The 2UUL FD31 C115-K Precision Soldering Iron Tip is an ultra-fine cartridge-style heating bit engineered specifically for C115-compatible micro-soldering stations, nano-rework handles, and precision electronics repair. When servicing dense multi-layer smartphone motherboards, traditional soldering irons suffer from bulky tip-to-grip distances and slow thermal recovery, making it nearly impossible to access recessed BGA pads or drag-solder fine-pitch FPC connectors without bridging adjacent pins. The FD31 C115-K solves this with an integrated heating core architecture and precision knife (K-type) edge profile, delivering targeted heat transfer right where it is needed within seconds.

Manufactured with a premium oxygen-free copper alloy core and finished with a multi-layer anti-oxidation electroplated coating, the FD31 achieves rapid heat-up to 350°C in approximately 2 seconds. Its sharp, angled knife geometry provides versatile multi-surface contact: technicians can utilize the wide flat blade for smooth drag-soldering and desoldering wick pad leveling, or employ the micro-sharp chisel point for tinning 0.01mm jump wires under a microscope. By maintaining tight temperature stability during continuous micro-soldering, the 2UUL FD31 C115-K protects sensitive logic board components from overheating, making it an indispensable bench consumable for mobile repair shops, laptop servicing centers, and micro-soldering laboratories.

Key Features

1. Integrated Heating Core Cartridge: Built-in heating element and temperature sensor provide direct heat conduction with minimal thermal loss.
2. Rapid 2-Second Heat-Up: Reaches operating temperature (up to 350°C) in approximately 2 seconds, with ultra-fast thermal recovery between solder joints.
3. Versatile Knife (K-Type) Geometry: Enables smooth drag-soldering across dense IC pin rows, clean solder wick leveling on BGA pads, and pinpoint jumper wire soldering.
4. Multi-Layer Anti-Oxidation Coating: High-grade electroplated nickel-chromium outer layer resists corrosion, oxidation buildup, and tin erosion for extended tip life.
5. C115 & T115 Station Compatibility: Designed for seamless push-fit compatibility with all standard C115-series soldering handles and nano-soldering stations.
6. Enhanced Micro-Precision Control: Ultra-short tip-to-grip distance minimizes hand strain and micro-tremors, improving precision under high-magnification stereomicroscopes.
7. Low-Temperature Safe Rework: Efficient heat delivery allows technicians to work at lower set temperatures, safeguarding delicate PMICs, baseband circuits, and flex cables.
