Re: Again, another feeder design
when you fully compress the spring than there should be enough pressure to trigger the switch. If not user some other kind of detection mechanism to detect smaller changes in height such as optical, or magnetic. You would have to redesign the head mechanism anyway. Worst case you could send the sign...

The Samsung nozzles and holders are pretty available. -- I have a nice CNC , I could try the design next weekend if the files are available. You can get the real sprocket of samsung and other feeders on ebay. maybe this is a good alternative for this ? Could also cnc a mould and pour polyurethane to...

Re: MELF
I also put the smallest one in the set that came with the liteplacer. It creates some kind vacuum buffer that seems to help with sucking up components. The cup is not even touching the passives or whatever but it still works. This might do Ok with MELF. But if it is possible it would be easier to ch...

Re: MELF
the difficulty will be in picking them up , not placing them.
Juki and the likes have custom nozzle for this:

This is just something that you need to try out

Re: MELF
I have done 0.5mm qfn and 0603 with good accuracy. No problem.
I put the chips in the pickup location , the component filter detects the center and the rotation offset.
0201 (imperial) is pretty high end. 60-80K pnp have troubles doing these reliably.
I would just try and see what happens.

Re: A whole slew of updates to the RMOD software
use a small roi (as you pretty much know a window where the component will be in) and you can do very fast detection. This should not take more than 50ms. You could also use one extra camera that looks at all the feeders all the time to do this :) Camera's are cheap , vision is pretty good and compu...

Re: A whole slew of updates to the RMOD software
Are you doing fast placement or normal ?
In normal placement the downcam looks at the component and determines the postion? + rotation offset (AFAIK)
or I could be completely wrong anyway on my board (0603) they were pretty spot on using mounting holes as fiducials.

Re: A whole slew of updates to the RMOD software
You might want to upgrade your down camera. The components seem a bit much off.

Re: Clarifying software options
liteplacer DEV is quite good and stable. Knaster has more features but possible less stable / larger bugs.
