Stencil cleaning machines are divided into two main categories: pneumatic stencil cleaning machines and electric stencil cleaning machines. Many newcomers to the SMT industry may wonder what stencil cleaning machines are used for. In fact, stencil cleaning machines are industrial cleaning equipment used to clean stencils. Specifically, they are used to remove residues such as solder paste, red glue, silicon glue, and silver paste from stencils after printing.

Principle of Stencil Cleaning Machines: Pneumatic stencil cleaning machines utilize compressed air as the energy source, eliminating the need for electricity and any fire hazards. They recycle cleaning fluid, resulting in low consumption and avoiding potential harm to employees from direct contact with solvents. These machines operate entirely on compressed air, without requiring any electrical connection, thereby eliminating the risk of fire. They feature user-friendly design with one-key operation, making cleaning and drying effortless. The DEZ-C730 stencil cleaning machine is a high-performance pneumatic fully automatic cleaning equipment that operates entirely on compressed air from cleaning to drying.

Advantages of Stencil Cleaning Machines:

1. Zero emissions and environmentally friendly.
2. Sealed cleaning method with multiple circulation filtration systems allows for reuse of cleaning agents. Waste solvents and debris are centrally processed, and solvent recovery machines can recover 60-80% of solvents.
3. Reduces labor intensity, improves work environment aesthetics, and minimizes secondary pollution, significantly reducing the chances of cleaning agents coming into contact with or being inhaled by workers. Increases labor safety coefficient.
4. Improves printing quality and reduces product rework rates. After machine cleaning, no residues are observed on micro-apertures even under 100x magnification, significantly reducing instances of printing defects.

Why Use Stencil Cleaning Equipment? First, let&#;s understand the impact of unclean SMT stencils. Over time, stencils accumulate a lot of solder paste on their surface, which is corrosive. Failure to clean them in a timely manner can lead to deformation, damage, and reduced accuracy of the stencils. With economic development and increased environmental awareness, companies are increasingly valuing environmental protection while developing the economy. Traditional stencil cleaning is done manually, using cloth strips soaked in cleaning solution for scrubbing. However, this method often leads to improper usage of cleaning agents and cloth, resulting in wastage. Moreover, prolonged exposure to cleaning agents poses health risks to employees, and solvent exposure in the workplace can lead to air pollution. Compared to manual methods, stencil cleaning equipment offers convenience, efficiency, and reduced environmental impact. Silman Tech stencil cleaning machines feature fully pneumatic closed operation, requiring only stencil insertion into the cleaning tank, valve closure, and pressing the start button to initiate the cleaning process. The closed cleaning system reduces environmental pollution, while the recycling of cleaning agents significantly reduces costs for factories.

The above summarizes the types, basic functions, principles, advantages of stencil cleaning machines, and reasons why more and more companies are purchasing stencil cleaning machines.
