Acer 5515 Power Jack Replacement.

[zylcho]

Greetings, ran into the jack straight from hell today. I had one heck of a problem getting the jack off the board. The 45 watt pencil wasn't cutting it so went to the mombo jumbo 150/230 iron and man it still wouldn't release. Has anyone else ran into a problem like this? Any guidance on this would be greatly appreciated.

First clean the contacts from old flux with isopropanol or something and add lead solder to them. This will lower the temperature needed for melting and transfers heat better.
Good amount of flux (viscous) and highest temperature (around 450) on the iron. Need also a good tip for good heat transfer. Hot air station would be handy too.
Remove broken pins/solder with a fine tweezer and desoldering wick or sucker.

Cutting it to pieces works.

Hot air allows removal without any flux or solder. I heat the pin on the solder side with SMD hot air until the Hakko 808 melts the solder quickly on contact. Then I direct the hot air at the pin on the component side, melt, suck. Before hot air a partial suck required new solder. With hot air the lower mass of solder means it heats up more easily. A few more sucks and it's gone. Once the air can pass through the hot air gun heats quickly making hole clearing easy.

Hot air provides all the heat. The gun provides instant melting temperature.

Your board is still easy. There are HP boards where the board behind the jack is so narrow that you'll break it off with any other technique. The heat warps what you don't break.

Job got done and didn't look pretty but functioned. Thanks for the responses.
