link to videos on soldering, and today00:00:05
we will tell you how to solder so that it is00:00:06
beautiful and, most importantly, high-quality00:00:09
work. Quite often our viewers00:00:11
ask how to solder correctly00:00:13
because when they sing. the soldering they00:00:15
produce is very ugly, the solder does not00:00:18
spread well, and the most interesting thing is that if they00:00:20
solder to the child very often after00:00:22
they have separated there00:00:24
may be no electrical contact at all,00:00:25
so the module may not work00:00:27
correctly or not work at all or00:00:29
even be damaged in order to start00:00:31
soldering we need to decide what kind of00:00:33
work do we want to do00:00:35
based on this, choose a suitable00:00:37
soldering iron, a soldering iron can be roughly00:00:39
divided into two categories: when the tip00:00:41
has a protective coating, it has00:00:43
soldering irons that do not have a protective00:00:45
coating, these are fairly budget-friendly00:00:47
soldering irons, they are perfect for00:00:49
wiring a network cable or other00:00:51
large-sized work problem The problem is00:00:53
that the tip is made of copper, which upon00:00:56
contact with atmospheric oxygen from high00:00:58
temperatures quickly oxidizes and burns; the solder no00:01:00
longer fits normally on the00:01:03
tip and has to be cleaned again00:01:06
using a Perry sand file. After00:01:08
cleaning, the tip must be immediately and00:01:11
this will to some extent protect it from00:01:13
burning,00:01:14
but this will only slow down the process and not00:01:16
stop it, and of course, with such00:01:18
soldering irons it is impossible to properly00:01:20
perform soldering work on circuit00:01:22
boards because the soldering points are00:01:24
quite small in size00:01:26
and the soldering iron tip is usually very00:01:27
large, despite this, soldering irons with00:01:30
such a tip are still used due to the00:01:32
high heat capacity and power and, most00:01:35
importantly, the low price, the same type of tip is also00:01:37
made of copper00:01:39
but has a non-stick coating. The tip on00:01:41
such soldering irons can be of various00:01:43
shapes, both pointed and thicker. The00:01:46
same can be found both on00:01:48
professional soldering stations and00:01:50
on soldering irons simply, we recommend00:01:53
taking a closer look at this option; they are00:01:55
already most suitable for our00:01:57
tasks00:01:58
thanks to such a non-stick coating;00:02:00
the tip becomes quite durable.00:02:03
Now that we have sorted out the soldering00:02:04
equipment, it’s time to deal with00:02:06
flux and solder, which are also an00:02:09
integral part of the soldering process; we00:02:11
will not focus on all the00:02:13
options solders and there is quite a00:02:15
large variety of solder, essentially it is an00:02:17
alloy of metals, the most popular00:02:19
solder is pos-61 and post 63, this solder00:02:22
consists of tin and lead in the proportion of 6100:02:26
39 or 6300:02:29
37 this is the most popular solder which is00:02:32
most suitable for our tasks00:02:34
and we will use them further use and, of00:02:36
course, we won’t be able to understand without a plus,00:02:39
let’s figure out what00:02:41
flux is, essentially it’s a set of substances00:02:43
that allow you to fight the oxidation of00:02:45
metals and make the molten solder00:02:47
plastic and flowing, and before fluxes can be00:02:51
divided into two categories, this is a plus and00:02:53
definitely requires washing and00:02:54
unmarked flux on the wedge in order00:02:56
for the flux to effectively cope with00:02:58
its task,00:02:59
its composition often uses branches and00:03:02
only conductive substances; such advantages00:03:04
must be washed off, and if00:03:06
this is not done, then ours. soldering will quickly00:03:09
rust and become unusable, and in00:03:11
some cases, the residues of the pluses00:03:13
can leak and disrupt00:03:15
the performance of the device. Such pluses are00:03:17
usually more effective even if00:03:20
you solder heavily or merged elements, but00:03:23
washing such fluxes is too00:03:25
much trouble and it’s not always possible to wash00:03:27
the flux by for one reason or another, and here00:03:29
important advantages come to our aid,00:03:31
from their name we can judge00:03:34
that they do not have to be washed00:03:36
since they have a fairly neutral00:03:38
environment and are very convenient to use, but00:03:41
they are usually not as effective00:03:42
as fluxes that require cleaning, but00:03:44
quite enough for most jobs,00:03:46
so we will use this particular00:03:48
category of fluxes, and there is also rosin,00:03:51
this is one of the first categories of folk00:03:53
fluxes.00:03:55
Those who are friends with a Soviet-era soldering iron00:03:58
today can always find pebbles of rosin, and00:03:59
it is better not to use rosin either separately or00:04:01
in the composition of the solder itself and up to plus can00:04:04
be either separately in a jar so00:04:06
the composition of the solder is integrated,00:04:07
let's sum up the interim result in00:04:10
our design projects, a00:04:12
budget00:04:14
soldering iron with a non-stick tip of 20-40 watts is perfect; this00:04:17
power will be enough for small00:04:19
soldering points and the soldering iron will not00:04:22
overheat unnecessarily because it is overheated a00:04:24
soldering iron can damage the elements00:04:26
that we will solder and due to the00:04:28
rapid evaporation of the flux from the high00:04:30
temperature,00:04:31
its efficiency and quality of soldering00:04:33
will drop, but now that we have figured out00:04:35
what type of soldering iron we need, flux00:04:36
and solder, we can begin to00:04:40
analyze soldering methods, let’s say we00:04:42
need to solder a block into a poitou to00:04:44
do this, take solder with a00:04:47
flux without marks and a soldering iron with it, the mountain imam squeezed,00:04:49
bring the solder to the soldering points and00:04:51
heat it up with a soldering iron, this place00:04:54
is heated not with the tip, but with the00:04:55
side of the java, so heating do not00:04:58
retreat, it will be more effective, we supply the00:05:00
required amount of solder,00:05:02
now we align the pad, after which00:05:05
you can solder all the rest the legs00:05:07
can also be used for this task00:05:08
in front of the board; we first install the00:05:11
pads in the breadboard00:05:12
and then install the board on top.00:05:14
Now we can start soldering using this00:05:17
method. The pads will stand perfectly straight. But00:05:19
what if we need to solder a component with00:05:21
long leads?00:05:27
legs in different directions so that it is00:05:29
fixed then everything is exactly like00:05:31
from the block after soldering both00:05:34
legs we bite off the excess with side cutters the disadvantage of this00:05:37
method is that it remains sharp and the00:05:39
leads are sloppy let's consider the second00:05:41
method it is a little more complicated we insert the00:05:45
element and bite off the excess length of the00:05:46
leads you need to leave a couple of millimeters00:05:49
for soldering, then we take a little solder on the soldering iron00:05:52
and, holding the element with tweezers,00:05:54
we grab one leg; it00:05:56
won’t be possible to solder it properly00:05:59
because there is no flux, it evaporated the moment00:06:01
we took it when playing with the soldering iron, our00:06:03
goal is to fix the element so that it does not00:06:05
fall out,00:06:06
then we can put the board on as we00:06:09
did earlier I soldered the second leg00:06:10
by feeding flux directly to the00:06:13
soldering point. As you can see, when we feed00:06:15
solder with integrated flux00:06:16
directly to the soldering point under00:06:18
the soldering iron, it manages to complete its00:06:20
task before it evaporates from the hot00:06:22
soldering iron,00:06:23
after we return to 1 and warm you up with a00:06:25
small amount of solder, here we00:06:27
need Essentially, we don’t need solder and the flux that00:06:29
is inside the solder for a00:06:31
high-quality connection,00:06:32
so everything turned out very neatly, but00:06:34
what if we need to desolder the part, we00:06:36
can use a00:06:39
special device for removing00:06:41
solder, bring the spring together, warm up the00:06:44
contact pad, insert a00:06:46
suction and press the button this00:06:49
process may have to be repeated several times,00:06:51
but the result is a clean00:06:53
contact without solder; the most interesting thing in00:06:55
some cases is to pump out the solder by suction;00:06:57
we need to add00:06:59
fresh solder there so that it becomes more00:07:01
plastic due to the flux in it;00:07:03
but how to desolder the part00:07:05
if there is no such device? tweezers by00:07:07
dropping the element and we will00:07:10
warm up the legs one by one, gradually pulling out the00:07:12
part over time, it will give in. The main thing is00:07:15
not to pull too hard so as not to damage it and do00:07:18
not heat it for too long so as not to00:07:20
spoil the board00:07:21
if you confidently but quickly warm up and the00:07:23
junction, the leg will very easily00:07:25
come out of the hole using which method00:07:27
the contact remains filled with solder, keep this in mind00:07:29
by the way, if you want to00:07:31
practice in the pack, there are00:07:33
special construction kits on AliExpress,00:07:35
quite a large selection of boards,00:07:36
however, we want to say a few words about00:07:38
our own developments,00:07:40
they are suitable for both beginners and00:07:43
for those who already know how to solder and want to00:07:45
assemble something - Something interesting Our00:07:47
largest village set contains00:07:50
several circuits at once, and if you00:07:53
don’t have the necessary tools, you can00:07:55
choose a configuration with a full set and00:07:57
in addition to the designer itself, you00:07:58
will get all the necessary tools00:08:00
for work. By the way, our kits00:08:02
even have solder, everything for00:08:04
soldering was pleasant and brought00:08:07
pleasure, now let's talk about00:08:09
soldering the wires, first of all, the wire00:08:11
will need to be00:08:12
covered with solder, remove the insulation,00:08:15
be sure to twist the wire strands,00:08:17
if this is not done, it will be a matrix and00:08:20
as a result, a couple of seconds saved00:08:22
on twisting will turn out to be a bad solder, and00:08:24
so we twist the wire, apply the solder with00:08:27
flux and while heating, covering the wire00:08:30
on all sides,00:08:32
do not forget that soldering is done with00:08:34
the side of the tip, and now, for00:08:36
example, we took solder without flux, we see00:08:39
that it is impossible to tin the wire00:08:40
because plus a very00:08:42
important component in soldering, it helps us00:08:44
fight oxides and makes the solder00:08:47
plastic if you need to solder the wire into00:08:49
the holes, we proceed in the same way as00:08:51
we soldered the elements,00:08:53
bite off the excess and solder it, but what00:08:57
if the wire needs to be soldered to an element00:08:58
or soldered two elements to each other,00:09:01
here the basic rule is to solder00:09:03
so that there is the largest00:09:05
contact area, that is, you need to solder the00:09:07
terminals are parallel, they are perpendicular; we00:09:09
also do not recommend twisting the wires00:09:11
around the terminals; it will be very difficult;00:09:13
there will be no need for them; let's try to00:09:16
solder two wires together; here it is better to twist00:09:18
them at the preparation stage and be00:09:21
amazed together; if the wires are00:09:23
thick, it is better to use a custom00:09:25
flux, preferably one that does not require cleaning00:09:27
this way the soldering will be better and00:09:29
neater, but you can solder in parallel00:09:31
exactly as we showed with the pins of the part.00:09:34
Now let's try to solder the00:09:36
SMD components. Apply solder to the first00:09:39
pad and place the element on top,00:09:41
heating the soldering area.00:09:44
Now the element is fixed in the right00:09:47
place and you can solder all the other00:09:49
contacts00:09:51
using the same. principle,00:09:54
microcircuits with a large number of pins are soldered,00:10:01
well, here are the basic rules of soldering00:10:03
that will help you quickly start to do high-00:10:05
quality soldering, over time, your soldering00:10:08
will reach automaticity when you find00:10:10
your hand, but for now, don’t save time on00:10:12
the nuances, only by following all the rules that we have00:10:14
told about your soldering it will be neat and00:10:17
reliable, don’t forget about the00:10:18
soldering kits that will help you improve your skills,00:10:21
but that’s all for now00:10:25
