1. What are the characteristics of nylon mesh screen?
Nylon mesh is made of chemically synthetic fibers and belongs to the polyamide family. Nylon mesh has high strength, abrasion resistance, chemical resistance, water resistance, and elasticity are all better. Because the wire diameter is uniform and the surface is smooth, the ink passability is also excellent. The disadvantage is that the stretchability of the nylon mesh is large. This kind of screen has a reduced tension after stretching for a period of time, which causes the screen plate to become slack and the accuracy to decrease. Therefore, it is not suitable to print circuit boards with high dimensional accuracy.
2. What are the characteristics of polyester mesh screen?
Polyester mesh is also made of chemically synthetic fibers and belongs to the polyester family. Polyester mesh screen has the advantages of solvent resistance, high temperature resistance, water resistance, and chemical resistance. Polyester mesh screen has stable physical properties and small stretchability when external pressure is large. The disadvantage is the poor wear resistance compared to nylon mesh. In addition to the advantages of nylon screen printing, polyester screens are also suitable for printed circuit boards that require high dimensional accuracy.
3. What are the characteristics of stainless steel mesh screen?
Stainless steel mesh is made of stainless steel. Stainless steel wire mesh is characterized by good wear resistance, high strength, and low mechanical elongation. Due to the fine wire diameter, the ink's passing performance is stable and its dimensional accuracy is stable. The lack of flexibility is good, the price is more expensive. After the screen is stretched, it cannot be restored to its original shape. Stainless steel screens are suitable for high-precision printing such as circuit boards and integrated circuits.
