High-performance electronic components UV curing equipment-FUWO UV-LED light-curing device

With the development of technology, semiconductors, electronic components are becoming more integrated, used for chip / electronic component packaging process UV-LED light curing equipment requirements are also increasing.

UV light curing strength enough: high volume production, the production efficiency is also high, high intensity and fast UV curing conveyor belt, will greatly enhance the production capacity of a single device. FUWO UV-LED light curing device using UV-LED as a light source, a variety of products to meet the application process, the production capacity several times or even several times with room for improvement.

EMC electromagnetic radiation must be low: Chip / higher degree of integration of electronic components, the higher sensitivity for EMC, has been unable to withstand some of the microwave excitation of UV light emitted EMC interference, there is a production quality problems. FUWO UV-LED with LED cold light source, no infrared light, no heat radiation and EMC interference.

FUWO UV-LED light curing device body temperature is low: light intensity increase, the need to increase the lamp power. Most UV conveyor adopt such 3KW-10KW ranging from UV lamp to produce a relatively high intensity of UVA. However, for high-performance electronic components, the temperature requirements are very strict, 3KW-10KW power consumption, most of conversion to heat causes the temperature to enhance the case, generally 80-200 degrees, many plastic packaging has not withstand. FUWO UV-LED spot light line source surface light source and power supply design, dozens of W, can produce 9600mw/cm2 of UVA light intensity (in parabolic reflector hood), in conjunction with the Sino-Japanese joint research and development technology has a unique automatic cooling system, control cabinets temperature, generally the ambient temperature can be controlled at 5 degrees or less.

Ozone and safety protection: UV curing machine conveyor major safety hazard for the ozone generation and UV protection, a number of large power UV conveyor may want to consider the safety of the power box. UV light, especially when the short-wavelength ultraviolet light, such as 250nm, will stimulate oxygen to produce ozone, the greater the power of the lamp, resulting in higher ozone general. Usually equipped with an exhaust port, the connection factory exhaust system. FUWO UV-LED light curing device using LED cold light source produces no ozone, green, very safe for the operator.

Small size, the notebook size, had no effect on other devices: high-performance components in general smaller, but the production workshop environment requirements are very high, such as temperature, humidity and cleanliness. Light source and power supply are all integrated together in part, conveyor belts do not require additional equipment, the entire device digital, concise. Small size, low power requirements, basic does not have an impact on other devices. The UV conveyor usually need much power distribution cabinet, fan and conveyor systems, the need for factory hardware environment to make a large adjustment in order to use, while the noise and cleanliness also have a greater impact.

FUWO UV-LED light curing device system, it is efficient features, has been in INTEL (Centrino processor package), Honeywell and other famous companies to be successful with.

Mini speaker / receiver from the solvent to UV adhesive glue cost-effective solution for upgrading

The traditional micro-speaker / receiver manufacturer in the adhesive and the coil diaphragm and the lead fixed in a large amount of a solvent adhesive. In some applications, the heat generated by high-frequency vibration, the operation solvent glue operating temperature range, diaphragm and coil bonding loose, resulting in noise, seriously affecting the quality of the performance of miniature acoustic components. Currently in high-end miniature acoustic components commonly used UV adhesive bonding, as PHILIPS, Pioneer, while the international medium-sized enterprises looking to upgrade many of the current production process to the UV adhesive on.

Compared with the traditional glue, UV glue and ultraviolet light source / conveyor equipment prices hinder UV bonding process in international development. For glue, because dispensing very small, most of the manufacturers also accepted. UV curing equipment matching belt allows a one-time purchase cost deterred many small and medium enterprises.

UV sealant suitable sensor compact UV light

UV sealant (UV SEALAND) in the sensor industry (such as gas sensors, photoelectric sensors, photoelectric encoder, optical fiber sensors, etc.) have a very wide range of applications. LOCTITE, DELO, DYMAX, HERNON, FOTOPOLYMER others have similar glue supply. But how to choose a suitable UV LED light source it?

Sensor features production needs:

1. Small components and small batch production: In most cases a small selection curing equipment to meet production needs, while there are many types of products to meet the flexible configuration.
2. Low temperature curing: In most cases, the sensor, or liquid containing a variety of plastic parts, the curing process temperature will seriously affect the life of the device.

Small liquid crystal display (LCD or LED) UV curing solutions

Mobile phones, MP3/MP4, mobile DVD, mobile TV and other popular consumer electronics, where a small LCD screen (6 inches less) demand continues to increase, the appropriate choice of UV light curing equipment for LCD sticky border Next, many technicians consider.

And a large LCD panel production was significantly different, a large LCD screen usually requires wide light curing equipment, often using high-power, a dozen or dozens KW KW of large curing machine, would be more efficient, but the small LCD this screen also need UV curing equipment it? obviously not.

Here we discuss the development stage of the LCD device and the mass production of the device solution.

Research and development stage, is used to determine the associated glue, glue, UV curing time and intensity (or UV energy) and other parameters, one experimental UV-LED curing equipment, you can save your lab space and offers flexible settings approach will greatly save your lab time, while maximizing protection of the safety of personnel. FUWO UV-LED light curing device is a sophisticated digital UV light source can be miniaturized composition, powerful UV-LED curing light, easy to do a variety of experimental conditions tested.

2) Automatic program switch and internal cooling chips: Let curing component temperatures low
3) Standard configuration lock function: to provide a 360-degree UV protection, safer
4) Small size / weight / stability and durability: you can put a small test table


Production stage, we mainly consider the production efficiency and maintenance cost. FUWO UV-LED light curing device line source surface light source: low power consumption, high luminous efficiency, low temperature, micro-structure and other characteristics, the effective radiation area of 30 - 600 * 2000mm, ideal for curing some small LCD panel. tie 1-4 sets of UV light source, you can set 9600mw/cm2 UV energy to meet the high-volume production and low demand on the production environment, there is no interference to other test equipment .

For this application, I recommend using FUWO UV-LED 420nm visible light curing device with enhanced LED, mainly concentrated in the spectrum of 395-445nm, can be completed in 5-20 seconds uv light curing. Power consumption less than 60W, temperature no more than 5 degrees, the perfect solution to the actual problem.
