Flexible pcbs are manufactured on a substrate of polyimide, and are free to bend, which Allows the installation of such boards in places, as well as use them as a flexible Connector. Flexible boards allow increased density mounting of electronic devices, Effectively using 3-d space. Basic materials: polyimide Thickness: 12.5 - 200 microns Surface finish: tin immersion and gold flash

LED light.

For the Mosquito killer Led Bulb Light, is a 900 lumen bulb that doubles as an insect killer. The light features a blue UV LED which attracts insects into a Mosquito Killer grid.And the Mosquito Killer grid uses only 1W of electricity, while the light itself uses a meager 9W – and both can be used independently.They are used at home and outdoor. A brush is provided to clean off insects once the bulb switched-off.Compare to other traditional mosquito killer, this bulb has no chemicals, no sprays and hence no fumes to our life. • 2nd generation 2-in-1 LED LIGHT Bulb Plus LED Mosquito Killer Bulb • Wattage: 10W • Blue UV light • Lumen: 900-1000lm • Color Temperature (CCT): 6500K • Input Voltage: AC 90-130V & 220v-240V • With CE and ROHS Operation: Step1: Switch it on,both lighting +killing are on. Step2: Switch on again,light off,only killing on. Step3: Switch on again,killing off,only light on. Step4: Switch off, both off.
