Don't count out a wave pallet. if the led's are not an extremely tall part a pallet might be just the thing for running something like this at a higher volume.

Rohm make them & call them Backfires: http://www.rohm.com/products/databook/led/pdf/sml-812.pdf The only problem is on some applications you may have to use light pipes.

Fritsch placeall600 vs Essemtec FLX2020

Electronics Forum | Sat Feb 10 21:24:16 EST 2007 | ChocBar

We are looking at purchasing either an Essemtec FLX2020 or Fritsch placeall600 pick & place machine. Just wondering if anyone has any comments (Good or bad) concerning these two.

Hmmm. Judging from the overwhelming response, I'd say these pick and place machines are not very popular.

There's no real point in them now as for not a lot more you can get an I-pulse, Samsung, Mydata or Assemblion machine, or a good second user machine for the same or less.

Just out of curiosity - is it possible to enter placement positions in interactive mode (using camera image) on the GSM1 series? - Deni

I have two gsm1's and I don't believe the current software can do this. Assuming you are not importing cad data, that would be the only way.

simple doubt about reflow profile

Electronics Forum | Mon Feb 12 17:24:51 EST 2007 | dave

250-260ish seems a little on the high side ? Depending on the board density and components 230-245 should suffice. Again time above is usually preferred between 30-90secs but again it really depends on the PCB Dave
