简介

新一代的iPhone,iPod nano, iPod touch 将电池直接焊在了逻辑板上。老款的iPod和iPhone使用连接器将电池与逻辑板相连, 新一代的设计让更换电池工作更加困难。 本指南将解释不同难度级别的焊接,以及在电子产品上3种常见连接方法的焊接技术指导。

第一步: 初级 — 大孔组件,如圆柱形电容;

第七步:中级 — 小孔组件,如电池引线和电阻; 和

第十一步: 高级 — 小型表面贴装元件。

首先,我们用通孔焊盘焊接固定在电路板上的大元件。
  • 首先,我们用通孔焊盘焊接固定在电路板上的大元件。

  • 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。

  • 请注意那些孔是否完全被焊料完全覆盖。 打开这些孔 - 径直将电容从孔中推入就好 - 安装十分简单。

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.

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。
  • 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。

  • 在我们的例子中,我们决定使用向右的角度。 铅焊料不会粘在钢板上,所以在任何的薄的板上可以使用。

  • 将工具一直穿过孔可能需要加热板子几次。 根据经验,加热焊料足够使其熔化,然后从焊盘上取下焊接头。 过热会损坏电子元件。

添加评论

  • 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。

  • 这两个焊接孔现在应该足够大以插入组件的裸导线。

添加评论

  • 准备已经清除了多余焊料的元件。 触点应足够清洁以穿过焊盘孔。

  • 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。

  • 过热会损坏组件,因此不要长时间将烙铁与组件相接触。

添加评论

  • 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。

添加评论

  • 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。

添加评论

  • 接下来我们将介绍一个中等困难的焊接。 在我们的例子中,我们将焊接非常薄而精细的导线到电路板。

  • 包括电线在内的小型电子元件不像较大的组件那样能够快速散热。 这使得它们非常容易过热。 确保加热连接处融化焊料的时间恰到好处。

  • 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。

添加评论

  • 焊料通常是通过电路板上的焊盘掩盖一些孔。 打开这些孔大大简化了焊接。

  • 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。

  • 第三只手”工具(或朋友)可以在此过程中大大帮助。

添加评论

  • 清除所有孔后,用镊子插入引线的裸露端。

  • 为了将引线保持在正确位置,首先将电池引线弯曲成最终形状,然后将剥离的端部插入孔中。

添加评论

  • 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。

添加评论

  • 对于最后一部分,电池引线将焊接到表面贴装焊盘。 这些类型的接头难以焊接,因为引线在焊接过程中没有固定的锚定点(例如通孔)将其固定到位。

  • 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。

  • 当一段吸锡线被焊料充满后,应对其进行修整和丢弃。

添加评论

  • 我们建议您用软布或海绵蘸取少量的酒精清洁表面贴装焊盘。

  • 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。

添加评论

  • 焊珠应该看起来像一个小圆顶或半球。 如果是平坦的或锯齿状的,只需将烙铁放回焊料上,再重新熔化,然后将烙铁拉走。 如果不起作用,可能需要更多的焊锡。

添加评论

  • 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。

This is a great guide with awesome clarifying pictures.

Thanks!

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.

One more thing about having your solder iron on the pads for too long. If you get them too hot the pad will actually separate and lift up off the PC board, tearing the delicate copper trace, and the PC board will be useless.

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

allwin2abbas - 回复

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

What is the best diameter of solder to use on iPod Shuffle batteries? Lead-free? Please be very specific. Thanks much!

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.
