How to Use Luowei LW-SP1-199 for Best Results

  1. Prepare the PCB: Clean the board thoroughly to remove dust, oxidation, or old flux.

  2. Apply Paste Evenly: Use a syringe or stencil to apply a thin, uniform layer of paste to the pads.

  3. Place Components: Carefully position SMD or BGA components using tweezers or a vacuum tool.

  4. Heat Solder: Use a reflow oven or hot air station to heat gradually to around 220–230°C.

  5. Inspect Joints: After cooling, check for smooth, shiny solder joints under a microscope.

  6. Clean Residue: If necessary, use flux cleaner or isopropyl alcohol for final cleanup.

For best results, store refrigerated and allow the paste to return to room temperature before each use.
