Soldering tips and tricks - Tip5 Don't try to solder a wire when flux from solder was evaporated 

it's okay, he's not a factory or something...

@@voltflake wtf do u mean ? U don't know English or what 🤣

​@@voltflakeexactly

Better safe than sorry...

he is pro with clean and cool work

I domt really think so i thin you should only put the fluxing agent on the circuit board

Thank you forfeedback!

Why?? I don't know the use of hole at all. Allowing wires to get through and be soldered?

@@memebruh2024 Yessss duhhhhh

@@memebruh2024yeah, but generally each hole has a purpose, otherwise i think it would just be a pad not a hole

​​​​​@@memebruh2024 greatest example of common failures are smd components that experience stress physically example smd micro USB charging port. You will see them lift from pcb alot in comparison to hybrid through hole micro USB ports and also those mini HDMI ports that are also smd and don't rely on through hole support. Through hole provides more strength and support than smd does for I/O ports

It's okay... It can be a "vias pad" for more heat dissipation on the joint

Honestly I'm a beginner with soldering, and even more with smd. I heard about flux but I don't what it is why this so useful. Can you explain?

​@@Eckmuhl29flux does multiple things ... cleans the weld surfaces from oxids and gunk and prevents further corosion when hot during process. Transfers heat better to welding surfaces/welded objects and helps against thermal shock by distributing heat to a bit more surrounding surface. It's corosive tho so it has to be removed clean after weld

@@contytub thanks!

Some people don't know this. So this video may be useful to them.

​@@Eckmuhl29 I learned soldering when I was about 10. I didn't know the existence of flux other than the inner rosin core of tin wire. I developed a superb technique of soldering and i was creating strong and shiny joints. I certainly had soldering grease, but i just used it for cleaning the iron tip. When I was around 30 and years after an EE degree, i was told to use solder flux, specially for reworking with SMD. I throught that it wouldn't do any difference as my technique was already close to perfect. But once I watched a resin drop hanging from a branch of a pine. I was so intrigued the I dissolved such drop into a little bit of isopropyl Alcohol. Then I applied such mixture to some SMD pads and tried soldering some TSOPs.... Holly Sh*t!!!

Thanks for feedback! 😊

You are welcome

Thanks!

😆👍

I thought I was alone 😅😅😅

Yes, you are right. Depends on what materials you have

solder wire with flux is NOT better quality, it is type of wire for NOVICE. Pro solder has NO flux!!

flux costs nothing. Colophonium - $5 per Kilo, isopropyl - $10 per Liter. For $15 you have Kilo of flux.. :)

звучит геморно:\

для чего???

Its either cheaper. Or it conducts more for its mass. Even though copper conducts more for cross section area. Maybe. Something like that. Or maybe aluminum is just more plentiful and easier to find or can be easier to obtain by recycling or something like that. Mass is especially important in hydro transmission lines and also in vehicles. Maybe aluminum also has better strength and corrosion resistance.

​@@andrebello4191it can't take the place of copper, peoples have been using copper from many decades and nothing happens till now but aluminium products doesn't last for more than 5 years

well spotted. it is huge problem. Aluminum is much worse in conductivity, it doesn't solder well too - and it destroys copper in direct contact due to different internal metal resistance.

Yes, of course. This is what I shown. When you put solder on iron tip, all flux will be evaporated and you will not be able to solder it and I marked this part of the video with a big red X which means it is wrong.

You did the same thing straight after though

if your soldering iron tip is pure CRAP, you can't do it. But if you KNOW how to keep it proper - it is possible and good!

Condition of the tip has nothing to do with it, prolonging heat applied to solder causes it to start to crystallise which causes a substandard joint. And it doesn't take too long for it to start happening.

@@mahootina52 it has everything to do with tip. Solder does not crystalize and doesn't go bad - what you mean is that it oxidates. Thats what flux is for, it defeats oxidation. You can heat any metal to its melting point, it won't go bad. Flux should not be exposed to heat for a long time, as it evaporates and burns. Didn't I say that its a problem of NOVICE solder with flux core? You heat it up and it burns flux - and because you don't pre-flux, joints get too low flux and get brittle. Don't use flux core and use pure core with dedicated pre-fluxing. Or just add dedicated pre-fluxing to flux-core.

Any flux will work better than no flux. I've actually stopped using the stuff in the syringe because it goes bad before i use it all.
