Chip Resistor
NOTICE
● RECOMMENDED USAGE OF THE RESISTOR
▶ Reflow Soldering
After printing solder creams on PCB, place the resistor on the solder cream.
Then heat the PCB. <Fig 16>
● CAUTION
▶ Flow Soldering
After mounting the resistor to PCB with paste, dip the PCB into solder bath. <Fig 15>
▶ Storage condition
Please make sure to keep the storage conditions.
* Temperature : 5℃∼40℃, * Humidity : 20%RH ∼ 70%RH
▶ Damage control
Please handle with care to prevent damaging the resistor.
Specially, the excessive nozzle height of SMD or the extreme pressure with tweezers.
▶ Leaching prevention
It is important to keep the soldering conditions to prevent Ag leaching in Flow soldering.
