MSK, would help to know the exact type of LED you are talking about, and the size and spacing of the pads on pcb; and how and where the LEDs are reversed (always in the same direction or random ?) Also a picture might help.

A few of the LEDs on the cameras of my stencil printer are really dim. I want to replace them and not have to buy a whole new light ring board. Does anyone know what kind of LED they are? Any info would be appreciated. Thanks.

I have a few LED pcb's that have an aluminum substrate that are ridiculous to rework. They heat-sink like crazy and I can't reflow the bad LED's, no matter how much heat I apply. Any suggestions on techniques or equipment to use?

I have posted earlier on a UIC Radial inserter machine. We have the machine running after repair of the CnC head. However, I now have a process problem with a board that has 256x3 LED parts (768 LEDs in three colors) where only 50% of the LEDs can b

Hi, Why aren't the defective LED blinking? * Do the defective LED blink when removed from the board and tested according to the functional test that you used prior to assembling the boards? - yes,some of them. * Do the defective LED blink after the

We've found that storage of other LEDs from this manufacturer can be very important. On page eight of the datesheet you attached, it says: "It is recommended that LEDs out of their original packaging are IR-reflowed within one week. For extended sto

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
