Preheating can be helpful for multilayer or copper-rich printed circuit boards if the assembly dissipates a significant amount of heat from the actual rework area. This means that the required temperature rise does not have to be generated solely locally by the rework tool.
The FR-850 is designed for precise micro-hot-air applications involving very small SMD components. The FR-810B and FR-811 offer significantly higher heating power and airflow for larger or more thermally demanding rework tasks. The FR-811 complements this approach with more extensive process control and monitoring capabilities.
Hot air is particularly suitable for components where multiple solder joints must be melted simultaneously or where individual connections cannot be reached effectively with a soldering tip. These include, for example, QFP or BGA applications.
That depends on the component geometry and accessibility. Small two-pin components, for example, can be worked on with micro soldering tweezers. For very small or closely spaced components, precise micro hot air, such as that provided by the HAKKO FR-850, may be more suitable.
Automated processes operate using defined positions and motion sequences. The soldering tip must therefore make reproducible contact with the solder joint and the terminal. In the case of K-type soldering tips with a groove, the geometry also influences how solder is held in the tip’s working area and applied to the solder joint.
The width should be suited to the geometry and arrangement of the connections, as well as the available installation space. In addition, the contact area, heat requirements, and the amount of solder needed must be taken into account. Therefore, a tip that is as wide or as narrow as possible is not necessarily the better solution.
No. Drag soldering is one possible process method, for example, in terminal strips. Depending on their geometry, K-tips with a groove can also be used for individual solder joints, as demonstrated by applications involving microswitches and ultrasonic sensors.
Solder can be held in the groove within the working area of the soldering tip. Depending on the application, this solder can be applied during a guided motion or at a single solder joint. The width and depth of the groove must be appropriate for the specific soldering task.
Depending on the model, K-series soldering tips with a groove are suitable for applications such as terminal blocks, connectors, microswitches, and sensor connections. The appropriate model depends on the solder joint geometry, heat requirements, the amount of solder needed, and the motion sequence.
