What are the applications of ultraviolet light?

Ultraviolet light is very common, and in the process of use, people should be aware of the existence of ultraviolet light, but also should understand where its application.  The role of ultraviolet in many aspects, and every aspect of the application in life is very big, so in order to let you clearly understand ultraviolet, better use of ultraviolet, the next specific introduction of the role of ultraviolet and ultraviolet applications.  What are the applications of ultraviolet light?

1, microelectronics industry -UV light curing application:  Mobile phone components assembly (camera, headphones, microphone, shell, LCD module, touch screen coating, etc.), hard disk magnetic head assembly (gold wire fixation, bearing, coil, chip bonding, etc.), DVD/digital camera, lens, lens glue, circuit board reinforcement), motor and components assembly (wire, coil is fixed, the coil end is fixed, PTC/NTC component adhesive,  Transformer core protection), semiconductor chips (anti-moisture protective coating, wafer mask, wafer contamination inspection, UV tape exposure, wafer polishing inspection), sensor production (gas sensor, photoelectric sensor, optical fiber sensor, photoelectric encoder, etc.)  

2, PCB industry LEDUV light curing application: components (capacitance, inductance, various plug-ins, screws, chips, etc.) fixed, moisture-proof sealing and core circuit, chip protection, anti-oxidation coating protection, circuit board protection (Angle) coating, ground wire, flying wire, coil fixing, wave soldering through hole mask.  

3, light resin hardening application: uv curing resin is mainly composed of oligomers, crosslinking agent, diluent, photosensitizer and other specific additives.  It is the use of uv light irradiation of polymer resin, so that the cross-linking reaction and instant curing.  Under the irradiation of UVLED UV light curing machine, the curing time of UV-curable resin does not need 10 seconds at all, basically 1.2 seconds can cure, much faster than the traditional UV mercury lamp curing machine.  At the same time the heat aspect is also more ideal than UV mercury lamp.  By mixing different components of uV-curable resin, products can be prepared to meet different requirements and uses.  At present, uv-curable resin is mainly used for wood floor coating, plastic coating, such as PVC decorative sheet, photosensitive ink coating (such as plastic bag printing), electronic products (tag and circuit board printing, printing glaze (such as paper, poker glazing), metal parts, such as motorcycle parts), optical fiber coating, coating photoresist and precision parts and components of coating, etc.
