I don't know what machine type you have or what the nozzles look like but we use a standard nozzle with an I.D. of either .8 or 1.5mm. We rotate and pick up the part somewhat slowly.

Has anyone developed a custom nozzle for these guys? http://www.osram.convergy.de/upload/documents/2005/03/03/14/47/LA_LO_LS_LY_E63B.pdf I've found that there is a deposit of epoxy at the base of the lens that can sometimes cause the LED to lodge in

We are currently having problems with running dome shaped fids. on some of our product. Particularly with the screen printer vision system the domes are reflecting the light to a point where the camera has problems seeing the fid. Has any one else en

Thanks for the reply, I do know that the HASL finish is "domed " on opposite sides of a QFP site & "smooth" on the other two sides. (ie. Sides 1 & 3 are domed, & sides 2 & 4 are smooth ) depending on the direction the PCB was extracted from sol

Has anyone tried producing domed joints for high voltage corona reduction on a selective solder machine? I'm guessing it probably won't work due to gravity, but worth a shout. Thanks, Rob.

Dane, I'll give you a quick guess before I log off; The reason you are seeing problems with dome shaped fiducials is probably because the machines in question do not use grey scale recognition. They asign either black or white( not 256 shades of grey

For those of you who use via holes as test points, and the via holes must be filled at the wave, is it necessary to have a "dome" on every single test point, or is it sufficient to have the via "filled" with solder? The ICT preson here insists that

Hi All, Need your advice / help. We have assembleon pick-and-place machines and we got some pick-up issues on certain LED's that are Dome Type. The LED's get off from the tape pocket during feeding due to the dome of the LED sticks on the tape surfa
