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...

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 Steriliza...

Because LED is a constant current driven electronic component, it is known from the characteristic curve of LED I-V that when the voltage changes slightly, the current passing through the LED will change greatly, which may cause the uneven current flowing into LED. Therefore, LED circuit design is not allowed to use the constant voltage way to drive. If the constant voltage drive is unavoidable, i...

1. The product is sensitive to static electricity and surge voltage, and the chip may be damaged under the impact of static electricity and surge voltage, which will affect the reliability of the product. Therefore, the following anti-static countermeasures should be used in operation. Use antistatic bracelet, conductive clothing, conductive shoes, conductive floor, etc. to remove the charge Groun...

High performance hard organic PCB substrate usually consists of dielectric layer (epoxy resin, glass fiber) and a high purity conductor (copper foil). We evaluate the parameters related to the quality of printed circuit board substrate, mainly including glass transition temperature Tg, thermal expansion coefficient CTE, heat-resistant decomposition time and decomposition temperature Td of substrat...

Some camera module manufacturers used UV lamp irradiation curing before, the time is longer. In addition, the surface temperature of the camera assembly is higher after irradiation, which seriously affects the quality of their products. Therefore, they found us, Shenzhen Deshengxing Electronics Co., Ltd., to conduct special product testing. We knew that, in the production process of the security s...

On December 29, in the expert said, UV LED wind direction jointly held by the expert said 2020 annual meeting · deep ultraviolet LED special summit forum, Mr. Hu Jun, deputy manager of Japan and Asia shared the "280nm sterilization solution and NICHIA UV LED products" keynote speech. Hu Jun, vice manager of NICHIA, pointed out that NICHIA focused on the development of 280nm UVC LED and improve the...

1.UV glue - application in medical supplies One of the driving forces behind the growing use of UV-curable glues is the use of disposable items. UV glue can be used to attach hypodermic needles to syringes and IV tubes, as well as in catheters and medical filters. 2.UV shadowless - in the glass and handicraft, jewelry industry application UV shadowless adhesive with its excellent optical and chemi...
