Manual/Semi-Sutomated SMD line

@SMTech can you post some more screenshots of that application? I'm very interested in it.
Or do you have any documentation (which includes screenshots)?
What I get from your screenshots is that the machine has blow-off capability and they made many steps parameterized (which is pretty nice).
I also have customized pick and place speeds (which is essential for some parts)

[SMTech]

Every setting screen has an attached HTML page listing every button or setting and what it does. I don't think an index page exists that makes them navigable outside the application, and it probably breaches all sorts of copyright to dump the whole thing on here. What those pages do not do is explain why/when you might want to use certain settings so you need to use a bit of trial and error, educated guesswork or perhaps a hint from support.

On a platform this stable the placement speed isn't really something you need to adjust that much, but it doesn't hurt to slow it down for large heavy ICs or if perhaps you don't have the requisite specialist nozzle that would deliver the best result when picking. On that note I can tell you that things like specialist nozzles are hardcoded into the software, if they made one later than your software release, $$$$ to upgrade to be able to use it.

Pretty much every setting you might want to fine tune is in the software somewhere, the software is divided up into sections based on task and by extension user role. You can see those on many Youtube videos, each section is distinct, if you are placing, you place, you don't interact with or alter XYR here, that is strictly a teach operation. There is also a secret(ish) screen intended for the engineer to run specific checks, update module firmware, calibration or alter factory settings on the electronic feeders. You can see the machine has no force feedback on placement (a premium feature you will find on some other machines) which is essentially what the additional Z move setting is making up for. As a pure vision system using a single upward looking camera for component identification it also is not doing any coplanarity checks or device thickness measurement, again this is  party trick you might find on some other machines possibly in place of force feedback.

Cameras and Motors are controlled over Gigabit Ethernet, linear encoders are RS422 and everything you can see is a chunky button as it is designed primarily as a touch driven interface. Something you might find on a Yamaha or similar is a set of buttons on the chassis or corded remote that move the gantry/head for manual teach or pickup tuning. On this platform this can only be done from the camera view using soft buttons.

All you need is an unframed stencil with 2 holes in the stencil and 2 matching ones on the PCB, 30mm spacing stencil to PCB hole - I have a component defined with the corerct sized/spaced holes in the appropriate layers, so just need to place 2 of these at the edge of the PCB
https://www.eurocircuits.com/ec-registration-system/

This works surprisingly well once you get the hole sizes dead on - 0.5mm QFPs on a 250mm PCB are no problem at all. The EC unit does a pretty good job of tensioning

Another benefit of a jig using unframed stencils is they take a lot less storage space!

Is there any Knobs to do some manual alignment on the Eurocircuit stencil mate?
Or it completely relies on using their stencil registration standard?
In other words can I use it with a random frameless stencil ?

Thanks!

No manual adjust - it relies entirely on the registration, and this works fine.
You can do a simple hack to use un-tooled stencils/PCBs - place a sheet of card (or scrap stainless stencil) between the magnetic PCB holders and the metal base, sized such that the edges are accessible from the sides when the stencil is hinged down. You can then pull on the card to move the PCB position relative to the stencil - not as easy as with x/y screws, but entirely useable.

For those looking for entry level machine and accessories there is a trade show Productronica in Shanghai China on March 20-22 this month.

@SMTech,

What is the "Theta movement speed" setting from the first image you posted?
I understand the YX and Z, but have no idea what theta is referenced to.

Thanks.

Theta would normally refer to rotation of the nozzle.

Indeed, I'm not sure I have experimented with this variable. I would imagine it is mostly useful for larger things like long connectors where angular momentum might cause slip

Yes, angular acceleration is most likely what this parameter adjusts.  That is what would make larger parts slip on the nozzle.  Up to a point, using a larger nozzle gets more grip on the part.  But, I have had large caps and inductors slip on the nozzles.
