There is no shame in liquid solder flux.
Think of it as liquid GOLD.

About $6 a bottle, which will probably go bad before you use it up.

Now that is an interesting bridge rectifier.


Here a raspberry replacing a big chip:
 http://panteltje.com/panteltje/raspberry_pi_FDS132_matrix_display_driver/index.html
That thing has been working all day now since Dec 2013 without a glitch.
 http://panteltje.com/pub/matrix_display_zoom_IMG_6609.JPG
Nothing to worry about.

Even older, 1985 or so, still works:

>As you can see, the "world's worst" tag was no exaggeration!

Na, it is OK.


I sort of like soldering, but only 60/40, maybe it is the lead ...

:-)
 http://panteltje.com/pub/z80/graphics_card_top.jpg
 http://panteltje.com/pub/z80/graphics_card_bottom.jpg
have many boards like that....

Scroll down can you find the SMDs on the board?
 http://panteltje.com/panteltje/raspberry_pi_dvb-s_transmitter/
that is some Giggle Hz stuff too.
It is still working, in fact added some stuff.

Soldering is simple.

You need a good temperature controlled soldering iron,
some solder wick, some 60/40, and there you go.
I count to 14 at 320 C for it to flow ... around pins.

:-)

60/40 is for plumbing.

  The electronics industry settled on and proved to be the best 63/37 and 
for decades it was.  This RoHS shit is the worst thing the world ever did.
  Metallic form lead is not dangerous to the environment.

  If it were, there would be huge lead levels around all the damned police 
shooting ranges in the nation.  There is not.

The standard is for the tin content to be first and then the lead.  

The 60/40 is most common for electronic solder, but 63/37 is slightly 
better.

The plumbing is often 50/50, or was before the RoHS and lead free stuff 
started.  

I do agree the solders other than the tin/lead is very bad and hard to 
work with.  As I just do it for a hobby and in the US, anything I do is 
with the tin/lead.  If the area of a board I am working on has the RoHS 
type solder on it, I remove it from the part I am working on.

It is going to be interisting to see if the devices have the 'tin 
whisker'  problem that high tin no lead content solder can have in a few 
years.

Eh. This was the soldering job in a commercially-sold SMPS bench power 
supply from an Amazon.com reseller, IIRC, this was how it looked when it 
left the mfgr, I took this photo immediately after opening the enclosure 
and pulling the PCB (it had stopped working! can you believe it)

This is pretty bad. The box doesn't work.

Haha, I actually saw a small pile of those on the shelf at the local 
(well, only) brick and mortar components retailer in the Boston area, on 
sale for $8 each in kit form.

I think I'll pick one up next time I don't think I've ever owned a 
capacitor substitution box before, or really needed one (it's easy to 
substitute capacitors in Spice) but might come in handy someday, and I 
mostly trust my own soldering. Maybe I'll splurge on some better quality 
through-hole caps for it than those ceramic disk....things

I also have their resistance box, which is very good!

I tossed the cap box.

You bought that NEW? Or was it second/third/fifth hand?

It looks like an idiot tried to modify it. I have trouble imagining a 
legitimate company letting something that hacked out for sale.

New, from Amazon. It arrived that way. I opened it because it didn't
work right.

Perhaps it was a return from a customer who had a problem, then tried to 
fix it - botched it up, then sent it back to Amazon for a refund. The 
seller didn't bother to test or it simply was repacked in the Amazon 
warehouse for reshipment.

Much like the people who buy clothes for a party then return them 
afterwards...

I bought a guitar amp used many years ago where the previous owner had 
either accidentally or deliberately left inside the speaker enclosure a 
couple photos someone had taken of what appeared to be the previous 
owner, a heavy-set jolly-looking African American man eating dinner in 
his kitchen with what looked like a plate of ribs sitting on top of the amp.

Sadly that amp was stolen from me a number of years ago along with the 
Polaroids that i'd left in it where I found them for some superstitious 
reason. Back into the "material continuum"

Strange, in

  I see a position marked as R5 with a capacitor in it...
Maybe they use the same board for resistor bank and capacitor bank?

It is a good argument (the other pics) to use flexible wires from switches etc to the PCB,
not use PCB mounted / soldered user controls.
After some switch rotations the solder joints will make bad contact.

Eek! I'd like to see some insulator other than air between the AC
nodes of that bridge rectifier, it doesn't look like the gap is very
much at all.

You can't see it properly from that angle which I admit looks alarming. 
If you could view it in 3D, you'd see there's plenty of clearance between 
those leads and they're very rigid, plus this is the low voltage/high 
current one and the applied voltage from the mains transformer across 
that secondary winding is only around 3.3V. 
I admit it's ugly, but it does the job fine and should last much longer 
than the failed monolithic bridge it replaces.

Not even close.  I hold that honor.  Long ago I soldered a 25-pin RS232 
cable.  The blobs were so big I couldn't get the housings on.  I didn't 
think any of the pins were shorted, but I wasn't positive.  I brought 
the cable along when we visited a friend with hardware skills.  While we 
were talking he casually unsoldered my botched job and resoldered it 
nicely.  I probably never soldered again :-(

My uncle Sheldon had a TV repair shop and used to babysit me, but he
couldn't solder because he always had a beer in one hand and a
cigarette in the other. So I sat in his lap and soldered for him,
starting about the age of 3.

That is nothing, even before I was borm I would stick my hand out of mama's and grap the iron to practice soldering.

Good Lord! I had no idea you were such a precocious child, Jan! ;-)
