Description

A kind of high uniformity LED parallel exposing machine light-source systems
Technical field
The present invention relates to optical system and ultraviolet LED exposure light source technical field, more particularly to a kind of high uniformity LED Directional light ultraviolet exposure machine light-source system.
Background technology
In the micro Process such as microelectronics, micro-optics, wiring board field, ultraviolet parallel exposing machine is to realize that high accuracy processing is multiple The important equipment of system.Figure equidimension on mask plate is transferred to mask by parallel exposing machine by directional light photoetching process On photoresistance below version, then it is further diverted into again by corroding or etching on substrate.
Parallel exposing machine generally use ultraviolet is as lighting source.Mercury lamp is used in traditional parallel exposing machine Light source, mercury lamp have high pressure, high temperature and the shortcomings that containing poisonous mercury.The life-span of mercury lamp generally only has or so 1000 hours, because This, after 1-2 months, then needs to replace primary source, maintenance cost is high.The energy consumption of ultraviolet mercury lamp is larger, use cost It is high.There was only about 20% energy production ultraviolet in its input energy, and it is the visible energy to have 20%, 40% is heat, Er Qieqi Luminescence band is more;Meanwhile the switch life of mercury lamp is limited, just light intensity keeps stable after a period of time of turning on light, in order to keep it Light stability, exposure also keeps state of turning on light in time in use, further increases its energy consumption.Mercury lamp is due to shortwave The radiation of long ultraviolet can have the ozone of harmfulness.2013, global more than 140 individual countries and regions were reached common understanding, and Presided over and signed by United Nations Environment Programme《Minamata pact》, limit control and discharge capacity plan of the every profession and trade to mercury composition.Using New energy-conserving and environment-protective ultraviolet source substitutes traditional UV Exposing Lamp, and oneself is imperative.Ultraviolet LED (the pole of luminescence-utraviolet two Pipe) it is fast-developing in recent years, compared with mercury lamp, have long lifespan, energy-conservation, spectral line it is narrow, it is not mercurous, do not produce ozone, moment opens Close, the advantage such as stability is good, attract attention in ultraviolet exposure machine is applied and be progressively applied.
Light ray parallel degree and the uv energy uniformity are two most important technical indicators of uv-exposure light source and exposure machine. In effective exposure area of exposure machine, the depth of parallelism of ultraviolet, energy uniformity etc. determine the precision and uniformity of exposure. The depth of parallelism is better, lines that more can be thinner in transfer mask version, obtains higher exposure accuracy.It is because optical exposure illuminates Irradiation level of uniting is uneven, causes line weight uneven, the resolving power in entire plate is inconsistent, or has the hair of phenomena such as broken string Raw, this does not allow in the production process of PCB or liquid crystal display;The uv energy uniformity is higher conversely speaking, then Line weight is more uniform.
Because single ultraviolet LED lamp bead luminous power is very low, to reach with the power density needed for large area exposure, it is necessary to Multiple lamp beads work simultaneously.Simultaneously as the lighting angle of LED lamp bead is wider, its luminous often center intensity is higher, more toward two Side luminous intensity is lower.When use optical design is lighted and is changed into directional light, the uniformity of irradiation intensity is often difficult to Ensure, it is necessary to particularly design.
CN105301910A discloses a kind of ultraviolet LED light source structure and parallel exposing machine.Utilize the portion of mercury lamp light source Path-splitting.Its technical method is using during upgrading in existing exposure machine, but the characteristics of do not give full play to LED, the arrangement of LED light face More concentrate, cooling requirements are higher, and light intensity is also by larger restriction.
CN104749889A discloses a kind of ultraviolet LED photohead, and its is simple in construction, and cost is low.But characteristics of optical path is based on, The region area that the technology can provide uniform parallel light is relatively limited.
CN103513518B discloses a kind of ultraviolet LED exposure machine optical exposure illumination system and ultraviolet LED exposure machine. The technology is realized directional light by collimation lens, is passed through square using the collimation ultraviolet LED light source for being arranged in order multirow equidistant arrangement The battle array arrangement position relatively low to the intensity of light source compensates, so as to improve the uniformity of exposure.The technology can realize large area Directional light.But when improving due to the depth of parallelism, lighting angle narrows, uniformity compensation is more difficult, and the uniformity can decline.Therefore need The technical scheme of the uniformity and the depth of parallelism is preferably taken into account, to adapt to require higher application.
Further, since LED lamp bead glow peak is narrow, wavelength is single, and prior art is to different ink and photoresistance adaptability It is bad.
