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.
