Has anyone ever ran into a 20mm pitch on a 24mm tape and reel. Our software doesnt have a setting for 20mm. we found a way around it, but i was curious as to how common this pitch is, and if other software or feeders have a 20mm setting.

EIA-481 standard allows the maximum pitch on tape to be 4mm less than the tape width (12mm width and larger). So it is within the standard allowances. As for how common 20mm pitch on 24mm tape is I can not say. I am surprised a 24mm tape feeder can not accomadate this pitch. There will always be anomalies though, I have seen many times 12mm pitch pockets on 12mm tape.

We use Samsung and our 24mm feeders have 8,12,16,and 20mm pitch settings. I have found 20mm pitch quite common. My favorite is yhe 12 on 12 our feeders don't support that, we have to put them up on 16mm feeders our cycle them 3 times on a 4mm pitch setting.

WE ARE USING MIRAE MX240. ON THIS MACHINE, THE FEEDER ADVANCE AND THE FEEDER PITCH IS CONTROLLED BY THE MACHINE/SOFTWARE AS OPPOSED TO THE FEEDER ITSELF. OUR SELECTIONS FOR 24MM FDDERS ARE 4,8,12, 16, AND 24MM.I WAS WONDERING IF THE 20MM PITCH WAS UNCOMMON, OR IF ITS A MINOR BUG IN OUR SOFTWARE. IT SEEMS TO ME THAT THE LATTER HOLDS TRUE. WE GOT AROUND THE PROBLEM BY SELECTING 4MM PITCH WITH 5 CYCLES.
