Small Wave Soldering Machine
It’s suitable for small volume of soldering production, with economic power consumption, 2 preheating zones are available.
What’s more, its compact structure design can save more assembly footprint and totally offers a lower budget, which is perfect for the small-size factories or start-ups.
Small Wave Soldering Machine
Small wave soldering machines are a type of soldering machine that uses a controlled wave of molten solder to solder through-hole components onto circuit boards. They are particularly suitable for small-scale production or for boards with a limited number of through-hole components.
Small wave soldering machines offer a number of advantages over manual soldering methods, including:
Increased efficiency
Improved consistency
Reduced risk of defects
Lower cost
Key Components and Features
Small wave soldering machines consist of the following key components and features:
Solder Wave Generator
This is the heart of the machine. It generates a controlled wave of molten solder, typically using a solder alloy with a relatively low melting point (such as tin-lead or lead-free solder).
Conveyor System
The PCBs with through-hole components are transported over the solder wave using a conveyor. The speed and angle of the conveyor can be adjusted to achieve the desired soldering results.
Preheating Zone
Just before the solder wave, there is usually a preheating zone. This helps to preheat the PCB and components, which promotes better soldering and reduces thermal shock.
Solder Wave Nozzle
The solder wave nozzle directs the molten solder in a controlled manner, ensuring it comes into contact with the component leads and the PCB pads that need to be soldered.
Cooling Zone
After passing through the solder wave, the PCB enters a cooling zone where the solder solidifies, forming reliable solder joints.
Flux Application System
Flux is often applied to the through-hole components before they pass through the solder wave. Flux helps to remove oxides from the surfaces being soldered, improving the soldering quality.
Control Unit
The control unit manages various parameters of the machine, including conveyor speed, solder wave temperature, and preheating temperature. This ensures consistent soldering results.
Advantages of Small Wave Soldering Machines
Small wave soldering machines provide several advantages:
Efficiency
The wave soldering process is relatively fast, making it suitable for moderate production volumes. It is much faster than manual soldering.
Reliability
Controlled solder wave ensures consistent and reliable solder joints. The automated process avoids human errors.
Cost-Effectiveness
Small wave soldering machines are often more affordable and space-efficient compared to larger wave soldering systems. The lower capital cost makes them very cost effective.
Versatility
They can handle a variety of through-hole components and PCB sizes. One small machine can support various products.
Limitations of Small Wave Soldering Machines
However, small wave soldering machines also have some limitations:
Not suitable for components sensitive to heat or for densely populated boards.
Can potentially lead to overheating or solder bridges between closely spaced leads.
Careful design is required to avoid these issues.
Case Studies
Small wave soldering machines have been used successfully in many applications:
A small wave soldering machine was used to solder the through-hole components on a circuit board for a medical device. The machine was able to solder the components quickly and accurately, resulting in a high-quality product.
A small wave soldering machine was used to solder the through-hole components on a circuit board for a consumer electronics product. The machine was able to solder the components quickly and cost-effectively, resulting in a product that was affordable for consumers.
