Classification and Advantages of Stencil Cleaning Machines

Stencil cleaning machines are categorized into two primary groups: pneumatic stencil cleaning machines and electric stencil cleaning machines. Newcomers to the SMT industry often wonder about the specific functions of stencil cleaning machines. Essentially, they are industrial tools designed to clean stencils, effectively eliminating residues such as solder paste, red glue, silicon glue, and silver paste post-printing.

Principle of Stencil Cleaning Machines

Pneumatic stencil cleaning machines harness compressed air as their energy source, which negates the reliance on electricity, minimizing the possibility of fire hazards. The method allows for the recycling of cleaning fluids, which not only reduces consumption but also mitigates the risks posed to employees through direct solvent contact. These machines function entirely on compressed air, eliminating any electrical connections and consequently, fire risks. Their user-centered design facilitates a one-key operation, making both cleaning and drying processes seamless. The DEZ-C730 stencil cleaning machine represents a high-performance, fully automatic cleaning solution that relies solely on compressed air from start to finish.

Advantages of Stencil Cleaning Machines

• Zero emissions, promoting an environmentally friendly approach.
• The sealed cleaning method features multiple circulation filtration systems that enable the reuse of cleaning agents. Waste solvents and debris are centrally processed, with solvent recovery machines capable of reclaiming 60-80% of solvents.
• It reduces labor intensity, enhances the visual appeal of the work environment, and minimizes secondary pollution, effectively limiting the worker's exposure to cleaning agents. This notably increases workplace safety.
• These machines contribute to improved printing quality, significantly lowering product rework rates. Post-machine cleaning, no residues are detectable on micro-apertures even under 100x magnification, greatly minimizing printing defects.

Why Use Stencil Cleaning Equipment?

To understand the importance of stencil cleaning equipment, it's essential to recognize the detrimental effects of unclean SMT stencils. Over time, stencils gather substantial solder paste, which can be corrosive. Timely cleaning is crucial, as neglect can result in deformation, damage, and inaccuracies in stencil work. With economic growth and heightened environmental consciousness, businesses find themselves increasingly prioritizing eco-friendliness alongside economic development. Tradition in stencil cleaning often involves manual techniques using cloth strips soaked in cleaning solutions. However, this method is susceptible to improper use of cleaning agents and materials, resulting in waste. Moreover, extended exposure to cleaning agents can pose health risks and worsen air quality in the workplace. In contrast, stencil cleaning machines offer convenience, efficiency, and a lower environmental footprint. Silman Tech stencil cleaning machines provide a fully pneumatic closed operation, where users need only to insert the stencil into the tank, seal the valve, and press the start button to commence the cleaning process. This closed system not only curtails environmental pollution but also significantly cuts down cleaning agent costs for factories.

The information presented above encapsulates the types, essential functions, underlying principles, benefits of stencil cleaning machines, as well as the rationale behind the increasing investments companies are making in these machines.
