■ Soldering the resistor with too much solder or too little solder results in the poor reliability of the solder connection of the
resistor. Use the proper volume of solder in the soldering process. Sufficiently check for the volume of solder used.
■ Soldering with high bond strength or special property solder may affect the quality of the resistor. Do not use such solder.
■ Use rosin-based solder flux. When using highly active solder flux made mainly of halogen (chlorine, bromine, etc.), flux
residues may affect the performance and reliability of the resistor. Check the effects of flux residues before using the solder
flux. Do not use highly acidic flux, water-soluble flux, or flux containing fluoride ions. When solder flux sticks to the resistor
after the soldering process, the activation energy of the flux may corrode the resistor and cause it to fail. Prevent solder flux
from sticking to the resistor.
Storage conditions
