De/Soldering

[DanF]

Did my first DC Jack repair today, didn't expect it to work but it worked perfectly well

However, as you may expect, it took a hell of a lot of time. Was just wondering about the kit I'm using:

... with the 9SC116-SB standard tip.

The de-soldering process took the most, as there was practically no soldering on this Compaq DC jack, the soldering wick didn't pick anything. The soldering took only a minute but had an issue (which I believe is due to lack of experience) that soldering was getting attracted to the soldering tip rather than to the DC jack points.

Another problem was the the DJ jack takes a 5.5*2.5 adapter while the original took a 4.8*1.7

Are you using any flux? The flux will allow the solder to "adhere" to the parts you want.. including the braid during removal.. I have found that those little pointed tips are pretty crappy because they simply do not have the thermal capacity to heat up large surface areas. The chisel or bull nose ends work much better for larger work.

Thanks for your reply

No flux. You're right about the surface area, in fact at times I had to cautiously use the side rather than the tip. Will look into getting the 9SC116-2D tip as shown in the link above.

I'm not going to elaborate on this but if you want to do DC jacks every day with little to no pain you got to get yourself a good quality desoldering wick, good quality liquid no-clean flux and BISMUTH solid solder (google chipquik for a brand name). You learn how to work that and no dc jack can stand in your way.

I have done THOUSANDS of DC jacks and haven't used hot air in at least a year or two.

I'm doing my second dc jack repair today and I regret using Radio shack soldering equipment.

I picked up desoldering braid and it doesn't do the job.

Would you guys recommend this?

Do you recommend a particular TIP for desoldering jacks?

There seems to be quite a large amount of different tips, as shown here:

I don't know about everyone else, but I use a SMD rework hot-air gun for Desoldering. Makes the job way easier!
But if you don't have the SMD rework yet (get it, its worth it), then I recommend a tip with a larger surface area, as mentioned above. That being said, one of the biggest things you need for desoldering jacks is a very hot iron. The iron you linked was 20-40w. In my experience, 40w is minimum you need for removal, 50w or higher preferred (be sure to turn it back down for soldering, 25-30w is good for most solders). Dell jacks seem to use higher temp solder, so they take longer to melt also.
I never figured out that solder wick stuff, its just a PITA for me, so I stick to a good old solder sucker. Had to buy a good one, after I killed 3 cheapies. $20 well spent, as I can suck up any solder that's melted pretty easily...
What sucks is that if you use 2 different tips for desolder/soldering, you have to wait for the iron to cool before you can switch. This is time consuming. So try to pick a tip your comfortable doing both with, and keep it well tinned at all times while desoldering.

Just got myself an Aoyue 968A+ It has a 70W iron.

Iron and Hot Air gun still in plastic on my desk. Can't wait to try it out. Just wanted to get some more tips for its soldering iron, since it only comes with one.

Will try to remove a DJ jack with the hot air gun later on this week.
