Tape and Packaging
1. Tape leader and reel
2. Moisture Resistant Packaging
-The thermal management is the most important thing of the hear dissipation(cooling) performance for the far UV(UVC) LED package.
-The thermal design of the product must be seriously considered even from the beginning stage.
-The co-efficiency between the heat generation and the input power is affected by the thermal resistance of the circuit boards and the density of the LED placements together with other components.
-The deep UVC LED soldered on a metal PCB with a high thermal conductivity. Or Please combine the UVC LED with a metal PCB and a large volume- Heat Sink , a mini(compact / slim)-air or water cooler, etc.
Please design the LED module or system in customer that the temperature of the LED Package does not exceed the maximum junction temperature（Tj）.
2.Human body protection UVC
UVC flip chip emits deep ultraviolet radiation, with extremely high intensity near its surface. This provides rapid disinfection but safety precautions must be observed during assembly and testing. By purchasing the UVC LEDs from the manufacturer, the customer hereby agrees to absolve the manufacture's responsibility of any bodily harm as a result of failure to observe the precautions, warnings and guidelines contained within this Specifications. All assembly workers, observers and bystanders must wear eye and skin protection when the UVC LEDs are energized. Bare eye observation (including through microscopes) and bare-hand handling of a UVC LED in operation is PROHIBITED. UVC light can be easily absorbed, so any oil or other absorbent liquid must NOT be allowed to touch the UVC-LED.
