Homebrew PCBs

I recently had a chance to use some solder (intended for electronic use)
containing water-soluable flux.  That stuff is wonderful!  It solders
just as well as rosin-core solder.  What is so great is that the flux
can be removed very easily by just rubbing gently with a water-soaked
paper towel.  The flux should be washed off ASAP (within about four
hours of soldering) to avoid tarnishing the copper traces and solder
joints.

 

There are also water-based "flux pens" that look like felt-tipped Magic
Marker ink pens, that can be used to apply flux to the PCB.  This is
especially useful for soldering surface mount ICs.

 

Enjoy!
