I am currently placing LED's with a RAD 5 machine and developed cutting problems with a specific LED. I am not having problems with other similiar LED's where only the color is different. After dispensing to the clip all is well. After going through

We have this problem only with one manufacturer of LEDs. Avago LEDs give us the problems where SunLED and KingBright do not. We put a magnet under the embossed cover tape. The magnet is mounted to the feeder. Holds the part in the tape pocket. L

Hi All, Need your advice / help. We have assembleon pick-and-place machines and we got some pick-up issues on certain LED's that are Dome Type. The LED's get off from the tape pocket during feeding due to the dome of the LED sticks on the tape surfa

We are using a custom made nozzle, designed for this particular LED. The dome of the LED is also custom made, the diameter of the lens at the base is 2.9mm while the substrate of the package is 3.3mm, so this gives about 0.2mm spacing between lens a

Hello I experiencing major misalignments. I am using a Nichia LED package size@ y=.086,x=0.33mm, with recommended solder pad pattern x.086mm, y=.033. Note here is the kicker the PCB pattern does not meet this requirement. The PCB pad landing is based

I�d appreciate assistance in trying to resolve a placement/soldering problem. My company has designed a board which uses a large number of 0402 LED�s that are .028� high. The LED�s need to be soldered so that they point straight up and are not til

I need some advice about a problem that happened in a SMT LED: The failure symphoms of this SMT LEDs is that the LED body itself seemed to be functional, but when soldering on the products, it showed good wetting and soldering, LEDs are bright and l

Hombre, presuming you are doing this as enhancement for looks, I have some comments. 1. LED's seldom run on more than 3 volts. 4.5 volts max for some special types. Because the car is 12 volts all over, you have to use a resistor to reduce the v

I read a few posts here about resistor in led applications. The thing is, the resistor has clarified as this shows:was always use with a power source delivering a higher forward voltage than the led could tolerate(ex: a 9volt battery hook up to a 3w

Most likely there is movement during reflow. How about conduction oven over convection oven for reflow? This is a small PCB with the LED sitting on a Flex-Rigid extension from the PCB. I was thinking if the stencil aperature for the LED was to be cu
