What Is Flux Cleaning?

Flux cleaning is the process of removing flux residues left on the circuit board after soldering.
In recent years, with the increasing density of component mounting?such as BGA, CSP, and 0201/01005 components?even minute amounts of residue can cause insulation failures, corrosion, and ion migration. As a result, the importance of flux cleaning has grown, particularly in high-reliability applications.

Product Features

01

Optimized Process Development Through Integrated Development of Cleaning Agents and Cleaning Equipment

Kaken Tech is the only manufacturer in Japan that designs and manufactures both flux cleaning agents and cleaning equipment entirely in-house manufactures both flux cleaning agents and cleaning equipment entirely in-house. Based on the chemical composition of the solder flux, the workpiece size of the circuit boards, and production volume (processing capacity), we propose an error-free, optimal cleaning process that integrates both chemical (agents) and mechanical (equipment) aspects.

02

Continuous Purification via a Distillation Regenerator and Zero Wastewater

A compact distillation regenerator is standard equipment within the system. It continuously distills and recycles a dedicated rinse agent under reduced pressure, recycled, ensuring the final rinse tank consistently maintains the cleanliness level of fresh solution and thoroughly eliminates any residual drying stains. Furthermore, the absence of a water rinse process results in zero wastewater and no waste liquid, maintaining exceptionally low operating costs.

03

A design philosophy that covers everything from mass-production line automation to prototyping

We are capable of designing, developing, and manufacturing a wide range of systems?from the "4-tank, 120 cm wide" ultra-compact manual transport type for prototyping and research departments to large-scale automatic transport types with processing capacities that meet the demands of EMS companies and mass production processes.

Common Challenges

Are you facing these equipment operation and quality control issues when cleaning flux from mass-produced printed circuit boards?

  • The enormous burden of wastewater treatment and drainage management associated with the introduction of water-based semi-water-based cleaning machines: the enormous burden of wastewater treatment and discharge management
    Because these cleaning systems use large amounts of water, they strain the capacity of on-site wastewater treatment facilities and create challenges regarding maintenance efforts and wastewater disposal costs required to meet strict water quality regulations (such as COD and BOD values)
  • The occurrence of drying stains (marks) and defects caused by microscopic residue
    As continuous production proceeds, the detergent concentration in the rinse tank gradually increases, leading to ionic residue and white drying stains (liquid residue) after the PCBs are dried, which threatens the circuit reliability (insulation) of high-density PCBs
  • Limitations in responding to line layout changes or relocation due to equipment being too large and complex
    Batch-type and large-scale in-line washers, such as those manufactured overseas, have a very large footprint, making flexible relocation and repositioning impossible when modifying or expanding factory production lines, which acts as a hindrance to equipment operation
  • Increased complexity in liquid balance management and the significant manual effort required to maintain cleaning quality
    Staff are overwhelmed by the task of managing the balance of liquid concentration and temperature across each slot in multi-tank systems, as well as the frequent replacement of consumables (such as filters), and the maintenance workload required to ensure stable operation of the cleaning equipment is placing a heavy burden on the production floor

Benefits of Adoption by Industry

Automotive Electronic Components
Enhanced management of flux residue on circuit boards, which require long-term reliability.

EMS Companies
Flexible support for high-mix, low-volume production.

Power Devices
Achieves high insulation performance and low ionic residue levels.

Medical Devices
Improves reliability through high-quality cleaning.

Standard Specifications and Equipment Lineup

The MICROCLEANER® flux cleaning machine consists of four tanks: a cleaning tank, a rinse tank, a final rinse tank, and a drying tank.
In addition, the system comes standard with a compact distillation regenerator, which continuously purifies and recycles the rinse solution. This system achieves both high cleaning quality and zero waste liquid, while also keeping operating costs low.

The specifications below are an example of a standard model. We offer custom design and contract manufacturing to meet specific requirements such as workpiece size, cleaning volume, and factory layout space.

Conventional water-based and semi-water-based cleaning machines require large volumes of rinse water, making wastewater treatment facilities and water quality management significant challenges. In contrast, the Micro Cleaner comes standard with a distillation and regeneration system that continuously regenerates the rinse solution, enabling zero-wastewater operation.
