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.

UV LED Curing Equipment Used In Optical Lens Bonding

 

In the field of electronic optics, the use of UV glue for the gluing of optical lenses has been very common. 

When curing UV glue, many manufacturers will choose to use UV LED curing machine instead of 

traditional UV mercury lamp for curing, why? One of the key factors is that the ultraviolet light source 

produced by the UV LED Curing Systems is a single band, and belongs to the “cold light source”, 

no thermal radiation damage and other advantages. In contrast to the traditional UV mercury lamp, 

the use of UV LED Ultraviolet Light can effectively prevent the deformation of the lens when it fits.

The UV LED curing equipment has been mature used in all kinds of gluing requirements of UV glue for 

optical lenses. For the problem of poor curing effect caused by glue leakage at the edge of the lens, the 

UV LED curing function developed and produced by Deshengxing Technology effectively solves the 

problem of bubbles generated in the gluing process of optical lenses or the problem that the lens edge 

solidifies and does not dry.

The type of optical lens UV curing machine can be divided into UV LED Spot Light Source, Large Area 

UV LED Surface Curing Light Source, and Linear UV LED Curing Light Source according to the cured 

area. For example, a 200*100mm UV LED Curing Systems is supplied to a manufacturer of high 

precision optical lenses in Guangdong, China. The first test result is OK. After some testing, the 

irradiation area, illumination intensity, curing time of the customized 100*200mm UV LED Curing 

Systems are very in line with the customer’s requirements. The customer promptly placed an order 

for two UV LED Curing machine after we quoted a reasonable price.

What Applications Does UV 365nm Curing Bonding Use?

 UV glue bonding makes economic automatic assemble of medical instruments easier. Now, advanced LED UV Curing Light Source can solidify solvent-free UV glue in seconds, and the dispensing system is an effective and economical way to form a consistent and repeatable adhesive during the assembly process of the medical devices. The optimization and control of Spot LED UV Solidification light source is very important for the manufacture of reliable medical devices. Using UV curing glue provides many advantages, such as lower energy requirements, saving curing time and location, improved productivity, and easier automation. UV glue is generally used to bond and seal medical instruments, these medical instruments need very high quality and the best reliability. UV glue curing is typically used in medical device assembly where bonding is required, 1) to different materials (or mechanical properties are different), 2) the materials are not thick enough to use the soldering method, 3) pre-produce sub-parts.

Bio-Safety Of 222nm Irradiation Lamp For Sterilization

 Because the UV sterilizing lamp currently in use has a wavelength of 254nm, it can cause strong damage to the human body, so it can only used in enclosed space. Various universities have published papers showing that 222nm does no damage to the DNA of epidermal cells and only hits the cornea. In other wards, the new sterilization device can be used in the general environment.

Ultraviolet Sterilization Principle

The DNA of bacterial and viral can be irradiated with 100 to 300nm ultraviolet light, and the DNA will lose its ability to replicate.

Safety of 222nm Excimer Lamp for Sterilization

The ultraviolet disinfection lamp with the wavelength of 254nm has been used for a long time, which can penetrate through the human body to the deep layer of the skin and have strong harm to the human body, so it can only be used in a confined space environment.

The wavelength of 222nm has no effect on human body, and can effectively inhibit bacteria and viruses, so it is a safe light source.

Therefore, it can be used in the ordinary living environment, and there is no restriction on the placement of all places.
