If the Leds are not in close proximity then LDR's can be used connected to a node on the ICT/wired into a micro for a simpler board - you can then test for luminous intensity as well as absence. Else you could use a cheap CCD camera with some simple

Hello, On customer want to make a aluminium board. It will have SMD Led on it. Like I never "played" with this before can someone tell me what I know to know on that new thing. What kind of reflow profile we need. What just I be aware of, is

On the board, LTST-S320KGKT (LED) was supposed to be placed as shown in the figure. The pads and silkscreen with legend were also made as shown in the figure. But after the part was placed on the board, I realized that the sizes recommended by the LE

We use plastic standoffs that fit between the LED and the board. Live well, live long. For more than you wanted to know about standoffs: http://www.reedlink.com/ProductInfo~Productid~158255~ProductName~LED-Standoffs.html

Hi George, The extra pad is just for mechanical strength, it's not connected. As the Liteon LED is just a side view & nothing special you may get lucky and find that a someone like Rohm, Avago or Osram make something without the centre pad that stil

We are looking to possibly counterbore a coule of thru holes in one of our PCBs. We would counterbore the top side, and the only trace is coming out of the bottom side. The reason is to mount some LEDs flush with the board. They have some flash wh

I don't have any data (haven't tried this), but it doesn't take much thought to see that determining the risks associated with simultaneously applying compressive and rotational forces to the end of the barrel, not to mention chewing up the copper, i

It sounds more expensive just at face value than better LEDs, and potentially MUCH more exensive due to failures if there is any kind of stress on that weakened connection.
