HAKKO T18 Series Soldering Tips Instruction Manual

1. Introduction

This manual provides essential information for the proper use and maintenance of your HAKKO T18 series soldering tips. These tips are specifically designed for use with HAKKO FX888D and FX888 soldering stations, ensuring optimal performance and longevity. Adhering to these instructions will help you achieve high-quality solder joints and extend the lifespan of your soldering tips.

2. Setup and Installation

Proper installation of the soldering tip is crucial for safe and effective operation.

2.1 Compatibility

HAKKO T18 series soldering tips are exclusively compatible with HAKKO FX888D and HAKKO FX888 soldering stations.

2.2 Installation Steps

1. Ensure your soldering station is powered off and completely cool before handling the soldering iron or tip.
2. Select the appropriate T18 series tip for your soldering task.
3. Carefully insert the chosen tip into the heating element of the soldering iron. Ensure it is fully seated.
4. Secure the tip according to your soldering iron's specific design (e.g., tighten a retaining nut or sleeve). Do not overtighten.
5. Once the tip is securely installed, you may power on your soldering station. Allow the iron to reach the desired temperature.

3. Operating Instructions

Follow these guidelines for effective and safe soldering.

3.1 Initial Tinning (New Tips)

Before first use, or after prolonged storage, new tips must be properly tinned to prevent oxidation and ensure efficient heat transfer:

1. Heat the tip to its operating temperature.
2. Apply a small amount of solder to the entire working surface of the tip until it is fully coated.
3. Wipe off excess solder with a damp sponge or brass wool.

3.2 Temperature Setting

Set your soldering station to the appropriate temperature for the solder and components you are using. Refer to your solder's specifications for recommended temperatures. Generally, lead-free solder requires higher temperatures than leaded solder.

3.3 Soldering Technique

1. Clean the tip immediately before soldering.
2. Apply the tip to both the component lead and the PCB pad simultaneously to heat them evenly.
3. Feed solder onto the heated joint, not directly onto the tip. Allow the solder to flow naturally around the joint.
4. Remove the solder wire, then remove the soldering iron.
5. Allow the joint to cool undisturbed.

3.4 Tip Selection

Different tip shapes are suited for various applications:

• T18-B (Conical): General purpose, fine point for precision work.
• T18-C2 (Chisel): Versatile, good for general soldering and drag soldering.
• T18-D32 (Chisel/Screwdriver): Wider chisel for larger pads and components.
• T18-K (Knife): Ideal for drag soldering, surface mount components, and cutting solder bridges.
• T18-BR02 (Bent Conical/Bevel): Angled tip for reaching tight spaces and specific component types.

4. Maintenance

Regular maintenance extends tip life and ensures consistent performance.

4.1 Cleaning

• During Use: Wipe the tip frequently on a damp cellulose sponge or brass wool to remove excess solder and flux residue.
• After Use: Always re-tin the tip with a fresh coat of solder before turning off the station. This protects the tip from oxidation.
• Avoid: Do not use abrasive materials like sandpaper or files, as this will damage the tip's plating.

4.2 Re-tinning

If a tip becomes oxidized (dark and solder won't stick), try re-tinning:

1. Clean the tip thoroughly.
2. Apply a tip tinner/activator compound, or generously apply fresh solder while rubbing the tip on a damp sponge or brass wool.
3. If oxidation persists, the tip may need replacement.

4.3 Storage

Store tips in a dry, clean environment. Keep them away from corrosive chemicals or excessive humidity.

4.4 Inspection

Periodically inspect tips for signs of wear, pitting, or severe oxidation. Replace tips that are significantly degraded to maintain soldering quality.

5. Troubleshooting

Common issues and their potential solutions.

• Tip not heating:
  - Check if the soldering station is powered on and the iron is properly connected.
  - Ensure the tip is correctly seated in the heating element.
• Solder not sticking to the tip (poor wetting):
  - The tip is likely oxidized. Clean and re-tin the tip thoroughly (refer to Section 4.2).
  - Ensure the soldering temperature is adequate for the solder being used.
  - Check if the tip's plating is worn out; if so, replace the tip.
• Poor solder joints (cold joints, insufficient flow):
  - Verify that the soldering temperature is correct.
  - Ensure the tip is clean and properly tinned.
  - Improve your soldering technique to ensure both the component lead and pad are heated simultaneously and sufficiently.
• Excessive tip wear or pitting:
  - This can be caused by using too high a temperature, prolonged contact with components, or using highly active fluxes.
  - Ensure proper cleaning methods are used (avoid abrasives).
  - Consider replacing the tip if wear is significant.

6. Specifications

6.1 T18-BR02 Tip Dimensions

As shown in Figure 2, the T18-BR02 tip features specific dimensions for precision work, including a radius of 0.2mm, a 30-degree angle, a tip length of 4mm, and an overall working length of 10.5mm.

7. User Tips

• Always ensure your soldering iron tip is clean and well-tinned before and after each use. This is the single most important factor for tip longevity and good soldering results.
• Use the lowest possible temperature that allows the solder to flow freely. Higher temperatures accelerate tip oxidation and wear.
• Match the tip shape and size to the component and pad you are soldering. Using an oversized tip for small components or an undersized tip for large components can lead to poor heat transfer and damaged parts.
• Avoid applying excessive pressure to the tip. The goal is heat transfer, not mechanical force.
