SMT stencils are commonly used tools in surface mount technology for applying solder paste onto printed circuit boards. They can be classified into the following types based on different materials and structures:
- Stainless steel stencil: Stainless steel stencils are the most commonly used in SMT applications. They offer excellent corrosion resistance and durability, suitable for most SMT printing processes.
- Chrome-plated steel stencil: Chrome-plated steel stencils provide better wear resistance and corrosion resistance, making them suitable for high-precision and high-speed printing processes.
- Titanium alloy stencil: Titanium alloy stencils offer higher hardness and strength, making them suitable for demanding printing processes.
The cleaning method for SMT stencils is as follows:
Manual cleaning:
- Scrape off residual solder paste with a scraper.
- Soak the stencil in a cleaning agent or degreaser to remove stains and grease.
- Rinse thoroughly with water to ensure complete removal of the cleaning agent or degreaser.
- Dry using a dryer or air dry naturally.
It is important to avoid using hard objects or brushes to scrub the stencil during cleaning to prevent damage to the stencil surface. Additionally, use appropriate cleaning agents or degreasers to avoid corrosion or damage to the stencil.
Professional equipment cleaning: You can use the Silman Tech Stencil Cleaning Machine DEZ-C730 for cleaning. This equipment operates entirely on compressed air, eliminating the risk of fire hazards. It features user-friendly design and one-touch operation for easy cleaning and drying. It is a high-performance cleaning device operated by pneumatic pressure, allowing for low consumption of cleaning fluid.
