Dear Ron. Thanks for this valuable explanation, but what I missed in this video is the tin sucker where you can suck up excess tin. These devices can also be purchased at an electronics or hobby store. Another useful item is an anti-static bracelet. You put this bracelet on your wrist and the end often consists of a (crocdilla beak) which you then clamp to a metal frame and in this way let the static electricity flow away. This prevents static electricity that can destroy or damage your electronic component.
Tin sucker -- like you mean, desolder pump? I think I mentioned that... I find it not very effective compared to desoldering wick. You have to clean it regularly, also it degrades with time.
I bought a solder station with a good tip and temperature control which saved me a lot of troubles. Been practising for years with mistakes and bad tools.
Any alcohol used to cleaning PCBs *is* an organic solvent. Such alcohols are quite volatile and highly flammable. Alcohol such as 2-propanol (also known as isopropanol or isopropyl alcohol) is quite effect for removing rosin-based fluxes but can perform very, very poorly with synthetic fluxes. Some "no-clean" fluxes are exceedingly hard to remove. It isn't the fact that oxides are heat barriers that cause them to interfere with soldering, it is the fact that they form a film through which solder simply can't penetrate. Fully activated rosin flux can cope with minor oxidation. In the hundreds of thousands of solder joints I've made over the years, I have very rarely used added flux (beyond that in cored solder) except for tinning stranded wire. Fluxes not intended for electronic work should *_NEVER_* be used for stranded wire. Flux can wick up among the strands making it virtually impossible to remove and resulting in an endless corrosion cycle. Fluxes not intended for electronics work are a very bad choice for ANY electronics work. Fluxes containing fluorides are serious health hazards - and inappropriate for electronics. The order of soldering pins of a DIP are completely and totally irrelevant The actual semiconductor die in a DIP is "isolated" by the bonding wires between the die and the DIP leadframe. The die may be soldered to the leadframe and hence to (often) the most negative supply pin. Remember that most modern semiconductor devices are heated in their entirety to the melting point of lead-free solder during standard reflow soldering processes. If you aggressively wiggle a lead in a plated-through hole when the solder has not been properly removed you can damage the barrel plating. It is bad practice that can be disastrous in multi-layer PCBs. It is, however, better than yanking out a poorly desoldered pin which can take the whole barrel with it.
I think there's a long-term debate going on on whether vaseline could be used in place of rosin flux, but I would say "rather no than yes". Although vaseline has similar feel, it still has different properties, lesser ability to carry heat and dissolve oxides, etc.
Well-explained video! Not sure if any custom PCBs are required for any upcoming content? If there's a chance, would love to support free services and get involved! Thanks. (PCBWay-zoey)
thanks, that was exactly what it needed since i suck at soldering
good video, i did some errors myself but i quickly noticed it is not good practice and sometimes dangerous

This covered more than I expected, but all of it good advice and very useful. 👍
Wow. That was amazing ☺️. Thanks for your detailed explanation.😻
Thank you for such an insightful video, so many great tips!
Thanks for all these tips! Especially the first one!!! Basic but nobody speaks about it
Thanks for the tips, I am a newbie and Don't know much about soldering.
Bro I am our 3 year ago in work electric repriing shop in Pakistan but your tips are useful for beingner and thanks for make this video

excellent video. Well done

very nice tips
thanks
Thanks for information
Merci
Thank you comrade.
Thanks very mach its very helpful
Thank you so much
Great video. 1-23-25 TH
what chemical is used to clean board after soldering?
It's better to use alcohol. Always works.
can you use vaseline as flux?
I think there's a long-term debate going on on whether vaseline could be used in place of rosin flux, but I would say "rather no than yes". Although vaseline has similar feel, it still has different properties, lesser ability to carry heat and dissolve oxides, etc.
