Editor to share with you the application of three ultraviolet rays, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's learn about it!

UV applications include: 1, UV curing applications in the microelectronics industry; 2, PCB light curing applications in the LEDUV industry; 3, optical resin hardening applications.

The applications of ultraviolet rays are:

1. Microelectronics industry-UV light-curing applications: mobile phone component assembly (camera lens, handset, microphone, housing, liquid crystal module, touch screen coating, etc.), hard disk head assembly (gold wire fixation, bearing, coil, chip bonding, etc.), DVD/ digital camera (lens, lens bonding, circuit board reinforcement), motor and component assembly (wire, coil fixed, coil end fixed, PTC/NTC component bonding, etc.) Protection transformer core), semiconductor chip (moisture protection coating, crystal element mask, crystal element contamination inspection, UV tape exposure, crystal element polishing inspection), sensor production (gas sensor, photoelectric sensor, optical fiber sensor, photoelectric encoder, etc.)

2, PCB industry LEDUV light curing applications: components (capacitors, inductors, various plug-ins, screws, chips, etc.) fixed, moistureproof filling and core circuit, chip protection, anti-oxidation coating protection, circuit board protection (angle) coating, ground wire, flying wire, coil fixed, wave soldering through hole mask.

3. Application of photoresin hardening: UV-curable resin is mainly composed of oligomers, cross-linking agents, diluents, photosensitizers and other specific auxiliaries. It irradiates the polymer resin with ultraviolet light to make it cross-linked and solidify instantly. Under the irradiation of UVLED UV curing machine, the curing time of UV curing resin does not need as long as 10 seconds, basically 1.2 seconds can be cured, which is much faster than the traditional UV mercury light curing machine. At the same time, the heat is also better than that of UV mercury lamp. Through the different blending of the components of UV-curable resin, the products that can meet different requirements and uses can be prepared. At present, UV-curable resin is mainly used for wood floor coating, plastic coating (such as PVC decorative board), photosensitive ink (such as printing of plastic bags), electronic products coating (such as marking and circuit board printing), printing polishing (such as paper, playing card glazing), metal parts (such as motorcycle parts) coating, optical fiber coating, photoresist and precision parts coating, etc.

The above is all the contents of this article "the Application of three Ultraviolet rays". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
