After silk screen printing, if the silk screen needs cleaning, the printing ink should be scraped from the image part of the silk screen to the bottom. Currently, the main methods for cleaning silk screens are manual scrubbing with solvent-based cleaning agents and using professional silk screen cleaning machines. Solvent-based cleaning agents are volatile, have…
From manual cleaning to the current pneumatic steel mesh cleaning machine and water-based steel mesh cleaning machine combined with specialized cleaning equipment, steel mesh cleaning has evolved into an industry-oriented, efficient, energy-saving, environmentally friendly, safe, and reliable application direction and development. This application better meets the cleaning needs of manufacturers and the requirements of energy…
The thickness of SMT steel mesh is crucial for SMT manufacturers as it not only affects the SMT pass rate but also directly impacts the reliability and durability of products once they are launched into the market. Below, we present the classification of SMT (PCB) steel mesh thickness accumulated over the years and some tips…
SMT solder paste water-based cleaning agent SMT steel mesh, also known as the stencil, is mainly used to transfer an accurate amount of solder paste to precise locations on the PCB board. The holes on the steel mesh match the areas to be printed on the PCB board. When the steel mesh becomes blocked, it…
Ultrasonic steel mesh cleaning machines have emerged as an alternative cleaning method following manual cleaning of steel meshes. Currently, there are still a few customers using ultrasonic steel mesh cleaning equipment. Compared to other traditional cleaning methods, ultrasonic steel mesh cleaning machines offer several advantages, such as significantly faster cleaning speeds, several times faster than…
Cleaning silk screens efficiently after use is crucial for their longevity and ensuring optimal printing results. Traditionally, manual cleaning methods involve using a type of cleaning agent inside the screen printing machine and then gently wiping the surface layer of the screen with a clean fabric. Nowadays, specialized silk screen cleaning machines are commonly used…
With the rapid development of technological innovation, technology applications are increasingly being utilized in various aspects of our production and daily life. The cleaning methods for fixture cleaning typically include manual cleaning, organic solvent cleaning, vapor-phase cleaning, high-pressure water jet cleaning, and fixture cleaning.

The selection, tension testing, and cleaning methods of SMT stencils are crucial steps in surface mount technology (SMT) assembly, as they directly affect the effectiveness of solder paste printing and consequently impact the final soldering results. To prevent issues such as insufficient solder, bridging, or solder voids, SMT engineers need to rigorously manage stencil-related processes,…
In surface mount technology (SMT) assembly, there are various factors that can impact the final quality, such as the quality of surface mount components, the quality of PCB pads, solder paste, solder paste printing, placement accuracy of SMT machines, and the temperature profile of reflow soldering. Among these, an essential step in SMT assembly is…
Manual cleaning of oil-based ink after screen printing is essential for maintaining the quality of printed industrial products. However, in most screen printing companies, commonly used ink cleaning agents include gasoline, trichloroethylene, acetone, and benzene, also known as washout solutions. These solutions are widely used due to their fast drying rates and low cost, despite…
