SMT stencils are commonly used in surface mount technology for solder paste on printed circuit boards. According to different materials and structures, SMT stencils can be divided into the following categories:
In SMT production and processing, you will often hear SMT stencil once, what is SMT stencil?It is a commonly used tool in surface mount technology, mainly used for solder paste on printed circuit boards, this article will introduce several commonly used SMT stencil materials.
Commonly used SMT steel mesh materials: stainless steel mesh, chrome-plated steel mesh and titanium alloy mesh. Let's talk about it briefly:
1.Stainless steel mesh: It has excellent corrosion resistance and wear resistance, is suitable for most SMT printing processes, and is one of the most commonly used SMT steel mesh.
2.Chrome-plated steel mesh: It has better wear resistance and corrosion resistance, and is suitable for high-precision and high-speed printing processes.
3.Titanium alloy mesh: with higher hardness and strength, suitable for high-demand printing processes.
Manual cleaning of SMT stencil steps:
Use a scraper to scrape off the remaining solder paste;
Soak the stencil with detergent or stain remover to remove stains and grease;
Rinse well with water to ensure that the detergent and stain remover are completely removed;(Avoid using hard objects or brushes to scratch the stencil to avoid damaging the stencil surface).
Dry with a dryer or let it run naturally.
The above is the introduction of JTB to the commonly used SMT stencil materials, I hope it will be helpful to you.
