■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 apply-ing 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.
