Circuit board whether single-sided PCB board or double-sided circuit board or multi-layer circuit board will do ink, the difference is that single-sided circuit board only one side of the circuit board

ink, but double-sided circuit board or multi-layer circuit board will have two sides of the ink, that is, we often say TOP and BOM two-layer ink, this is everyone knows and has seen.

Today, Shenzhen Shuostrong Electronics will tell you the difference between these two inks, the so-called photosensitive ink is the ink has a strong light reflectivity, with the naked eye in the light

like a mirror can reflect the light, the so-called “matte ink” is a very weak light reflectivity, with the naked eye there is a fog feeling of ink, less reflective in the assembly of parts, The operational

aspects of the assembly may be advantageous. In addition, in some research literature, matte inks have the phenomenon of repelling stick because of the micro-granular structure on the surface. The

nature of this aspect, in terms of nano technology, is that because the surface has a nano structure, it can be resistant to adhesion and good cleaning, similar to the surface of the lotus leaf has water

resistance. Generally, matte inks are used more by European customers, but there are fewer users in Asia.

Now we know the difference between the two inks on the circuit board, and can also choose what kind of ink to use in practical applications to produce the circuit board, but matte ink is more

expensive than photosensitive ink, which also needs to be noted, because in this competitive market, cost is an important standard for product sales. Therefore, when we produce the circuit board,

we need to choose the process and ink according to the need and the cost of the circuit board!
