Unsolder Technique for Through-Hole Jacks

[bgavin]

I'm looking for advice on how to properly de-solder a through-hole multi-pin jack from a board.

This is a "pod" type modular jack with two rows of three flat pins.
Mounting style is "through hole".

My question is about the right tool for solder removal, and a technique for cleanly removing the old jack.

I was able to remove the part with my Hakko 936 and a sucker bulb, but it was ugly work.
I'd like to know how to cleanly remove all the old solder without risking damage to the solder pads.

would ChipQuik work?

To clean solder pads & traces:
Flux (paste or liquid), solder wick, rubbing alcohol (70% some stores carry 91%)

To remove most components:
1) Always add flux and leaded solder when desoldering. Helps old solder and lead-free solder to melt.
2) If a component has a heatsink attached, remove it.
3) If it's on a large ground plane and you don't have a hot air rework station, preheat the board with a hair dryer or heatgun. Becareful, very careful if using a heatgun.

While board is warm, work quickly with disoldering tools to remove component.

That's called a 'teardrop' lead... I imagine wick would suffice here.

If you aren't worried about the jack itself you can cut it up until you're left with just the leads and then you can desolder those one at a time.

A vacuum-pump desoldering tool would be good too because you get heat and continuous suction at the same time.

Other option is a small solder pot, heat all the leads at once and just pull it out.

Re: Unsolder Technique for Through-Hole Jacks

if its a bad component with as many legs as that, it does present itself a problem. I noticed this problem when replacing laptop power jacks. Many pins, going down, hard to 'walk out' cause other pins were dry. The solution I came up with doesn't work in all cases..

destroy the f'n thing. Its bad, right? I used a pair of dykes to literally cut the jack in half, and (carefully) cut and pull pieces of it off till I could take a pair of pliers and pull each leg out individually /w your iron. Doesn't work in all cases, and you need to be careful. If you break off the top of one of those pins going into the motherboard, it can be a serious pain in the ass to get it out

Uh... what's wrong with desoldering braid aka solder wick? Pumps tend to be messy, as they always drop small bits and pieces of solder everywhere.
