Key Performance Features
Internal heating design: Tips heat up 30-40% faster than external heating types. The heating element sits inside the copper core, directing thermal energy to your workpiece instead of wasting it to ambient air.
Oxygen-free copper construction: Achieves 350-400 W/m·K thermal conductivity with temperature capability up to 480°C. Handles both lead-free SAC305 solder (217-220°C melting point) and leaded 63/37 alloys (183°C).
Nickel plating: Provides 3-5x better oxidation resistance than bare copper. RoHS compliant and lead-free for commercial electronics manufacturing.
Protective sleeve system: The outer sleeve fixes the heating core and insulates heat, increasing efficiency by 15-25% compared to exposed tip designs. Heat remains concentrated at the working surface rather than dissipating into ambient air.
How to Choose the Right Tip
For fine SMD work and tight spaces: Use 900M-T-I (fine point) or 900M-T-K (angled access). Perfect for 0402/0603 components, QFP packages under 0.5mm pitch, and PCB rework near tall components. The I-shape concentrates heat into a 0.5-1mm contact zone for precision without thermal damage to neighboring junctions.
For drag soldering and general PCB assembly: Use 900M-T-B (chisel edge). The flat, non-directional contact surface transfers heat uniformly across SOIC pins and small connector rows. The elongated edge excels in confined spaces where vertical tips cannot reach.
For heavy terminals and large joints: Use 900M-T-2C, 3C or D-series (1.2D, 1.6D, 2.4D, 3.2D). The beveled faces hold more solder volume and deliver sustained heat to ground planes, wire-to-board connections, and through-hole components with high thermal mass.
The number in D-tips (1.2, 1.6, 2.4, 3.2) indicates working face width in millimeters—match it to your pad size and thermal requirements.
Critical Maintenance for Long Tip Life
Always keep solder on the tip. Apply fresh solder coating immediately when you power on, and re-tin every 10-15 joints. This oxygen barrier prevents black oxide formation that kills heat transfer.
Use 200-350°C for most work. Temperatures above 400°C accelerate plating degradation and cut tip lifespan by 50-70%. Lead-free solder typically needs 320-350°C; leaded alloys work at 280-320°C.
Clean with brass wool only—never sandpaper. Abrasives remove the nickel plating in seconds, exposing raw copper that oxidizes immediately. One aggressive cleaning with sandpaper can destroy a tip that would otherwise last 200 hours.
Remove black oxide immediately. Use brass wool or tip cleaner compound, then re-tin. If oxide builds up, heat transfer efficiency drops by 60-80%. Never use hard objects or metal files for cleaning.
Store tips with solder coating applied. Keep in a dry environment below 40% relative humidity. This storage protocol prevents corrosion during idle periods and ensures immediate thermal performance when reinstalled.

Getting Started (First Use)
Before soldering your first joint, pre-tin each new tip:
Heat to 300-320°C
Apply rosin-core solder until the entire working surface shows wet coverage
Wipe with brass wool to remove excess
This initial tinning establishes the protective barrier and maximizes heat transfer from day one. The tip comes pre-tinned at the bottom from the factory, but additional tinning before use extends service life.
Why Choose Individual Tips
Purchasing only the tip geometries you actually use prevents inventory waste and reduces upfront costs. For specialized work—such as microelectronics repair requiring only I-tips or power supply servicing needing only D-tips—buying individually makes economic sense.
Workshops can stock multiple quantities of their most-used tip shapes (typically B and K for general electronics) while keeping single backups of specialty geometries. This approach optimizes both budget allocation and workspace storage.
For technicians maintaining equipment across multiple facilities, the 900M-T standardization enables centralized purchasing and cross-location tip sharing without compatibility concerns.
Application-Specific Recommendations
Smartphone and tablet repair: 900M-T-I and 900M-T-K handle fine-pitch connectors, shield can removal, and component-level board repair.
Power supply and audio amplifier work: 900M-T-2.4D, 3.2D, and 3C manage heavy ground connections, transformer terminals, and large capacitor leads.
Prototype PCB assembly: 900M-T-B provides versatility for mixed through-hole and surface-mount designs in limited production runs.
Connector and cable assembly: 900M-T-2C and 900M-T-LD access recessed terminals in D-sub connectors, automotive harnesses, and industrial control panels.
Individual Tip Purchase Details:
Each model sold separately—order the specific geometry required for your soldering applications.
Compatibility Verification: Measure your station’s heating element barrel—it should accept 4.1mm inner diameter tips. Most 900M-format stations from 2010-present use this standard sizing.
Tip Longevity: With proper maintenance (correct temperature, regular tinning, brass wool cleaning), expect 150-300 hours of service life per tip depending on usage intensity and solder alloy type.
