  • Preheating: Assemblies are heated gradually and evenly in the ramp-up zone to a defined temperature. This reduces thermal stress and prepares the solder paste for optimal reflow soldering.

  • Soaking: A constant temperature is maintained to remove oxides from component surfaces and to activate the solder paste flux.

  • Reflow: The temperature is raised precisely until the solder paste melts, creating electrical and mechanical connections between SMD components and the PCB. Accurate temperature management in the reflow oven is crucial here for soldering quality.

  • Cooling: The temperature is carefully decreased to avoid thermal stress, ensuring strong and reliable solder joints.

  • Cold solder joints: Insufficient temperature causes incomplete melting, leading to weak, brittle connections.
    Our solution: Optimized convection with front-and-rear airflow minimizes heat loss and ensures precise control over each zone’s temperature.

  • Tombstoning: Components lift on one side during reflow.
    Our solution: Uniform heat distribution through efficient jet-nozzle design.

  • Voids: Entrapped air reduces conductivity and weakens joints.
    Our solution: Optional ProBot profiling system (OEM by KIC) for optimized temperature profiles and void elimination in demanding SMT soldering.

  • Non-wetting: Poor adhesion of solder to pads results in incomplete joints.
    Our solution: An energy-efficient heating system with improved heat storage for consistently precise temperature control in every zone.

  • Component shift: Movement of components during soldering causes misalignment.
    Our solution: Multiple support points and optional Center Board Support (CBS) with automatic positioning ensure stable transport, especially for large PCBs.
