We're having an intermittent fault with a QSV-1 where it will on occasions oscillate violently during a run and this usually results in 1 or both Z-rods being destroyed, along with the nozzle currently fitted. This has been on and off for the last 2

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.

Hi everyone, I was recently trying to troubleshoot a bad floppy driver on our QSV-1, which actually worked, I was able to read floppy drives but for some reason it all went downhill when one of the green LED's turned off and another red LED turned on

Indeed, stickiness of LED dome varies from batch to batch. We didn't have much success with adjusting pick&mount settings. Also, usage of other nozzle (recommendation from SMT manufacturer) didn't help. Usually, we have a good experience with similar

They are very finiky. If you have good solder paste, and a slight down pressure, to make sure the LED is "stuck" to the board, you should be able to place it. Pick it up on the center of the flat, NOT the lens. Even with the vacuum turned off, t

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

Clark, Which component type are you using? Deform? also, is this a domed led? and if so, are you using a nozzle with an approriate ID to seal on the body? Not every LED may be able to be placed with a 4791. Todd

I found it on white led. It's the gel lens sticking to the nozzle. Instead the yellow/blu/green led's have plastic lens. Use the smallest nozzle possible.

Using the 72A FNC nozzles to place 3216 resistors, and 74F nozzles to place PLCC6 LED's. The LED's ar 5mm x 6.5mm x 2.4mm tall.

Hi everyone, Any idea where can I purchase a nozzle for 3535 LEDs in general or Cree XPE specific, for a Philips Topaz/Emerald machine?
