How to Use Mechanic TF350 Special Flux Paste for BGA

1. Preparation:

   • Step: Clean the BGA component and the PCB pads thoroughly to remove any dirt, grease, or oxidation.
   • Step: Ensure that the working area is free of contaminants and ready for soldering.

2. Application:

   • Step: Apply a small amount of TF350 flux paste to the PCB pads or the BGA balls.
   • Step: Use a precise applicator or a small brush for accurate placement of the flux paste.

3. Soldering:

   • Step: Position the BGA component onto the PCB, aligning it with the corresponding pads.
   • Step: Heat the assembly using a reflow oven, hot air rework station, or an appropriate soldering tool.
   • Step: Ensure that the temperature profile is suitable for the specific soldering process and that the solder reflows properly.

4. Cooling:

   • Step: Allow the soldered assembly to cool naturally after the reflow process is complete.
   • Step: Avoid rapid cooling, as it may cause thermal stress and potential damage to the components.

5. Cleaning:

   • Step: Clean any remaining flux residue from the PCB using an appropriate flux cleaner or isopropyl alcohol.
   • Step: Inspect the solder joints for quality and reliability, ensuring that there are no defects or issues.
