  1. Comment souder et dessouder des connexions, Débutant: adım 1, 1 resimden 1.
    • Pour commencer, soudons un grand composant traversant fixé sur un circuit imprimé via des trous traversants.

    • Un condensateur a déjà été retiré des deux pastilles de soudure. Chaque pastille a été chauffée pendant que le condensateur était retiré de la carte.

    • Notez que les trous des pastilles de soudure sont complètement recouverts d'étain. Débouchons ces trous pour que les pattes du composant puissent passer à travers, cela en simplifiera grandement l'installation.

    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.

    Are we to assume that “ESD” stands for “ElectroStatic Discharge?” Keep in mind that newbies (like me) don’t commonly see or use these abbreviations.

    That is correct! I’ll adjust the introduction to clarify that.

    • Pour déboucher le trou bloqué par la soudure, chauffez la pastille de soudure avec la panne d'un fer à souder. Poussez la soudure en fusion de l'autre côté avec une agrafe ou une aiguille à coudre.

    • Dans notre cas, nous avons décidé d'utiliser un fil en acier plié à angle droit. La soudure au plomb ne colle pas à l'acier, donc presque n'importe quel objet mince en acier peut être utilisé.

    • Faire passer l'intégralité de l'outil à travers le trou peut nécessiter de chauffer la pastille de soudure plusieurs fois. En règle générale, chauffez la soudure juste assez pour qu'elle fonde, puis retirez la panne du fer de la pastille. Trop de chaleur endommage les composants électroniques.

    For god’s sake buy a cheap solder sucker. They are trivial to use. This is a tutorial after all. It’s certainly easier to use a solder sucker than to make a clean solder joint.

    Pro tip here - if you are having a hard time taking out solder, USE MORE SOLDER. Yes, it sounds counter-intuitive, but I’ve found that adding a dash of new solder to the troublesome blob you’re working on really helps get out stubborn old solder. Works even better with a solder sucker!

    i would use some flux and then some solder wick. flux makes like easy with soldering!

    Logixal - Yanıt

    Absolutely get some liquid flux involved here. Flux prevents the hot solder from oxidizing and keeps the liquid metal flowing - either into solder wick or a vacuum sucker.

    reccomended tempature?

    Travis Gann - Yanıt

    Usually around 300 - 350° C gets the work done.

    good god thank you. finally someone asked & answered. a tutorial for this kind of extremely difficult, heat sensitive work - yet no mention of a safe, recommended temperature.

    these tutorials are for beginners after all , aren’t they?

    • Lorsque l'outil a complètement traversé le trou, agrandissez le trou en chauffant le côté supérieur de la pastille de soudure pendant que vous appuyez sur l'outil.

    • Les deux trous de soudure devraient maintenant être suffisamment ouverts pour que vous puissiez y insérer les pattes de votre composant.

    Using a solder sucker will make it a lot safer to the board/copper traces than using a needle or paper clip to clear the hole.

    J. Goodenough - Yanıt

    Yes, please use a solder sucker, or even solder wick.

    If you don’t have some flux laying around, add a tiny bit of new solder if the old solder is being stubborn and not going away. Sounds odd adding more solder to remove solder, but it works!

    J. A. Gonzalez - Yanıt

    Yikes. This is a horrible step. It risks tearing the pad and the via, and it also stretches the FR4 which would create microfractures in the internal layers. Use a lead that the same size or smaller than the hole if you absolutely have to clear it like this. Jamming a scribe into the hole is no bueno!

    Sonar Tech - Yanıt

  4. Comment souder et dessouder des connexions: adım 4, 1 resimden 1.
    • Préparez votre composant pour la soudure en enlevant tout surplus de soudure des pattes. Les pattes doivent être suffisamment propres pour passer à travers les trous des pastilles de soudure.

    • Faites glisser la panne du fer à souder sur le long de chaque patte pour essuyer la soudure du composant. Nettoyez la panne du fer à souder en l'essuyant avec une éponge humide.

    • Trop de chaleur risque d’endommager le composant, n'appliquez pas le fer à souder sur le composant pendant de longues périodes.

    Don’t use a moist sponge if you can avoid it. Water from a moist sponge will get into your tip’s micro-fractures and oxidize it rapidly. I’ve lost many tips to moist sponges.

    Use a cheap solder scour pad instead. They are made of copper, which is soft and will scrub solder away without damaging your tips. If you can’t afford a proper scour pad, make one yourself. Go to the dollar store and buy a copper wire scrubber for like 50 cents. I use the dollar store scrubbers to replace old worn out scour pads.

    J. A. Gonzalez - Yanıt

    ADD LIQUID FLUX before doing this step. No mention of flux yet and we’re at Step 4? Maybe we need a guide for the guide!

    • Pour souder chaque connection :

    • Placez la panne du fer à souder contre la pastille de soudure.

    • Faites fondre juste assez de soudure sur la pastille de soudure pour que les pattes du condensateur soient fermement tenues en place.

    • Retirez la soudure et la panne du fer à souder de la connexion dès que suffisamment de soudure a fondu sur la pastille.

    Using a little electronic soldering paste on both the components leads and board traces will eliminate the need for excessive heat build up, there by making a sound electronic connection.

    J. Goodenough - Yanıt

    Not everyone has soldering paste handy unless they are going to do a lot of soldering.

    Mike Gross - Yanıt

    Solder joint on the left is not good. Solder should be shiny and be shaped like the Atari logo.

    Solder joint on the right is very good, they should all look like that.

    J. A. Gonzalez - Yanıt

    The lack of solder flux here is the reason these joints wouldn’t get anywhere close to being passed by QA. Add flux and try again.

    • Ensuite, nous allons passer à une soudure moyennement difficile. Dans notre cas, nous souderons des fils très fins et fragiles à un circuit imprimé avec de petites pastilles de soudure.

    • Les petits composants électroniques, y compris les fils, ne peuvent pas évacuer la chaleur aussi rapidement que les composants plus gros. Cela les rend très sensibles à la surchauffe. Assurez-vous de chauffer la connexion juste assez longtemps pour faire fondre la soudure.

    • Les fils ont été retirés des pastilles de soudure en chauffant la pastille de soudure sur la face supérieure de la carte, tout en tirant les fils à l'aide d'une pincette.

  8. Comment souder et dessouder des connexions: adım 8, 2 resimden 1. Comment souder et dessouder des connexions: adım 8, 2 resimden 2.
    • Il est courant que la soudure couvre certains des trous traversant les pastilles de soudure du circuit imprimé. L'ouverture de ces trous simplifie grandement la soudure.

    • Débouchez les pastilles de soudure en pressant une agrafe dépliée contre ce qui obstrue le trou tout en chauffant la même pastille de l'autre côté du circuit.

    • Un outil "troisième main" (ou un ami) peut être d'une grande aide lors de cette procédure.

    Again, if you force any metal object through these holes you increase the chance of damaging circuit board traces on both sides of the board.

    J. Goodenough - Yanıt

    Take a green or yellow injection needle. Make the solder hot and push the needle through the hole. Injection needles are made of stainless steel and are not liable to the solder.

    • Après avoir débouché tous les trous, insérez les extrémités des fils à l'aide d'une pincette.

    • Pour maintenir les fils en place, il peut être utile de plier d'abord les fils de la batterie pour leur donner leur leur forme finale, puis d'en insérer les extrémités dans les trous.

  10. Comment souder et dessouder des connexions: adım 10, 1 resimden 1.
    • Pour souder chaque connexion :

    • Posez la panne du fer à souder contre la pastille de soudure.

    • Faites fondre juste assez d'étain sur la pastille de soudure pour que les fils soient fermement maintenus en place.

    • Retirez la soudure et la panne du fer à souder de la connexion dès que suffisamment de soudure a fondu sur la pastille.

    Add liquid flux to each pad before inserting the wires.

    • Pour la dernière section, les fils de la batterie seront soudés à des pastilles de soudure montées en surface. Ces types de soudure sont plus difficiles à souder parce que le fil n' a pas de point d'ancrage solide (comme un trou traversant) pour le maintenir en place pendant qu'on soude.

    • Pour dessouder la soudure, placez une tresse à dessouder sur la bille de soudure existante et appuyez sur la mèche de soudure avec le fer à souder.

    • Une fois que la soudure fond et imbibe la tresse à dessouder, retirez la tresse de la soudure.

    • Répétez la même procédure pour les fils restants.

    • Lorsqu'une tresse à dessouder est saturée de soudure, il faut la couper et la jeter.

    • Nous vous recommandons de nettoyer la surface des pastilles de soudure avec un chiffon doux, une éponge ou une petite brosse en nylon (type brosse à dents) et un peu d'alcool à brûler.

    • Pour faire fondre un peu d'étain sur chaque pastille de soudure :

    • Placez la panne du fer à souder contre la pastille de soudure.

    • Faire fondre l'étain afin qu'il forme un dôme sur le dessus de la pastille.

    • Retirez l'étain et la panne du fer à souder de la pastille de soudure dès qu'une quantité suffisante d'étain a fondu sur la pastille.

    • La perle de soudure doit ressembler à un petit dôme ou à un hémisphère. Si elle est plate ou dentelée, il suffit de remettre le fer à souder sur la soudure pour la refondre, puis de retirer le fer à souder. Il se peut que vous ayez besoin de rajouter un peu d'étain si cela ne fonctionne pas.

    Better still, apply some flux and touch it with the soldering iron and it will then flow properly.

    • Pour souder les nouveaux fils à la carte, placez l'extrémité dénudée d'un fil sur la pastille de soudure correspondante.

    • Appuyez la panne du fer à souder sur le fil et la pastille de soudure jusqu'à ce qu'ils fondent.

    • Faites glisser l'extrémité à découvert du fil dans la soudure liquide jusqu'à ce qu'il soit au centre de la soudure, puis retirez le fer à souder.

    • Continuez avec les autres connexions de la même manière, en prenant soin de ne pas souder deux des pastilles ensemble.

This is a great guide with awesome clarifying pictures.

Thanks!

Martin - Yanıt

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.

GURUmicro - Yanıt

just be careful doing this lol, flying molten solder can and will burn you or other components.

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)..

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.

Clarkness - Yanıt

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.

C.Vos -

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.

Clarkness - Yanıt

Perfect Illustrations, Thank you.

semi bariche - Yanıt

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.

Allan Ryle - Yanıt

Very good guidance

allwin2abbas - Yanıt

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

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 was quite surprised that flux wasn’t mentioned anywhere in this guide - and the pictures are proof that none was used.

Sonar Tech -

Really great photographs with excellent descriptions.

I believe any soldering procedure should start with selecting the right wattage soldering iron and tip for the task. Common small wattage soldering irons commonly used to solder small electronics are 15 to 45 Watts.

Second is tinning a new soldering iron tip. Tinning means the first time the tip is heated you melt solder onto the tip until solder sticks to the tip. Even if a tip is factory tinned you’ll want to tin it yourself. Solder needs to stick to a tip to correctly aid in the transfer of heat from the iron to the component.

Another (cheap) way to clean solder off connections is to use a squeeze bulb with a silicone tip. The squeeze bulb creates a vacuum when it is squeezed and the vacuum sucks the melted solder up into the bulb.

Jim Fogle - Yanıt

“Appreciated” Marvellous photos /snaps also nicely & thoroughly explained. Bravo.

BBN - Yanıt

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.
