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.

That would be a 2012 (2.0mm x 1.2mm) in accordance with standardized naming convention.

1.5mm pad is not so ok in practice. You may expand the size to 2.0mm.

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

Hi, you want something that will not break down, and something not American then. I would look at the Fuji XP-143E (if you are not going bigger than 20mm x 20mm) or the Juki then. Also I would look at what they are predominately using in Turkey, as

Josh: Your 0.009" [0.228 mm] clearance should be fine. The minimum clearance should be ~0.008" [0.20 mm]. Is the 0.039" [0.99 mm] the measured or the expected hole diameter? While we wouldn't like it, we wouldn't be surprised to see 0.008" [0.20 mm

Hello. I think, good stencil apertures is 80% from pad. And stencil thickness is 0.15mm - 0.20mm. I use 0.15mm thick stencil almost every pcb. Sorry my very bad english but i too learning. :)

Do the parts sit directly on the PCB? Typical 2.0 mm Max is desired for the component to be off the PCB. Are stand-offs an option? The long lead wiggles as it passes through the wave and thus agitating the air out.Does your wave a "dancer" option?

The mirae machine does have the setting for 20mm pitch....it can be set on the machine software but i dont believe its on the offline software.. thanks

The stencil thickness should be 5.5 mils.The squeeze speed around 20mm/s,print gap 0.15mm,print separation 0.3mm/s.
