-
已经从两个焊盘去除了电容。 当电容从板上拉出时，每个焊盘都已被加热。
-
要打开被焊料阻塞的孔，请用烙铁尖端加热焊盘。 用缝合针或缝针从另一侧推出熔融焊料。
-
当工具完全通过该孔时，通过加热焊盘的顶部，同时用工具来扩大孔。
-
沿着每个触点的长度滑动烙铁头，将焊料从部件上擦去。 通过海绵将烙铁头擦拭干净，清洁烙铁铁尖。
-
将触脚插入并穿过焊盘上的孔。
-
为了方便焊接，略微弯曲通过孔突出的触脚，使它们保持在适当的位置。
-
焊接连接：
-
将烙铁头放在焊盘上。
-
将足够的焊料熔化到焊盘上，以使电容器的触点引线牢固地固定到位。
-
一旦足够的焊料熔化到焊盘上，移走烙铁和焊料。
-
-
通过加热电路板的顶部的接头，同时用镊子拉出导线，将引线从焊盘上取下。
-
在从板的另一侧加热相同的垫片时，通过将一个钉子压靠在堵塞物上，通过焊盘打开孔。
-
清除所有孔后，用镊子插入引线的裸露端。
-
焊接每个连接：
-
将烙铁头放在焊盘上。
-
将足够的焊料熔化到焊盘上，使接触引线牢固地固定到位。
-
一旦足够的焊料熔化到焊盘上，则取下焊料和烙铁头。
-
-
要焊接接头，将吸锡线放在现有焊球的顶部，然后用烙铁将吸锡线向下压。
-
一旦焊料熔化并流入吸锡线，从接头上取下吸锡线。
-
对剩余的引线重复相同的步骤。
-
将一小块焊料熔化到每个焊盘上：
-
将烙铁头放在焊盘上。
-
熔化焊料，使其在焊盘顶部形成圆顶形状。
-
一旦足够的焊料熔化到焊盘上，请从焊盘上移走焊料和烙铁头。
-
-
要将新的引线焊接到电路板上，请将一根导线的裸露端放在相应焊盘上的焊珠上。
-
将烙铁头放在焊锡珠上，直至熔化。
-
将引线的暴露端滑入焊料中，直到其位于焊料的中心，然后取走烙铁。
-
以相同的方式继续其他连接，特别注意不要将两个焊盘焊接在一起。

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.
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!

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)..

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.
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.
Nice post describing PCB Repair soldering with images. It is quite easy to understand also.
This is for "Introduction" but didn't see how to comment there.
Says "newer generations" have soldered batteries but there's no reference as to when this was written so that's not very meaningful. Request clarification.
