Does anyone know how solder paste is made? Is it simply solder particles in
a flux paste? What is the general method of creating the particles?
Solder balls (particles) used in solder paste are very tightly
controlled elements of what makes up a solder paste.
Their size and make up are precision controlled.
They are probably made by spraying molten solder mist inside a vacuum
chamber or other air free environment.
Little tiny balls of solder...
Then they sieve it and classify the balls, and recycle those that do
not go through the sieve.
