Hello everybody, on today's lesson we'll learn which solder tin you have to use, why use it or what kind there are
Let's get started
Welcome everyone, Edgar here once again, happy and full of energy, greeting you all
Today we'll be talking about the solder tin and flux
It's nothing complicated, it's just something that you should know about your supplies, so
We'll be working with this kind of wire, the soldering wire
basically a wire
We'll be also working with solder paste
with two kinds of solder paste
so, let's talk about this supply
What kind you should buy?
I use the Kester solder wire
this reel is not cheap, it's a good brand
I'm not telling you to buy this
The links of the tools and supplies that I use, you can find them on my page here below
I'm not telling you that you should buy this one, but when you buy
solder tin, you must check what are you buying
actually, the solder tin that we use, it's mistakenly called "solder tin"
because it is tin-lead alloy
so we'll see the difference between tin
and lead
these two are completely different materials
that come together to create the material we use to work
with the amount of tin and lead that we use
the most of electronic engineers uses
is between 60% TIN /40% LEAD
this one I have here is 63% tin/40% lead
if the tin doesn't have lead
it'll be more difficult to solder and desolder
if it doesn't have lead
so, the alloy 60/40 is the most used and the one we use the most
soldering without the alloy of lead is not very recommended because
the alloy will break faster, like in 2 years
and that's what we know as cold welding
it's called fusion when this melts
the solder paste I use, there're a lot of solder pastes
I'm really happy with the Mechanic brand
I've never had any problems with it
With Mechanic, we'll be using the 183°C one
what does this means? It will melt at 183°C
and this alloy is 63% tin/37% lead
the other solder paste we'll be using must be one that melts at 138°C
these are the 2 kinds of solder paste that we'll be using, so
to ensure uniform soldering of the tin or make the soldering easy, we have to use flux
The flux is the supply we'll be using along with solder tin for...
So, the flux is the supply we'll be using to
make uniform solder or for better results
This is when we have to be careful, I'll tell you why
Someone could say "I'll buy tin without lead because it is toxic" and etc...
What happens here is, the tin and lead do not evaporate
This does not evaporate, what evaporates is the flux
what you smell when working is the flux
So, what happens with the tin? It stays on your hands
on everything you touched it stays there, so
with the flux, you must be very careful when you decide which buy
because the flux is what you'll be inhaling, and that's what will go to your lungs
you'll see on different
on different products the acronym RoH
RoH is an European directive that has been running since 2003
it has been running since 2003 and it's aimed to reduce the use of hazardous substances
so, if you see the acronym RoH on something related to electronics, it means it that has been approved by that directive
What does it mean?
It means my flux is organic, lead free
So that's something you must be careful about when choosing flux
The flux that I use is ChipQuik brand
but this is not a cheap flux
I've been using a lot the Chipquik flux
is not harmful, it is organic, I use it a lot and it's very good, so
When you're trying to find which one to buy... I've only used 2 brands
Chipquik and Amtec, these two are the only ones that I've used
when you're buying flux, make sure you get the most transparent possible
that means it will be easier to evaporate and clean
Now, the cares you should take with the solder tin
you must have to use gloves, and once you finished you must wash your hands
because, the tin and lead stays here
if you eat a cookie or something, all the lead will go into your body, so
I don't want to make it too long
When buying solder tin, make sure it is 60% tin/40% lead alloy
That's the perfect alloy to work with
Alloys without lead are harder to work
harder to solder or desolder and it breaks faster
for easy soldering, you must use the flux
make sure your flux has the directive RoH
that reduces the use of hazardous substances for the body, so
I hope you've enjoyed this lesson, share it, leave a like
and tell to your friends that lil' Edgar is giving some cool lessons for everyone who just started on this job
make sure your girlfriend watch the videos, make sure your wife or your kids watch the videos
and let's learn together
Bye!
