Wave soldering has been around a long time and is the primary method of soldering components to printed circuit boards. Here’s a list of the latest wave soldering systems available in India.

Earlier, printed circuit boards were larger and practically all of them were sparsely populated with through-hole components. This enabled an automated method to manufacture a huge number of boards extremely fast. PCB manufacturers basically use reflow for SMDs, wave soldering for through-hole components, or both for large scale board assembly. The method or methods most applicable depend on the PCB’s design. In the wave soldering process, the PCB is passed over a pan of molten solder in which a pump produces an upsurge of solder that looks like a standing wave, and hence the name. By looking at the advantages and disadvantages of wave soldering solutions, we can determine when to use them.

Now, let’s find out more about some of the top SMT wave soldering models available in the market today.

Model: Ersa POWERFLOW PRO; Manufacturer: Kurtz Ersa, Germany
Based on stable processes and reproducible parameters, Ersa wave soldering systems offer quality, cost, service and prompt delivery. Being a member of the POWERFLOW family, the Ersa POWERFLOW PRO is a high-performance, full tunnel wave soldering system with state-of-art nitrogen technology. The POWERFLOW PRO comes with a well-coordinated fluxer, preheater and soldering module. Thanks to the available spray fluxers with intelligent spray pattern programming, users benefit from low flux consumption and optimised processing speeds. On the preheating side, the POWERFLOW PRO offers convection heating as well as heating modules with medium and short-wave infrared emitters.

Key features:

  • The infrared emitters react dynamically and are therefore ideally suited for mixed production.
  • POWERFLOW PRO can be adapted to diverse product requirements while the length and output of the preheating section can also be retrofitted.
  • The user-friendly unit can be optimally adapted to the corresponding application by various combinations of the soldering nozzles.
  • The heart of the POWERFLOW PRO is the soldering module with its double wave soldering technology enabling long wetting times and high wave heights.

The Vitronics Soltec Delta X has evolved from a long heritage of soldering machines with thousands in production worldwide. With technology driven features developed over generations, the Delta X is a reliable, dependable and cost-efficient wave soldering machine.

Key features:

  • Up to three products can be processed simultaneously for maximum throughput.
    Conveyor system–parallelism: A robust conveyor and chains keep the assembly interface with the wave equal and parallel.
  • Multiple lead-screws that are mechanically driven ensure parallel rails: Parallel to 1.0mm.
    Solderpot blocking system guarantees repeatable positioning.
  • A conveyor system ensures repeatable interfacing of the product to the solder waves.
    Thermal expansion systems on the entrance end allow for smooth operation.
    Fluxing unit: Pressure controlled flux supply with stepper motor for precise, repeatable flux application.
  • Preheater: Preheat configurations for process flexibility: IR calrod, quartz lamps and forced convection. Modules are easily exchangeable and configurable in the software.
  • Solderpot: Titanium one word components with unique dross management design.
    Heavy duty titanium fingers: Standard HD fingers dramatically reduce finger replacement.
  • The flexible chain allows for smooth interface and will not warp the assembly due to the thermal expansion.
  • Crash detection ensures proper loading and unloading of the PCB in the fingers.
