THESE AREAS SOLDER BRIDGES

A solder bridge between two adjacent foils is shown ._
in photograph A. Photograph B shows how the con-
nection should appear. A solder bridge may occur if
you accidentally touch an adjacent previously sol.
dered connection, if you use too much solder. or if
you drag" the soldering iron across other foils as you
remove it from the connection. A good rule to follow
(iagggméFgggflrgéngfipvmeTEC-non is: always take a good look at the foil area around each
22mg SPECIFIED VOLTAGE AND cdlnsgfi lead before you solder it. Then, when you solder the

' 9 connection, make sure the solder remains in this area
and does not bridge to another fail. This is especially
important when the foils are small and close together.

.NOTE: It is alright for solder to bridge two connec-
tions on the same foil.
