Some customers feel that the curing effect of UV LED curing machine depends on UV LED light source. Although UV LED light source plays a decisive factor in UV glue solidification, it is difficult to achieve good curing effect only by replying on UV LED light source. It is also affected by following important  factors.

1.Cooling system

The heat dissipation system of UV LED Curing Chamber has an important influence on its stable and smooth operation. UV LED Curing Machine with good heat dissipation effect can quickly discharge the heat from UV LED chips. It can not only reduce the temperature of the UV LED Lamp beads, but also reduce the temperature rise of the surface of the object to ensure the stability of the equipment and extend the service life of the UV LED Curing Chamber.

2.The quality of UV LED light beads

The light bead of UV LED Curing System Machine is the core part of the whole UV curing machine. The irradiation head generates an ultraviolet light source through the UV LED light chips. But different quality of UV LED lamp bead, its light effect, energy, stability of light source, light uniformity are very different. The production of UV LED curing equipment by DSXUV, the use of imported lamps beads, the quality of light source will be guaranteed.

3.Control system

The control system of UV LED Curing Light Equipment carries the circuit operation control of the whole set of UV LED curing machine, providing technical guarantee for the maneuverability and safety of the equipment. The light source controller produced and developed by DSXUV can set power of light source, irradiation time and control mode according to the actual working conditions. It also can be connected with external pedal control switch or RS232 serial port.

4.Customized UV LED curing light source comes to DSXUV

Whether Nitrogen Filled UV LED Curing Box Can Be Used For Curing UV Glue On Circuit Board

 Nitrogen-filled UV LED Curing Box can not only meet the curing of conventional UV glue on the circuit board, but also can be used for some special types of UV glue. Like some UV glue internal add oxygen inhibitor, in the ultraviolet light source after the irradiation, the glue internal can be completed fast curing, but the UV glue surface is difficult to dry. These require the provision of an oxygen-free curing environment. DSXUV special developed a UV LED Curing Oven for UV curing in the absence of oxygen environment, by vacuuming the air in the UV LED Curing Chamber, set up a nitrogen protection system, you can solve these problem.

What Are The Advantages Of Nitrogen UV LED Curing Systems

 Nitrogen UV LED curing oven, also known as inert gas UV curing box, is a new type of UV LED light source, is through the external nitrogen to create a clean and constant temperature environment without oxygen. The nitrogen filled UV LED Curing Chamber developed by DSXUV has a great difference from ordinary UV curing chamber in its internal circulating air duct performance and curing structure. Nitrogen UV LED curing oven is equipped with nitrogen inlet and outlet device, and nitrogen flow meter can more accurately control the flow of nitrogen into the box, with a quick plug and pull charging interface, convenient for nitrogen into, at the same time through the control of nitrogen flow, so that nitrogen can be fully used.

How to Weld PCB on UV LED Light Beads

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

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.
