Medium Wave Soldering Machines
Medium wave soldering machines are a type of wave soldering machine that falls between the size and capabilities of a small wave soldering machine and a large-scale wave soldering machine. This type of machine is used in electronics manufacturing to solder through-hole components onto printed circuit boards (PCBs) using a controlled wave of molten solder. It’s suitable for moderate production volumes and offers a balance between efficiency and flexibility.

Key Features and Components of Medium Wave Soldering Machines
Medium wave soldering machines consist of the following key components and features:
Solder Wave Generator
Similar to other wave soldering machines, the medium wave soldering machine has a solder wave generator that creates a controlled wave of molten solder for soldering component leads to PCB pads.
Conveyor System
The PCBs with through-hole components are transported over the solder wave using a conveyor. The conveyor speed and angle can be adjusted to optimize the soldering process.
Fluxing System
A flux application system is used to apply flux to the through-hole components or PCBs before they pass through the solder wave. Flux helps improve solder wetting and bonding.
Preheating Zone
The preheating zone gradually raises the temperature of the PCBs and components before they reach the solder wave. This step reduces thermal shock during solder wave contact.
Solder Wave Nozzle
The solder wave nozzle directs the controlled wave of molten solder. As the PCB passes over the solder wave, component leads make contact with the wave, forming solder joints with the PCB pads.
Cooling Zone
After passing through the solder wave, the PCB enters a cooling zone where the molten solder solidifies, creating reliable solder connections.
Control Unit
The control unit manages key parameters of the machine, such as conveyor speed, solder wave temperature, preheating temperature, and flux application. This ensures consistent soldering quality.
Advantages of Medium Wave Soldering Machines
Some of the advantages of medium wave soldering machines include:
Moderate Capacity
It’s suitable for mid-range production volumes, offering better efficiency compared to smaller machines.
Flexibility
Medium wave soldering machines can handle a range of PCB sizes and through-hole components.
Quality
Controlled solder wave and parameter management contribute to reliable and consistent solder joints.
Limitations of Medium Wave Soldering Machines
Some limitations to consider are:
Cost
Medium wave soldering machines are more expensive than smaller wave soldering machines.
PCB Layout
The PCB layout must be compatible with the medium wave soldering machine. For example, the component leads must be spaced far enough apart to prevent solder bridges.
Potential Solder Defects
Medium wave soldering machines may be more prone to solder defects than larger machines. This is because the smaller size of the machine can make it more difficult to maintain consistent temperature and solder flow.
Applications of Medium Wave Soldering Machines
Typical applications include:
Medium Volume Manufacturing
When production volumes are in the thousands of boards per month range, medium wave soldering provides efficient throughput.
Flexible Production Lines
Medium wave soldering machines allow frequent product changeovers on shared production lines.
Prototype to Production Transition
The same medium wave soldering machine can be used from initial prototyping through ramp up to medium volume production.
Buying Considerations for Medium Wave Soldering Machines
Important factors when selecting a medium wave soldering machine:
Production Volume
Consider current and expected production volumes to choose an appropriately sized machine.
Variety of PCBs
If a wide range of PCB types will be processed, select a machine that can accommodate this flexibility.
Budget
Medium wave soldering machines range in cost from tens of thousands to over a hundred thousand dollars.
Available Space
Measure the floor space in your facility to ensure the machine will fit.
Ease of Use
Look for a machine with intuitive controls and settings menus to simplify operation.
Maintaining and Operating Medium Wave Soldering Machines
To maximize performance, follow best practices:
Calibration
Regularly calibrate the temperature sensors, mechanical components, and conveyor.
Cleaning
Follow scheduled cleaning protocols to remove solder flux residues and debris.
Parameter Adjustments
Tune conveyor speed, wave height, and other parameters to optimize solder joint quality.
Safety
Wear protective equipment when working around the molten solder. Follow safety procedures.
