Why do UV LED Curing Machine Need to Fullfill Nitrogen (N2)

 Nitrogen UV LED Curing Machine is also a system engineering, integrated with nitrogen protection system, but also integrated with other UV Irradiation Systems of the main body, such as the UV LED light module, drive control, air cooling system and other parts. Because of its higher technology, it is more difficult to manufacture. But compared with the original Wafer-Bonding UV Curing Machine, the LED UV Light Curing Equipment with Nitrogen protection will be better in the ungluing efficiency. The main reason is that the original Wafer-Bonding UV Curing Machine exists in the air between the luminous source and the irradiated object, the oxygen contained in the air will have dust. And when the UV emits ultraviolet light, water vapor and oxygen will be produced between the emitting body and irradiated object, which will reduce the energy of ultraviolet light and thus reduce the UV degumming effect. However, with nitrogen protection, the air is completely isolated so that there is no air between the light source and the object to be cured. So the efficiency of curing effect will be higher and more thorough.

Nitrogen (N2) is a kind of inert gas, is a protective gas, so it is called “nitrogen protection”. Nitrogen is chemically inert. Its molecules are larger than those of oxygen. It is usually a colorless, odorless gas and is generally less dense than air. Nitrogen, which accounts for 78.12% (volume fraction) of the total atmosphere, is the major component of air. Nitrogen reacts poorly with other substances at room temperature. Nitrogen is not easy to expand and contract in heat and cold, and its deformation range is small. Based on nitrogen’s various chemical properties and mechanical properties are better than air, Shenzhen Deshengxing Electronics Co., Ltd. studies the use of nitrogen filled LED UV Light Curing Equipment to discharge oxygen. Shenzhen Deshengxing Electronics Co., Ltd. research of the nitrogen protection in the glue machine refers to the establishment of a relatively closed space in the LED UV Light Curing Machine, the use of nitrogen N2 filled into it, thus greatly reducing the oxygen in the air and water vapor on the UV light source polymerization reaction. Because oxygen and water vapor will be involved in UV LED chemical reaction, loss of UV energy, ozone and affect the chemical reaction of photosensitizer.

The “nitrogen protection system” greatly improves the efficiency of UV degumming and thus greatly improves a series of problems inherent in UV Irradiation Systems of traditional mercury lamp sources. In addition, the speed and uniformity of degumming process are also improved, that is, more kinds of UV films can be degumming without worrying about the effect of degumming.

How To Detach a Wafer From The UV Tape By Using a UV LED Curing Light Systems

 Before the chips scribing, the wafer is fixed to the frame with scribing film. After the scratching process is completed, UV light is used to irradiate the fixed film to make the UV film solidify and harder, so as to reduce the stickiness of the scratching fixed film and facilitate the smooth production of subsequent packaging processes. In other words, the UV tape has a strong adhesive strength and holds the wafer firmly during the wafer grinding process or the wafer cutting process. When ultraviolet LED light radiation, the bonding strength will be reduced. As a result, the wafer or chip can easily peel off the tape after UV LED Light exposure. UV LED Curing Systems Machine solves the degumming process of wafer, glass and ceramic cutting process. It is not only commonly used in semiconductor packaging industry, but also for the use of UV film degumming of semiconductor materials such as optical lens, LED, IC, semiconductor, integrated circuit board and mobile hard disk. The UV curing systems in the prior art mostly uses UV mercury lamp. The light source of UV mercury lamp with high heat emission is easy to be damaged by heat sensitive materials, and its efficiency is low, and its quality standard is difficult to be controlled accurately, so it is not suitable for high precision devices such as chips. Shenzhen Deshengxing Electronics Co., Ltd. adopts the environment-friendly low-temperature LED UV Curing Light Source Systems, easy to complete the UV film de-film process, and does not damage the wafer, greatly meet the production needs.

The details of "What is UV Film? UV Adhesive Principle"

Application :

Suitable for optical lens, LED, IC, semiconductor, integrated circuit board, mobile hard disk and other semiconductor materials, glass filter UV film degumming, UV tape degumming use. UV LED Curing Systems is a kind of UV film and cutting film tape viscosity reduction and viscosity removal of automatic curing equipment. The wafer, glass and other materials can be pasted on 6’’, 8’’ and 12’’ brackets with adhesive dissolving device, which has high efficiency of adhesive dissolving ability and can quickly reduce the stickiness of UV Tape on materials.

What Is UV Film? UV Adhesive Principle

 UV film is a special formula UV coating on coated PET, P0, PVC, EVA film base material surface, is a specially designed for semiconductor chips, special optical glass (wafer of silicon, filter glass), special metal and ceramic substrates and flexible electronics and some small thin fragile parts processing production of fixed, protection, bearing with designed a new type of adhesive products. This material adopts specially polyolefin (PO) and polyester (PET) film as raw material, coated with special adhesive, through dust-free high temperature coating process. UV film with high adhesion, high tensile strength, adaptability, balanced extension and other characteristics, easy to fix some small particles or fragile ultra-thin sheet, so that the material in the grinding, processing and cutting process does not slide, do not fly, no water seepage. At the end of the processing, the UV film after a specific ultraviolet energy irradiation to make the tape lose adhesion, it is easy to separate the product from the tape, and no damage, no residue, very good to meet the semiconductor and optical industry special materials processing process. UV tape can be customized according to customer requirements of various thickness, viscosity and processing customer required shape and size. The principle of UV adhesive is mainly concentrated in the adhesive formula to add a photo-initiator, so that it in a specific value of UV LED light curing, trigger the internal function, making the original high adhesive surface suddenly lose viscosity, so as to meet the requirements of the process.
