For those who don't know the expertise of silicone buttons, how to choose the right and the right process has become a big problem. For example, for those who need silicone buttons for conductive processing, are black particles or conductive inks? Are the characters on the surface of the silicone button carved with a mold, wire mesh or laser? Customers often ask us these questions. Today, I will tell you the difference between the black particles of the silicone button and the conductive ink. How do we choose the right process?
First, the surface of the conductive black particles is textured. The black particles are formed by a general molding similar to the overmolding in the silicone bond forming process, while the conductive ink is relatively smooth and formed by high temperature baking after the conductive ink dots are printed. Second, the black particles are suitable for conductive pillars of the same size and size, while conductive inks are not limited, and some special shapes or sizes and shapes are possible. The conductive resistance of the two is also different. The conductive resistance of the conductive ink is controlled within 500 ohms. If you need the sensitivity of the button, conductive black particles are recommended here, which not only has better stability, but can also be controlled within 100 ohms. It is usually used for some instrumentation silicone buttons to conduct electricity.
All in all, we have a general understanding of the difference between the black particles of the silicone button and the conductive ink, and we hope this will help us.
