area with the tip - so that the lead temperature is not enough for re-soldering to the wall of the hole.
With USB connectors, it is difficult only to unsolder the screen, since it has a large dissipation area and it is not always possible to warm up normally.

Answer 2

uniform heating and desoldering pump or copper braid with rosin. that's the whole secret :)

Answer 3

You can drip ordinary lead solder to reduce the melting point. The advice is universal.
