Built For DIP Production
An Automatic Wave Soldering Machine is used when a factory needs repeatable soldering for through-hole components, DIP assemblies, and mixed SMT+DIP boards. Acrab 450 is designed for wider PCB production, giving manufacturers stable flux coating, controlled preheating, accurate transportation, and reliable double-wave soldering in one continuous process.

Many factories upgrade from manual soldering because quality becomes difficult to control when production volume increases. Common issues include bridging, insufficient solder, solder balls, poor hole filling, unstable wetting, and operator-to-operator variation. These problems may look small at first, but once boards enter mass production, they become real cost monsters.
The I.C.T Acrab 450 Lead-free Wave Soldering Machine is built to make the process more stable. The spray section uses a Japan Kuroda nozzle and step motor movement for uniform flux coating. The 3-zone preheating system helps activate flux and reduce thermal shock before the PCB reaches the solder wave. The conveyor supports adjustable speed, height, and 4–7° angle control, helping different PCB types move through the machine smoothly.
For factories producing power supplies, automotive electronics, communication boards, LED products, home appliance control boards, and industrial electronics, Acrab 450 works as reliable DIP Wave Soldering Equipment for medium and larger PCB production.
Wave Soldering Features
Spray Control
Precise Flux Application
The spray system is a key part of Acrab 450 because flux quality directly affects final soldering results. This PCB Wave Soldering Machine uses a high-precision Japan Kuroda nozzle to support uniform flux coating across the PCB surface. Stable flux coverage helps reduce common DIP soldering issues such as poor wetting, solder bridges, and inconsistent hole filling.
The system uses step motor control instead of simple cylinder movement, giving better motion stability during long production runs. Its modular drawer-type structure also makes access easier for cleaning and maintenance. With automatic cleaning, filtering, and exhaust design, operators can keep the spray area cleaner and reduce daily maintenance pressure.
Thermal Performance
Stable 3-Zone Preheating
Acrab 450 uses a 3-zone preheating structure with hot air and IR heating. This design helps the PCB temperature rise more evenly before entering the solder wave. Good preheating is important because it activates the flux, removes solvent, reduces thermal shock, and helps the solder wet component leads more reliably.
For a High Stability Wave Soldering Machine, temperature control cannot be random. Acrab 450 uses PID+SSR control to support accurate preheating performance. The modular preheating structure and drawer-type maintenance design also make service easier. Top preheating can be selected when the production process requires additional thermal support for more demanding PCB assemblies.
Conveyor Accuracy
Smooth PCB Transportation
The conveyor system of Acrab 450 is designed to keep PCB movement stable from entry to soldering. It uses a synchronous board-feeding structure to reduce the risk of board jamming or falling after the PCB enters the rail. This is useful for wider or heavier PCB assemblies, especially in continuous DIP production.
The conveyor supports 50–450mm PCB width and 0–2000mm/min speed adjustment. The rail height and angle can also be adjusted according to process needs, with a 4–7° conveyor angle range. Heavy-duty spring pressing fingers are available to improve board holding stability, while the cleaning function helps reduce contamination during production.
Soldering System
Reliable Double-Wave Soldering
The soldering section of Acrab 450 is built for stable double-wave soldering performance. The solder flow channel design helps keep the wave peak stable, reducing soldering defects caused by unstable wave contact. For through-hole components, consistent wave height and smooth solder flow are essential for better hole filling and more uniform solder joints.
Acrab 450 uses a cast iron solder pot with one-piece molding to reduce deformation risk. The surface has an enamel ceramic coating for longer service life. The 500kg lead-free solder pot supports continuous production, while optional functions such as automatic tin addition, nitrogen protection, and electric tin pot movement can be selected based on production requirements.
Smart Operation
PC And PLC Control
Acrab 450 uses a PC+PLC control system to make operation clearer and more standardized. Operators can manage key process parameters such as temperature, conveyor speed, spray settings, ventilation, and alarm records through the system. This helps reduce dependence on personal experience and makes production easier to repeat across different shifts.
The machine also supports traceable alarm records, over-temperature protection, independent air switch protection, and automatic standby operation. When the machine is idle, standby mode helps reduce tin slag generation and energy consumption. For factories looking for a stable Automatic Wave Soldering Machine, this control system makes daily production less “guess and pray.”

FAQ
What is a Double-Wave wave soldering machine?
A Double-Wave wave soldering machine is used for soldering through-hole components on PCB assemblies with two solder waves. The first wave helps improve solder penetration and wetting, while the second wave helps smooth the solder joints and reduce defects. It is commonly used in DIP lines and mixed technology PCB assembly where SMT components and through-hole components exist on the same board. For factories producing power supplies, control boards, LED boards, or automotive electronics, double-wave soldering is often more stable than simple manual soldering.
When should I choose wave soldering instead of manual soldering?
You should choose wave soldering when your production volume, quality requirement, or consistency target is higher than what manual soldering can reliably handle. Manual soldering may work for samples or very small batches, but it depends heavily on operator skill. A Double-Wave wave soldering machine controls flux spraying, preheating, conveyor speed, solder wave contact, and cooling in one continuous process. This helps reduce human variation, improve repeatability, and make production easier to manage.
What PCB products can use this machine?
This machine can be used for many through-hole and mixed assembly PCB products, including power supplies, consumer electronics, communication electronics, industrial control boards, automotive electronics, LED products, and home appliance control boards. The I.C.T Acrab series supports different PCB widths, including 50-350mm, 50-450mm, and 50-615mm depending on the model. This gives factories more flexibility when choosing a machine for current products and future board size changes.
How does preheating affect soldering quality?
Preheating directly affects soldering quality because it prepares the PCB, flux, and component leads before they contact the solder wave. If preheating is too weak, flux may not activate fully, and solder wetting can become unstable. If preheating is too aggressive, sensitive components may face unnecessary thermal stress. I.C.T uses a 3-zone hot air/IR preheating system to support a more stable temperature rise. This helps reduce solder balls, poor wetting, and inconsistent through-hole filling.
Why is flux spray control important?
Flux spray control is important because uneven flux can cause uneven soldering results. Too little flux may lead to poor wetting, while too much flux can create residue, contamination, or more cleaning work. The I.C.T Double-Wave wave soldering machine uses a high-precision spray nozzle and step motor control to improve flux coating stability. The system also supports adjustable flux flow and automatic cleaning, helping operators keep the spray process more controlled during daily production.
What is the advantage of a cast iron solder pot?
A cast iron solder pot provides better mechanical strength and long-term stability for high-temperature soldering operation. In the I.C.T wave soldering machine, the solder pot uses a one-piece cast iron structure to reduce deformation risk. The surface has enamel ceramic coating, which helps extend service life and improve durability. For customers running lead-free soldering, a stable solder pot structure is important because the process temperature is higher and daily operation time can be long.
