MECHANIC 900M-T-K BW SERIES IRON BIT
The Mechanic 900M-T-K (BW Series) is a high-performance soldering iron tip designed for precision electronics repair. Known for its "K-type" (knife-edge) geometry and "Black Diamond" (BW) coating, it is a staple for technicians performing microsoldering, SMD rework, and bridge clearing.

Maintenance & Usage Tips
Pro Tip: To maximize the life of your BW series tip, avoid using high-acidity flux and never file the tip. Filing removes the protective plating and destroys the thermal properties instantly.
-
Initial Tinning: When heating the tip for the first time, apply solder immediately as it reaches melting temperature to prevent "instant oxidation."
-
Temperature Control: Ideally, operate between $350^\circ\text{C}$ and $380^\circ\text{C}$. Continuous use at $450^\circ\text{C}+$ will accelerate the degradation of the black coating.
-
Cleaning: Use brass wool or a damp (not soaking) cellulose sponge.
-
Storage: Always leave a generous "blob" of solder on the tip before turning off the station to create an airtight seal against oxygen.
