Many friends often ask me, "After work, I don't know what to use to clean the net plate. No matter what I do, I just can't clean it thoroughly. What would be the best way to do it? Let's talk about it this time."
At present, the two main materials for screen printing plates are stainless steel mesh and polyester fiber mesh.
Currently, based on the material system, the slurry can be divided into two major categories: oil-based and water-based. The oil-based type uses various solvents as the dissolving agent, dissolves the resin, and then adds functional materials to form the slurry.
For oily electronic pastes, the commonly used cleaning solutions include industrial alcohol, acetone, and 718. Generally, the net plates can be cleaned thoroughly with alcohol. Alcohol has almost no smell and poses less harm to the human body. However, its cleaning ability is weaker than that of acetone, and acetone has a stronger smell.
For mesh plates with very small mesh sizes, or when the slurry has been left on the mesh plate for a long time and has dried or semi-dried, alcohol and acetone may not be able to clean it thoroughly. In such cases, a more powerful mesh cleaning solution - 718 is needed. It is a mixed solvent composed of surfactants, organic solvents and additives. It is a colorless transparent liquid, commonly known as mesh cleaning solution. It has strong cleaning power, but it has a significant irritation to the respiratory tract. Please pay attention to labor protection when using it.
Water-based pastes are easier to clean. They can be washed clean with just tap water. However, please be mindful of environmental protection and do not directly discharge them into the sewer.
What material should be chosen for the screen printing plate - polyester fiber screen or stainless steel screen? How many mesh sizes are appropriate? What size should the frame be? Next time we'll talk about it.
Why is the resistance of the printed resist paste larger at the periphery and smaller in the middle after it is fired?
Why does the corneal membrane turn black and dark?
Why are there various issues around the periphery of the same sintered plate? Such as blackening, silver spots, and increased resistance?
