    Mycronic has introduced a new pick and place machine, the My Pro A40 DX, which features a new high-speed head that can cover over 98% of commonly used components in the pick and placement process. The new head allows the machine to run 48% faster in throughput compared to the previous version.

    The company has also developed a new user interface to support operators in the production flow.

    Additionally, Mycronic has integrated a screen printer into its portfolio to improve the solder paste deposition process, combining it with its SPI capabilities and jet printer to create a zero defect printing solution.

    The company has also introduced the My Pro Link, which connects the various machines and processes in the pick and place process, and the My Pro Connect, which allows customers to connect their machines to their existing ERP and MES systems. The machines are also Hermes compliant, allowing for data extraction and process control.

    Trevor Galbraith spoke to Clemens Jargon at Productronica about these new developments.

    Yes. So a couple of really interesting products this week. We’ve got a brand new platform behind us, which is the My Pro A40 DX. This is the successor to the My Pro 300? What makes it different, because from the outside it looks pretty much the same?

    This is in fact a new machine under the same hood. So what we have done is develop a new high speed head, which is the MX7, and the high speed placement head is the heartbeat of the machine.

    This new head makes the machine running 48% faster in throughput than the previous version, because it has seven different nozzles, that can move independently. And the real big change here is that these high-speed heads can cover more than 98% of all typically used components in the pick and placement process. So there is rarely the need for the Midas, which is a single-pick head.

    I see. So basically what you had before was a chip shooter configuration and then the Midas took care of odd form or anything a little bit bigger. But now you’ve expanded that by using the new head to cover a much wider range of your components?

    Exactly. So there’s almost no need for the single-pick head anymore. That means the high speed head, the new MX7 can cover the majority of products. But when you change the high speed head in a machine, that means you need to redo almost everything. So it’s brand new software under the same hood, in fact a complete new machine. Redesigning all the software enables us to make the new high speed head run so fast. We have also introduced a new user interface, a graphic user interface.

    We have also changed how the operator operates the machine because we have recognized here that new operators want to run machines in a new way. But we have done it such a way that we can still keep the old software, but also use the new software. And this new user interface is not just another way to operate the machine. We try to support the operator in the production flow and how he runs the machine.
    So that has also been paired with your improvements on the printing side because you’ve got a zero defect solution on the other side of the booth there, which comprises a stencil printer, which I’m surprised to see you having. Plus of course your famous jet printer next to your SPI system. You’re using it in a closed loop configuration. Can you explain how that works?

    Because the jetting machine is not so fast when you, for example, connect them to A40s, they are now as fast as three jetting machines. But with this fast pick and place platform, we now needed to also have a faster solder paste process. This is why we added a screen printer.

    I see. That makes sense.

    But it would be too easy just to add a screen printer. So therefore we thought, how can we improve the screen print process? Because we both know, as everybody knows, the majority of concerns and issues appear and happen in the solder paste deposition process.
    Absolutely. I mean, the famous metric everybody uses is 60 to 70% of the defects come from the printer, but of course the vast majority of these defects are missing paste or insufficient paste.

    Exactly.

    So you’re going to top up the missing or insufficient paste with the jet printer?

    Yes. And what we did then was that we said we need to bring a screen printer into the portfolio to keep up with the line-speed when needed, but combine the screen printer with our SPI capabilities and the jet printer and make it a zero defect printing solution. That means the pattern of the screen printer can be checked with the SPI and when there’s any paste missing, a dot missing, the jet printer can add on. So there’s the closed loop functionality between screen printer, SPI and jet printer to have a perfect sort of paste pattern for our customers.

    That’s very impressive. So putting that together with a couple of A40s, which by the way will reduce the overall footprint on the line because if that takes the equivalent of three machines. And then controlling all of that is the My Pro Link. So we’ve got a fantastic graphic here (Figure 1.) behind us that shows the software configuration of the My Pro Link and how that works. So can you explain what we’re looking at here?
    Yes, exactly. So the hardware’s essential. We have updated the pick and place, we renewed the high speed head. We changed the GUI. We optimized the process flow, but we need to look at the entire process flow of the pick and place process. It starts from material handling, goes through screen printing, SPI, jet printing, pick and place and AOI to make sure that we have a perfect throughput and a perfect quality. But this has to be connected together. This is why we have the closed loop on the printing side. This is why we connect the SPI with the AOI via the My Pro Link to process control. But we also have introduced our My Pro Connect, which is in fact the CFX equivalent.

    Okay. So this is the My Pro Connect, which is the linked via CfX up to the ERP and the MES system?

    Yes. So customers come with proprietary solutions. They come with standard ERP/MES solutions and we want to be flexible. That means we have the interface and they can connect into their factory surroundings using our machines.

    And the other thing I noticed, which of course is a given, is that each of these machines is joined together using the Hermes line automation solution.

    Yes. So we are now fully Hermes compliant on the whole portfolio. They’re all connected to each other. And that means we also fulfill your industry standards.

    Excellent. This is important because you can then extract all the data from all of these machines and processes and pass them up into the MES for traceability and trend analysis.

    Yes, because process control means data collection using the AOI, we introduced AI tools to make the AOI even more precise, even faster and even more reliable. All these data goes into the data control system, to make it a controlled process for our customers.

    Excellent. Well, it’s an impressive system. It keeps continually evolving.

    Thank you.
