■ SOLDERING CONDITIONS
When dip-soldering CS-4-13NA, NB or CS-4-22YA, YB,
solder bridges may occur between terminals depending
upon soldering conditions.
In order to prevent such bridges,vertical flow direction is
recommended as shown in the below figure.
For dip-soldering,preheating should be done after applying flux.
Handle carefully in case of parallel flow direction in which
solder bridges occur more often because solder flow
moves toward the vertical direction against the terminals.
In addition, other soldering conditions such as soldering
temperature, preheating temperature, specific gravity of
flux, and belt speed affect the occurrence of bridges.
Depending on flux to be applied, markings may, though at
rare case, disappear or fade out at soldering. Please make
sure before its use.
