Photosensitive circuit ink (screen printing type)
Photosensitive circuit ink is used in industrial graphics production. It has high resolution, excellent electroplating and etching resistance, and is suitable for the production of high-precision circuit boards.
1.
Features
This product is in liquid form and can fill defects such as pits and scratches on the surface of the substrate.
The coating is thinner than the dry film, so the pattern resolution is higher than that of the dry film.
Due to the exposure and development method, there will be no shadows, line dog teeth, oil leakage, etc.
Because it is a photopolymerization reaction, it has better bonding, plating resistance, and etching resistance than traditional inks.

Notes
Please operate and store this product under dust-free conditions, temperature ℃, relative humidity %, use yellow light, avoid white light and sunlight.
The exposure energy will change due to the difference in substrate and ink thickness. Please conduct a test to confirm the degree of side erosion before making a determination. The exposure ruler should be controlled at level 1.
After coating, it needs to be exposed and developed within hours. If the humidity in the operating place is high, it needs to be completed within hours. Inner and outer layer line inks, photosensitive solder mask inks, character heat-curing inks, hardware inks, printing inks
