UV-LED Curing Machine Used For High Performance Electronic Components

 Today, with the continuous development of science and technology, the integration of semiconductor and electronic components is becoming higher and higher, and the requirements for UV LED Curing System Machine used in the packaging process of chips and electronic components are becoming higher and higher. DSXUV, as a UV LED curing system machine manufacture, can meet the needs of precision electronic components adhesive and LEDUV curing, can provide a series of mature products.

Double Side UV LED Curing Light Source System


The following requirements must be met :

1.The strength of UV LED curing machine is to be enough.

Generally speaking, electronic components are mass production. This kind of mass production requires high production efficiency. The higher intensity of the UV LED curing machine and the faster conveyor belt will greatly increase the productivity of a single device. DSXUV LED UV Curing Light Source uses UV LED light chip as the light source, the light intensity is adjustable, can meet the application of a variety of product processes, productivity has several times or even dozens of times of space for improvement.

2.EMC electromagnetic radiation is low:

The higher the integration degree of chips and electronic components is, the higher the sensitivity degree to EMC is, and they can no longer withstand EMC interface emitted by some microwave excited ultraviolet lamps, which makes them have production quality risks. In this regard, DSXUV UV LED Light Curing Equipment as a cold light source, no infrared light, no thermal radiation and EMC interference, more than UV mercury lamp.

3.Heat dissipation of UV LED curing machine is good:

In the long time, high intensity curing work, the heat dissipation of UV LED Curing Lamp Systems is very important. Only the heat dissipation system designed by scientific calculation can guarantee the good operation of UV LED curing system machine.

4.UV LED Curing machine should be small:

High performance components are generally small in size, so the UV LED curing machine is also required to be small in size, which has no impact on other equipment in the production line. And electronic components production workshop environment requirements are very high, such as temperature, humidity and cleanliness. Compared with UV mercury lamp, the integrated design of DSXUV LED UV Light Curing Lamp Machine is more suitable for curing electronic components, and it is flexible and portable. However, UV mercury lamps usually require large distribution cabinet type power supply, fans and conveyor systems, requiring significant adjustments to the factory hardware environment, as well as noise and cleanliness.

About LEDUV Cross-Linked Polyethylene Insulated Cable Equipment

 The technological process of UV Irradiation Cable Crosslinking Equipment is that UV light is used as the radiation source, and the mixed photo-crosslinking polyolefin is extruded and coated on the conductive wire core, and then it immediately enters the special irradiation equipment for melting state optical crosslinking. Photo-crosslinked polyolefin insulated wire and cable products can be obtained after the light irradiation crosslinked insulated wire core is cooled at different temperatures and other subsequent processing.


Cable UV Light Irradiation Crosslinking System Machine only needs to be slightly changed on the original ordinary extrusion production line. The equipment covers a small area, with upper traction, irradiation box, electrical control cabinet, etc., can meet the requirements to produce UV irradiation crosslinking polyethylene wire and cable products. Increase the traction, so that the conductive wire core to maintain a certain tension. Always in the center of the box during operation to ensure the best irradiation effect. The irradiation box adopts uniform configuration and characteristic design of reflective concentrated UV light source, and the electric control system ensures that the ultraviolet intensity and temperature at the center of the irradiation box are in the best working conditions. The efficient optical traction system can quickly trigger polyolefin crosslinking reaction under UV light, so that the equipment can achieve a continuous production speed of tens of meters per minute. The water temperature of hot, warm, and cold is cooled step by step to ensure the stability of the three-dimensional network crosslinking structure.

How to Weld PCB on UV LED Light Beads

 Take NICHIA NWSU333B UV LEDs as an example, the same for other UV LED welding.

Note of Ultraviolet LED Lamp Chip Soldered on PCB

Recommended reflow soldering condition (lead-free solder)

1.This LED is designed to be reflow soldered to a PCB. If dip soldered or hand soldered, NICHIA will not guarantee its reliability.

2.Reflow soldering must not be performed more than twice.

3.When the LEDs are cooled from the peak reflow temperature, ensure that the cooling is performed very gradually to avoid excessive stress on the LED (e.g. causing cracks in the solder joints). ensure that sufficient preliminary verification is performed to ensure that there are no issues with the chosen reflow soldering conditions/process.

4.During reflow soldering, the heat and atmosphere in the reflow oven may cause the optical characteristics to degrade. In particular, reflow soldering performed with an air atmosphere may have a greater negative effect on the optical characteristics than is a nitrogen atmosphere is used. NICHIA recommends using a nitrogen reflow atmosphere.

5.Repairing should not be done after the LEDs have been soldered. It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing.

6.The Die Heat Sink should be soldered to customer PCB. If it is difficult or impossible, use high heat-dissipating adhesive.

7.When soldering, do not apply stress to the LED while the LED is hot.

8.When using a pick and place machine, choose an appropriate nozzle for this product.

9.The soldering pad pattern above is a general recommendation for LEDs to be mounted without issues. If a high degree of precision is required for the chosen application (i.e. high-density mounting), ensure that the soldering pad pattern is optimized.

10.When flux is used, it should be a halogen free flux. Ensure that the manufacturing process is not designed in a manner where the flux will come in contact with the LEDs.

11.Ensure that there are no issues with the type and amount of solder that is being used.

What Are The Advantages Of An Offset Press With UV LED Curing System

Offset printing is one of the main printing methods, with the development of UV LED curing ink and coating technology, UV LED curing system is gradually replacing the traditional UV curing. At present, there are also printing factories for offset printing press equipped with UV LED curing system.

Offset Printing UV LED Curing System Machine


1. Why can UV LED Curing System replace Mercury Lamp?

Mercury lamps have a shorter life, usually about 1000 hours.

Mercury lamp should be preheated before use, and can not restarted immediately after extinguished in the process of use, and then start slowly, affecting production efficiency.

Mercury  lamp spectrum is relatively wide, photoelectric conversion efficiency is slow, power consumption, increase the cost.

Mercury lamps contain toxic substances such as mercury and are not environmentally friendly.

2. What are the advantages of UV LED Curing Systems?

UV LED as a cold light source, no infrared thermal radiation, will not cause thermal effect and deformation, suitable for all kinds of thermal sensitive materials curing.

The service life of UV LED is long, generally about 20000 hours, which is more than ten times of the traditional mercury lamp, reducing the frequency of equipment and the impact on production caused by the replacement of equipment.

Energy saving, power consumption is only 30% of traditional mercury lamp curing machine, saving cost.

Immediately on and off, without preheating before use, the maximum power output can be reached immediately after opening, and the number of switching does not affect the service life.

Suitable LED UV Curing System Machine for Offset Printing can be customized according to the actual needs of customers.

Safe and environmental protection, no mercury, no heavy metal harmful substances, will not produce ozone, safe, environmental protection, energy saving, is a safer and more environmentally friendly alternative to traditional mercury lamp.
