Instructions:

1. Handling:

   • Handle with care to avoid mechanical damage.
   • Use appropriate ESD (Electrostatic Discharge) precautions to prevent damage.

2. Mounting:

   • Ensure the PCB (Printed Circuit Board) is clean and free from contaminants.
   • Place the resistor on the designated pad using automated pick-and-place equipment or manual placement.
   • Apply solder paste or flux as needed.
   • Solder the resistor using a reflow oven or a soldering iron, ensuring the temperature profile is within the recommended range.

3. Soldering:

   • Preheat the PCB to 120掳C to 150掳C.
   • Peak soldering temperature should be between 230掳C and 260掳C.
   • The soldering time should not exceed 10 seconds.
   • Allow the PCB to cool naturally after soldering.

4. Inspection:

   • Visually inspect the solder joints for proper wetting and absence of bridges or voids.
   • Use a multimeter to verify the resistance value and ensure it falls within the specified tolerance.

5. Storage:

   • Store in a dry, cool place away from direct sunlight.
   • Use within the recommended shelf life to ensure optimal performance.
