The solder paste
is loaded into a small syringe and the needle has been cut short. The
manufacture states that the paste has a working time of 8 hours.
Because of the extremely small quantity of paste required for each
surface mount pad, one syringe should be enough to build the entire SSA
project. The syringe should be stored in a safe cool compartment of a
refrigerator.
 The
syringe comes with a 23Ga. needle. Some users find this
needle a little bit to small and requires to much
pressure on the plunger of the syringe. A
larger needle,
21Ga., is now available for purchase.
A second reason for
purchasing additional needle(s) is to replace the original needle
should it become clogged and unusable. Simply replace it with the spare
needle. This should greatly extend the probable life of your solder
paste. I recommend that you buy one of more of the extra
needles
and keep them handy.

The beverage warmer is used to pre-warm the whole
printed circuit boards to a temperature of a about 90 deg. C This
little warmer uses only 9Watt so that it is slow to warm, takes about
10 minutes, but because it is limited in power can't overheat. Used to
gradually heat your PCB after the solder paste and components have been
applied. The beverage warmer is useful while making manual repairs to
the PCB, it adds some heat to overcome the heat spreading of the ground
plane copper in RF boards.
