Which tip should I choose for soldering small surface-mount (SMD) components?

You should choose the Pointed Tip (5SI-B165-T) for SMD work. Its fine conical shape allows you to apply heat to individual tiny pads without accidentally bridging solder to adjacent pins.

How do I replace the tip on my SI-B165 soldering iron?

To replace the tip, ensure the iron is completely powered off and cooled down, then simply pull the old tip straight out of the socket and push the new one firmly into place.

Can I pick up these replacement tips today in Hong Kong?

Yes, both the Pointed and Knife variations are regularly stocked at our Sun Cheong Computer Co. Ltd. physical store in Sham Shui Po for instant pickup.

Can I use sandpaper to clean the black oxidation off this tip?

No, you should never use sandpaper or abrasive files on soldering tips. Doing so will instantly destroy the protective iron plating, rendering the tip useless and unable to hold solder.

Full Product Description

Genuine Replacement for Pro'sKit SI-B165

This replacement tip is engineered specifically to fit and function flawlessly with the Pro'sKit SI-B165 portable soldering iron. Over time, soldering tips oxidize and lose their heat transfer efficiency, leading to cold solder joints and frustrating repair sessions. By installing a brand-new, factory-original tip, you instantly restore your soldering iron's rapid heating capability and precision, ensuring professional-grade results for all your electronic projects.

Choose Your Profile: Pointed vs. Knife Edge

Selecting the correct tip profile is crucial for maximizing your soldering efficiency and protecting delicate components. The Pointed Tip (5SI-B165-T) features a fine, conical shape that is ideal for precision through-hole components, tiny SMD resistors, and intricate PCB trace repairs. Conversely, the Knife Tip (5SI-B165-K) offers a larger surface area, making it the perfect choice for drag soldering multiple IC pins, tinning thicker gauge wires, or removing solder bridges with copper wick.

Pro Tip from Our Technicians

Always tin your new soldering tip with fresh solder immediately upon its first heat-up to prevent premature oxidation. Our Sham Shui Po repair specialists recommend keeping a generous coating of solder on the tip before turning off the iron, as this sacrificial layer protects the underlying plating from degrading over time.
