在这个步骤中使用的工具：Tack Flux SMD291 no clean 5cc ROHS$13.99
-
在焊点上涂抹一层助焊剂。
-
将吸锡线的干净部分放置在焊点的顶部。
-
将烙铁头用力压在灯芯上 2-3 秒。您要将灯芯加热到足够的温度，以便熔化其下方的焊料。
-
当焊料浸透芯线时，滑动芯线，使新的部分接触接头。当芯线的颜色从铜色变为银色时，您就知道它已经浸透了。
-
一旦大部分焊料浸透到灯芯中，就将灯芯和焊嘴一起从接头处提起。

在这个步骤中使用的工具：Polyimide Tape$9.99
-
将组件固定到位并焊接角引线以将其固定到位。
-
或者，您可以使用 聚酰亚胺胶带 将组件固定到电路板上，然后焊接角引线。

TIP: Another method which works well for clearing solder from holes (especially on repairs like AC Jacks on laptops) is to use compressed air to clear melted solder from holes. A quick blast with a duster can works well (I have even used a drink straw in a pinch and blown out with a blast of air from mouth). Heat the solder until it liquefies, put the duster straw right above the solder and quickly hit the melted solder with an air blast to instantly clear the hole of solder. This works well on very small holes as melted solder does not always push out cleanly with metal tools. You have to be quick with the air blast because the solder re-hardens rapidly.
just be careful doing this lol, flying molten solder can and will burn you or other components.

Flying solder might also get into places you don't want it. Making shorts and other unwanted connections of which you don't know where they are, so it can give you a very hard time finding them.
This is not IPC standards but for the ghetto approach, it will get the job done. I solder in manufacture settings, run my own shop. This is wrong to a degree but will do. If ifixit would like tips from ILLFIXIT then your more then welcome!

yeaaaa….. i was going to say something along these lines lol. itll get the job done but its by no means the right \ best way to do the job.

A very good guide to soldering.
I have never soldered anything (I'm a girl you see), but your clear and detailed guidance inspired me to give it a go.
I was well prepared in advance-it could be difficult-and that helped a lot.
I have now got a new battery soldered into my Palm TX and I'm as happy as Larry (or Lorraine in this case)..

Go Gurl! I'm a gurl, too. I worked in my dad's machine shop for 13+ years. I hit the ground running. Programmed, set up, and fixtured, retro-fitted CNC Mills, using SurfCam and G Code programming. We used Master Cam for the wire EDM. My fave was running a standard lathe. I guess I enjoy cylindrical objects. We held tolerances of .005+/- .001, all the way down to .0003+/-.0002. That…is very microscopic. lol
…add to that, Public Relations, Inventory, Inspector, Fixing Crashed tools, Shipping, Document Control, and so on. All I know is, if it needs to be done, it can be done, if your sharp. And, sometimes we gurls, have a different “feel” for delicate or fine work, as compared to some of the guys. There is nothing we cannot do, as well as anyone else, if we want to, and are willing to learn, and practice. I'm ready to try a little delicate connecting, myself.

Using a solder wick braid is a good thing to do every time you are trying to remove solder from the thru-hole and pad. This is because after you use the solder wick you have a clean hole and a clean pad with just a slight film of solder on it and you have a nice open workspace without any old solder in there. Old solder doesn't have solder flux anymore -it's burned off-and won't "flow" around the component or wire leads and leaves an icy-looking "cold" solder joint, a dull grey glob of solder that is weak and doesn't conduct electricity very well. By wicking it off, the new solder, which does have solder flux, will be shiny, smooth, quite strong and conductive. I've been soldering since the early 70's and solder wick is a good friend if you use it right. No need for staples or picks, either.
Also, to help the solder wick pickup the solder faster and to help clean the solder pad at the same time, put just a little flux on the wick before applying the iron to the wick, then wipe the area clean with some alcohol, works great.

Perfect Illustrations, Thank you.
I found this to be a clear and easy tutorial on how to solder to remove and install small electrical components. Excellent for beginners and useful for experts in teaching situations.

Very good guidance
another tip is if you do not have a soldering station and your iron gets too hot just unplug it and continue and never ever dunk your soldering iron in flux if it is excessively hot because it will take the conductive coating off the tip of your soldering iron. also dont dip touch the tip of your iron (while its off) because the oils from your hand can burn through the tip like the flux.
ps: this is from my personal experience and its just some things to look out for
Nice job!
Well done,,,,
This is a good job thanks.
Sooo just bought a soldering iron, never used one before in my life, re attaching wires to a little motherboard for a light switch and dimmer, this page literally just taught me exactly what i needed to know and success the first try! Thank so much! finally someone knows they’re stuff instead of me having to go through 30 different pages of nothing on google lol respect dude! keep it up!
Great guide! It also helps to use a bit of flux on the points to aid with adhesion of new solder to the contact points, and to help with heat transfer from the solder tip onto the solder pad.
I need to solder my wifi it came loose on my insignia tablet. All i need to know is where its located on mother board. Please guide me
Plug in the soldering iron. Wait for it to heat up… test by tapping solder on to the soldering iron tip. Having ‘tinned’ the soldering tip, apply the tip to the component leg and PCB. If the component leg is comparatively ‘thick’, apply more heat to the leg than the PCB. Tap the solder jointly on the component leg and the iron tip. If the component leg is at the right temperature, the solder will flow and make a sound electrical connection. If the component leg is not at the right temperature, the solder will melt on the iron tip and ‘drip’ onto the component not making a good connection.
I’d never do any soldering without a solder sucker e.g. https://www.amazon.co.uk/Draper-23553-De... but be careful when using it on delicate PCBs as the suck can lift circuit tracks where too much heat has been applied.
I’m a little late with my comments but just had to brag about my younger days with Heathkits and other companies! I learned how to solder the hard way (without any instructions) and put together a B/W TV, a color TV, an AM/FM receiver and various other little projects. I understand Heathkit is coming back and encourage you younger people to enjoy the hobby of putting together their kits after doing these soldering lessons.

Absolutely. I’ve worked alongside women in the US Navy. Most of them are very competent, excellent technicians. Like guys, though, you have your whiners and slackers. We are all the same.
Some information in the top title area was misleading, as the iPod isn’t sold anymore (except for the touch with a soldered battery) and the iPhone has had a socketed battery since 2008. I fixed it in the latest unverified version.
and where/how do we post future questions ?
practice on eWaste first
We refreshed the soldering guide!

Great presentation. Very helpful for a newbie like me. One comment, in Step 10 you say concave and I think you meant convex. A concave tent would hold water if it rains.
Thank you @miha821! You may actually change the respective section yourself!
