T38 Series
Soldering and Desoldering Tips
The Hakko T38 series covers composite soldering tips for compatible Hakko irons, available in two temperature classes: 400°C (T38-02x) and 350°C (T38-03x). The range spans the tip shapes I (straight), IS, J (angled), JS, K (knife), 1L and 2L. The "Composite" designation refers to the multi-layer tip construction of copper base, iron coating and chrome protection, which ensures longer service life and consistent heat transfer.
| Type | Shape | Temperature |
|---|---|---|
| T38-02I | I (straight) | 400°C |
| T38-02IS | IS | 400°C |
| T38-02J | J (angled) | 400°C |
| T38-02JS | JS | 400°C |
| T38-02K | K (knife) | 400°C |
| T38-02L1 / T38-02L2 | 1L / 2L | 400°C |
| T38-03I to T38-03L2 | Same shapes | 350°C |
The composite construction (copper core, iron shell, chrome plating) improves heat transfer efficiency and protects the tip against oxidation and solder corrosion. The I shape is suited for spot soldering on fine pads, J and JS for angled access positions, K (knife) for removing solder bridges, and the L1/L2 shapes for work with defined solder volumes. The temperature class (400°C vs. 350°C) is selected according to the solder alloy and thermal sensitivity of the components.
Typical applications: Hand soldering on SMD components in electronics manufacturing and rework, precision soldering on ICs and fine-pitch parts, PCB repair in production and laboratory, hand soldering with lead-free solder (higher temperature class 400°C), and work on heat-sensitive components (350°C variants). The compact L1/L2 geometry is suited for solder-depot work.
