Homebrew PCBs

I was sooo surprised how easy SMD is compared to how tough it looked.
The key to my success so far is to use *SOLDER  PASTE*.  Look for it
through google and/or Ebay. Pay attention to what you order because some
solder flux's are labeled "Solder Paste Flux". As I understand it, there
is liquid flux, flux paste (sticky flux) , and solder paste.  The solder
paste consist of a flux paste with tiny solder balls inside. I'm
currently using a solder paste from overseas. It's called something like
"Mechanics Solder Paste" and its model number is MCN-300. This stuff
rocks !  I've bought a few 50 gram jars, had my wife stuff some in a big
fat syringe and screw on a 19 gauge *blunt tip* needle. I remember
reading that the solder paste must be kept in the refrigerator while
not being used. I think it's something to do with the flux.

 

Also be sure to purchase a 20x - 45x  magnifier:

Subject: [Homebrew_PCBs] Flux suggestions

 

  

OK folks, I have decided to take the plunge into building PCB's with SMD
components. I have been putting this off for about 3 years now, but the
availability of new parts in through hole configurations is undeniably
reducing.

Having watched many youtube videos, it seems the most important part of
the process is the flux, however, having never bought flux outside of
flux
cored solder, I am at a loss for what I should be looking for in a flux.
It appears that while no-clean flux has the appeal of not needing a
clean
up step, activated solder is easier to use. Should I be looking at a
liquid or paste flux?

I realize that there are probably as many opinions about this as there
are
list members, but I would like to draw on the experience of the group
and
hear suggestions...

Thanks

Anthony
