cheap solder smoke filter or overkill?...

Have a box fan and, since not being satisfied with existing solder fume
filter because I have to be within 6\" of opening, I purchased one of
these filters and placed across the box fan:

https://www.walmart.com/ip/Filtrete-20x20x1-Allergen-Plus-Odor-Reduction-HVAC-Furnace-Air-Filter-1200-MPR-1-Filter/36728389

Appealed to me since it already has built in charcoal filter as well.
Won\'t be tested until this week. Thoughts?

60/40 solder from any source is wretched stuff. From China or not.

What you want is true eutectic solder, 63/37. Accept no substitutes. Plenty of US sources as well.

Just bought three pounds of vintage (BOW) 63/37 from ebay. $45 for all three including shipping, about as good as I can find.

Is there a good test to determine what mix a solder is? I came across pounds of
large diameter solder likely from a plumber. Not sure what old leaded plumbing
solder was. 50/50 by chance?

The best easy way it to check the melting point. Heat someting up and
measure the temperature then touch the solder to it. Raise the
temperature 10 deg F at a time . There are charts to tell the melting
temperature of the mixes. Most plumbing solder is the 50/50 mix and
usually too thick to do much electronic work.

Standard plumbing solder is flux-free and 50:50 tin to lead. Then, there is Acid Flux plumbing solder that should not be allowed in the same county as electronic solder. You can determine which is which by cutting off the end. Acid flux solder will have a visible core containing the acid. Typical acid-core solder is 40:60.

If the solder in question is either of those *DO NOT* use it for electronics under any circumstances. And if it is vintage tin/lead solder *DO NOT* even use it for plumbing.

Why is 60/40 Sn/Pb bad? Have had Kester 60/40 as general purpose solder for years.

Why eutectic solder? AFAIK, the only difference is the single melt/freeze point at 183 degrees C vs a melt range of 183-192 C.

Thoughts?

Good idea given and if the goal is to capture the rosin fumes. Greater surface area will capture more fumes. My general approach is to run the ceiling fan in the room - it is a small room, so that is enough to move the fumes away from me. I do not solder enough to justify a dedicated system - perhaps when I retire not so long from now.

Thanks. I will be testing it out tomorrow for soldering. All I did
yesterday was light a match. My nose is normally not the greatest at
detecting odors, but I am sensitive to the burned off chemical from the
matches (I think it\'s phosphorus). Anyway, although not all the smoke
went in as I was standing about 4 feet away, within 5 minutes I could no
longer smell the phosphorus in the room. Normally, the smell would
persist for at least half an hour.

It is the plastic state that leads to cold-solders. The smallest bit of movement during the cooling period (and for 9 degrees C, that can be several seconds) can and will lead to failures as soon as immediately, but more typically over time. Further, many will be invisible. prior to that failure. Further, these sorts of problems tend to include a lot of heat at the bad joint, leading to the potential for cascade failures. Using a true eutectic solder eliminates the concern.

I don\'t understand the obsession with soldering fumes.
I\'ve been soldering for over 50 years now with no ill effects.
I certainly don\'t find the fumes irritating or obnoxious.

You\'re NOT breathing in lead fumes. Lead vaporizes at 3100F.

There are plenty of things I do that I do with good ventilation.
Just soldering isn\'t on my list.

Basically, the issue is paraffin waxes and tars precipitating in the lungs - from whence they are not ejected.

And, Jeff, where you solder, the rosin fumes would not stand a chance! Too much fresh air.

Well, to tell you the truth, I used to not worry about it either in the
days when I could get true 60/40 solder from Radio Shack, but those days
appear to be long gone. The last 8 oz one I ordered this past winter
was from an Ebay vender who carried the \"Chinese\" 60/40. After some
past experiences with Chinese electronics from there (Ebay) burning up,
I am leery to trust the solder so decided to add a $13 filter to the box
fan.

And it isn\'t just solder fumes either. I use a fair amount of heat
shrink. Not sure what most use to heat it, but I like using a plain
match from a match pack. Of course, the phosphorus then smells up the
room for 30 min and sometimes I tend to overheat the heatshrink a bit
with plastic odor, so the other reason for the fan filter.

I\'ll definitely find out how it does today as I have a fair amount of
soldering in store as well as some heatshrinking.
