MECHANIC iSm3 3ML 138℃ Specific Paste For Jump Wire

 

It’s a special solder paste (“jump-wire paste” / “solder tin paste”) designed for electronics work — especially delicate tasks like soldering jumper wires, fly-lines, or small connections on PCBs (e.g. phone motherboards). 

 

The package is 3 mL volume.

 

Its intended melting / soldering temperature is ≈ 138 °C (some sources mention a working range up to ~158 °C) — comparatively “low temperature” for solder pastes. 

 

 

🔧 Key Features & Benefits

 

 

High activity and good wetting: The paste is formulated so solder wets the metal surfaces easily and bonds reliably — essential for small, delicate joints.

 

Moderate viscosity: The paste is neither too runny nor too thick — this helps precise application (especially with fine solder needles) and prevents unwanted spreading or solder bridging. 

 

Easy tinning: The paste allows soldering by merely touching with a soldering iron — the solder adheres (“tins”) reliably with minimal effort. 

 

Good for fine, small-scale soldering jobs: Because of its low melting point and controlled flow, it’s ideal for jump-wire soldering, fly-lines, micro PCB repairs — situations where heat sensitivity and precision matter. 

 

 

⚙️ Typical Use Cases

 

 

Repairing or installing jumper wires on mobile-phone motherboards or small electronics. 

 

Micro soldering — e.g. repairing broken PCB traces, fly-lines, small pads or connectors. 

 

Situations where you need low-temperature soldering to avoid damaging sensitive components. (Because 138 °C is relatively gentle compared to high-temp solders.)
