HI-TESN - Today we will again do soldering work, but not like the one where I talked about the basics of soldering, but other, progressive, or rather similar work.

 [SOLDER FIVE!]
today we will start soldering work again, now
not like that one, where I talked about the basics of soldering, but
other, progressive, or rather similar works.               
                                                        
the work will be carried out with the Spectrum, of course, so
like this. Well, he said it.                                   
                                                        
how to change the microcircuit?  well maybe she doesn't

or your spec is broken and you think it’s the problem
no!  What’s so funny, suddenly you’ll hit the mark! well, in short
how to do it:                                         
                                                        
It is not possible to remove old microfuge by desoldering

I did.  she has a lot of legs and therefore heat it up right away
Anything to get her out of the way won't work. while heating
one, the other will cool down.                                   
                                                        
you can take a needle from a syringe of a suitable diameter and
grind off its sharp end with a file to make it
just a tube.  and then you put this mikruhi on your foot
tube and heat the kohtakthy pad of this foot.     
                                         
the tube fits into the hole in the board, wears shorter
the leg of the mikruhi, thereby separating it from the solder on the board.
when the needle falls into the board, then press it slightly
twist it so that when the solder hardens it will not

well, the needle might get stuck in the board. and you won’t get it.
whenyou will do this with all the legs of the dismantled
mikruhi, then it can be easily removed from the board. this is it
will only work on single-sided boards, well on which
current paths on one side.                           
                                                        
no, well, if you move the needle properly, then maybe
damn, you'll tear off all the contact pads and
half the tracks. here.    
                                         
there are no Spectrums on single-sided boards. therefore
Remove the microhull from the Spectrum board without breaking it (the board)
impossible.  so this is how you can break off the mikruha (not
breaking the board):                                         
                                                        
with high-quality nippers, bite all the legs of the mikruhi as
as close to her body as possible. wire cutters db not loosened,
those if you look at the light through them, then there is a gap (slit)
there shouldn’t be any between their halves (well, of course, when
they are compressed or how to say...)                      
                                                        
well, naturally, they are small, so that you can

This is the part of the cutters opposite the handles.              
                          
if the nippers are fig, then the legs are bitten until
I categorically refuse a victorious end. try again
times.  and if you don’t get it, then buy normal wire cutters
specifically for this purpose. that's what I mean, no nada
There is nothing to snack on with them except tiny legs. then and again
never spoiled.                                      
                                                        
well, I’m exaggerating this, it’s still a mess, no
rejoice!                                                
                                                        
Increasingly, the process of biting legs is often complicated by the fact that
There are others standing nearby and you can bend something for them at the same time or
break.                                                
                                                        
well, you took a bite and the body of the mikruhi fell off. and fell.
Well, I took it and broke it all. now drink all your feet
separately... well, now we should solder in a new one
mikruhu.  yes, here's the problem - the holes in the board are all occupied
solder, in short, I’ll put it simply - they don’t exist.                   
                                                        
no. n-e-e-e-e-e-e-e-e-t!!!                             
fuck off!                                   
                                                        
_how to make it: you can take a needle (which is used for sewing)
suitable thickness, place it at one end to
hole (in common parlance - a hole) and on the other side
heat it with a soldering iron.                                 
                                                        
the needle will fall in there and when the solder hardens, you can
take it out and a normal hole will remain. here's the needle
may get stuck (most likely it will) andnothing at all
you won't get anything good.                                   
                                                        
and finally - the needle can screw up and then finally it's crap
get it.  without rosin and additive. incredible, but
checked several times.                                 
                             
but estb cnocon is better - (I came up with) - for the same purpose
you can use fluoroplastic insulation from the wire
mgtf (well, who doesn’t know him!).  now here she is racing and
It is difficult to insert it into the hole in the board.  but not
servant.                                            
                                                        
then I finally came up with a better cnocon - a match! and not
a gentleman and not a servitor.  who screams - and don’t go into the hole
climbs?  that's right, you need to sharpen the end of it with something,
so that it is thin, then everything will be fine. you are nocteneeho
grind it and try it on the hole, it’s easier.            
                                                        
well, you cleaned the holes, well done. check now, no
Do adjacent holes close /tracks, if so
carefully open the thread with something sharp, a screwdriver for example.
                             
now take the mikruha and see if its legs are tinned.
very often - yes, and if not, then cheat yourself. if
If you want, you can shorten them slightly, but not
stop trying, a millimeter is enough.  this is necessary for
so that they don’t stick out from the board when you solder it
into her (?). whoever likes it, of course...                 
                                                        
then anoint your feet (hers, not yours) with gumboil and insert it into
fee.  check how she got up, if it’s possible
solder.  press it tightly with your finger on one side, and
on the other, start soldering the legs.  apply it carefully
tip (not your own, but a soldering iron!) to the first leg.             
                                                        
the solder should wrap around the leg evenly and throughout
circles.   hold the soldering iron for two seconds, then
do the same with the other legs.  well how
recipient?  Well done, train, that's all for today!
