We are making a footprint for the L1C1-RED1000000000 led led Datasheet: The recommended land pattern on page 27 of the datasheet shows the pcb pads being smaller than the actual led?s own pads. (leds own pads shown on page 25) -Presumably this is to stop the led from sliding (...)
Hello, Attached is a 110mm x 46mm x 1.5mm Aluminium led pcb. Would the leds ever be layed out on this board by hand (tweezers), prior to putting through the solder oven, or is it always done by pick and pace machines? (in UK/Europe/USA) If they are layed out by hand then we would put all the leds with cathode facing (...)
nm is unit of light wavelength or light "color", not related to "distance". Down to 380 nm is still visible light. Shorter wavelength led is difficult to produce and thus more expensive. Preference for a specific wavelength depends completely on the application. What's your application for UV leds?

An essential information, not provided: Are you driving the led array with a continous current or pulsed ?
At the same time I need to run the program to on and off the led of the Matrix by looking at 3D view Simulations are usually made on schematic, not extended to the pcb view. I'm not sure if you'll find some design tool with that functionality.
key switching, led on/off ... 7 segment indicator Falstad's simulator is animated and interactive. It does the above actions. Its analysis tools are less sophisticated than the other packages you mention. Free to download and use:
and the person who gave me those pictures don't have the schematic of that pcb, is it possible form me to code these led's? The whole board seems quite simple, therefore if you start from scratch, drawing unknown devices as empty boxes, would be easy to us deduce their function as well its specifications.
Hi Friends, I have a Segmented LCD with 8 digits and am wanting to interface it with an MSP430 eval. board. On opening it up, I was left with a glass pane terminating as a connector. So, There is no scope for soldering. I ended up in thinking for alternatives. That's when I got a series of problems. One after the other. 1)leds consume a lot
121343Hello friends, We produce single side pcb with CEM-1 laminate for led lights in really competetive price ,details: Laminate: CEM-1, KB 5150 Solder mask: white, Taiyo PSR4000 W3 Surface treatment: OSP or HASL Volume order: >=100sqm Delivery date: 2-3weeks Pr
thanks, I reckon its easily 10 billion, , yes , I also meant to include led driver, fluorescent drivers etc.
The losses due to light emission should be negligible, and the power consumption of the led can be took solely on the current across its terminals against its drop voltage. Even assuming that the OP is referring to a continuous operation ( not pulsed ), the power density over this sufrace size seems feasible to operate at the standard FR4 pcb i
Draw a circle of the diameter where the leds will be placed. Draw lines from the center to the circle, rotate them by the number of degree you need them to be at. Then place your led's snapping to the junction of the line & the circle. Delete the lines (or turn off the layer they are on).
SinkPAD is a thermal management Printed Circuit Board (pcb) technology that makes it possible to conduct heat out of a led and into the atmosphere in a faster and more efficient manner. SinkPAD is an alternative technology to the conventional Aluminum pcb or MCpcb providing superior thermal performance for medium to high (...)
How High can you do hand waving descriptions :roll: without a requirement or a comparison is one example of an 6x3 array of XL Cree ledS on ALum-clad pcb powered by one of my surplus wall transformers 20
Hi, I am working on led bulb. I have made circuit . I have series connection of 16 3.2V led, and a 1K 1W resistor. But the circuit that is on bread board is working fine but with the same circuit on pcb the resistor is getting very hot. Can anybody tell what can be the problem. Mains supply is 220V. Thanks, Nitin
Recently the washer died and while checking LNK304PN and R1 (22ohm), 4.7u450v was replaced to bring it online. However when switched on, immediately getting PE error after ON symbol with wash cycle led's blink. Pressure sensor (E1) is already validated. The machine was working with a older version of pcb and I need to fix the new version and
