What are the issues that need attention when etching processing of optical inks？

The problems that should be paid attention to in the process of using the photosensitive ink during etching are mainly the following points:

   1. Drying temperature and time: In order to achieve the effect of the coating, you will add a certain amount of solvents to the light ink before applying to adjust the viscosity. After the surface, it is necessary to clean it up and clear the diluent in the ink by circulating hot air ovens and hot air ducts. Mastering the drying temperature and drying time becomes extremely important.

   2. Use the correct light sensing source: UV light is the external condition of ink imaging. If the wavelength of the light source is not the range of ultraviolet light, the sensitivity ink does not absorb, and ultraviolet light can cause chemical response to the sensor ink. The glass will absorb ultraviolet light below 300nm, so it needs to use a strong light source of more than 300nm.

   3. The humidity and time of the shadow: The sensitivity of the sensitivity is mainly the resin ingredient, and the resin is hydrophilic. It is better to dissolve when the alkaline aquatic solution. Solk. During the development process, the temperature has a greater impact on the speed of ink dissolution, so it will be much faster to increase the concentration of seeing the see-through temperature than the sodium carbonate aqueous solution.

Metal etching is a part that uses a chemical solution to corrode the metal. The part that does not require corrosion through the sensor ink or protective film protects the part that does not need to be corroded, and the carved part is etched into a filter, logo, text, etc. The difficulty of processing the processing of metal etching is too much in the inconvenience. There are mainly the following points：

1. The metal material required for metal etching processing must be good. Do not choose materials with more impurities, but to etch a special metal material;

   
   

  2. The chemical solution formula of metal etching should be stable, and different metal materials are equipped with different solution formulas;

  3. The process control of various processes in metal etching is also one of the difficulties. Controlling the metal etching processing is an important specification for etching products.
