Look here: http://www.acroname.com/howto/LED/LED.html If you don't know the current, experiment with different values of resistor. Starting with the highest value resistor that doesn't dim the light too much then lowering it as needed. Connect th

I assume your talking about the forward voltage (Vf) of the LED during operation? (Probably not the correct forum for this question but anyway...) My understanding is that 'Vf' is measured during the LED's operation at a forward current ('If') of 20

If you are measuring the voltage for a presence test that is fine. But you can not tell you the color of the led and have confidence that the right part is installed. Led forward voltages vary a lot between parts and between mfgs also. http://www.

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

One of my 8mm feeders is blinking the red led after the pick-up. With both buttons the motor works as expected (forward/backward), but after the nozzle pick-up the motor moves forward and then the red led blinks. pressing the buttons the green led l

I had the same question. We have custom nozzles made by Count on Tools. I believe we found urethane works the best for the silicon domed LEDs. Have you slowed the feed rate down on the feeder? Also adjust the top tape to the back slot on the feeder.

I am posting answer for anybody who finds this post : very price wise is HYDRON SE220 from ZESTRON....the most important for me is that in technical sheet there is description "highly suitable for power LEDs, SMD LEDs, and flip chip LEDs) which is in

I would like to know about specification for accept or reject LED which have defect such as,chip ,crack ,etc. this type of LED is surface mount device type. Thank you for your help.

I need advice for locating 23 Gull wing LED's (all in a straight line) in the x,y, and z axis for a SMT PCB. It is a Hewlett Packard LED (P/N HMLA-QH00-01). The application uses a CCD to detect the position of a ball which floats in a resevior for

We want to insert LED's on .100 center's with a UIC Rad 2. The LED must have plastic standoff on the leads before they are inserted. Are there any tape & reel machines that will put the standoff on the LED and then put the component on tape & Reel. A
