Hi all, We are having a lot of trouble with mis-pick trying to place silicone dome LEDs(3535 package) It seems that the silicone of the LEDs is sticking to the side wall of the carrier tape pocket. The vacuum nozzle would normally suck up the led an

Are these silicon based LED's? If so we are experiencing the same issue at our facility.

Are the parts kept in a humidity controlled environment ? Perhaps a little humidity is making the silicon "sticky".

HI again Dave, I was wondering what kind of problems you were experiencing with the silicone tape that led you believe that it wasn't the correct tape and question the manufacturer? Were there more failures and solder issues ? Thanks

According to the datasheet, this is a LED encapsulant, is that how you are using it? It also had a section on compatibility, which indicates that it is an addition-cure silicone prone to cure inhibition.

This problem has become a real issue with the tacky silicon used in many LEDs. Cree has recomended that the pull off angle be changed for the cover film as mentioned by the previous commentor. With these new silicon LEDs they are recomending teflon o

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.

Hello. We are building a CCA which has a silicone-based adhesive whose purpose is to bond the bottoms of multiple LED displays to heat sinks. Our customer wants the CCA to be tested for ionic residues per J-STD-001, but we are hesitant to test the

Are there any Siplace users out there that have any experience of the latest "smart feeders" for X series (version 3 I think, with built in handle and LED´s instead of LCD display) I am specifically interested to get input on any issues experienced w

We did this test, we opened the tape and turned it upside down, indeed some leds were staying inside the tape. We will try placing them next week with a fuji NXT line. We also contacted the manufacturer, apparently heat perhaps during transport coul
