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

Have you moved this LED to a different dispensing head? I have seen some dispensing heads that are out of adjustment cause the same problem. Jerry

We're aware of no such specification.

Given that the LED work properly after being touched-up and that you don't have problems with other components, you may not be wetting the LED termination solderability protection during your normal reflow. Use a profiler to check the temperature on

I solder LEDs everyday from 0402 sizes on up. I work for an optical company so every product I make has LEDs. Some products have hundreds of LEDs per circuit. The problem is that clear materials are not filled materials and thus don't have the adv

Thank D.B. Cooper, actually this LED has 3 sides termination but no termination at underneath of LED. So this LED tends to float rather than performing solder joint during reflow process.

hi, lately I have problem with smd leds.After reflow 2-4% of leds are broken.I think , that reason is bad storage of components, because in our stock the tape with leds have not Moisture Barrier Bags.My question is ,how you storage components, which

Just a random thought, but we had an issue with having to replace faulty LED's on a PCB, and the solution turned out to be pre-baking the LED's prior to build. Just put them in an oven at 40C for 24 hours, then build. Result was zero defective LED's.
