NeoDen YY1 Pick And Place Machine With Under $3K Price for Hobbiest/Low vol Usag

Right now it sounds like their only reason is that they don't want to write instructions for plugging in an STLink dongle, or couldn't be bothered to write some sort of bootloader that could install updates off a microSD card or USB stick.

I think they are protecting their code.
I told them that I probably wouldn't buy one because of this and they are fine with that. And they know how much public exposure I can bring them. So don't expect them to change their stance on this.

Brymen do the same thing, although they do trust dealers like me with the HEX file under NDA.

Someone with spare boards leftover from past upgrades could absolutely test this.  They'd just have to see if code readout protection was actually enabled on the microcontroller.

Of course its still possible to protect the code without limiting distribution, by using some sort of cryptographic method within the update process. But that would require a fancy bootloader to install updates, and obviously requires a lot more engineering effort than they want to put in to this.

You'd usually only go to that effort for a high volume more consumer oriented product.

We've had ours for about 8 months. I have designed and manufactured components (heads, frame systems, etc.) for openpnp users for years so my expectations were quite tempered. Precise, repeatable motion is hard. I have to say that we are very happy with this little machine, and with dealing with Neoden in general. I was messaging Tonny the other night about completely custom tape feeder modules and custom strip tape holders and they were happy to oblige.

We created a YouTube video on it when we got it, setup and initial tests etc. I have footage for a follow-up video where we pull the YY1 out of the cupboard after sitting in there for 2 months, turn it on and just try and assemble our boards with no other preparatory action.

There are certainly some math issues hiding in the firmware, but overall it has done all we ask of it. We assemble about 54 PCBs in a sitting, which after setup, pasting, flowing, mucking around (deciding to tweak some things along the way) is about a 6 to 8 hour process. We used to spend that long just preparing our old PnP to run these jobs. Feeders have been great for us. Maybe twice we've had to switch out the little friction parts on the peelers when they pull the tape instead of just the cover tape.

One outstanding 'issue' is that we cant get it to place TQFP 48 processors perfectly, at least 50% of them need a slight bump with a steady hand and tweezers. I have not asked Neoden about this as it is not a major concern for us, I did not actually expect those to be perfect every time on a $3000 machine.

I agree that not being able to update firmware remotely is a major detractor, but we've been happy with ours as-is, and if some major changes happen we are ok to spent $200 on parts to make it happen.

Regards,
Peter.

I have been rather pleased with my YY1 also. Once you understand its quirks and limitations, it's actually a nice little machine.

Can you pls share a link to the video?

Exactly. I find it perfect for 0603. For 0402, there shouldnt be so many board in one panel. Because the head drifts. For 0201 I guess, there should be only one board at a time.

Here is the first video. I have not finished the follow-up one yet.

Can someone share demo P&P files ?

Bought the Neoden YY1
Spent a couple hours setting things up and getting my kicad pos files converted to yy1 formatting style, I struggle for a while tuning the USBC tape feeder (can't seem to test pick tapes in pitches other than 4mm) and then it kept dumping parts in the trash bin Lo and behold the vision uplooking camera is completely down! No LED lights, no camera view just absolutely nothing! The LCD works fine it lights up at the start but it's completely dark otherwise, the camera is feeding it no data.

Right now I'm hoping it's just a power cable that's not plugged in but all of the cables I see on the left side of the machine seem to be seated correctly hell it looks like some are encased in resin or glue. I'm loathing opening this thing up, what a complete kick in the nuts.

I went to test this device in the office of the Neoden distributor in my country ( I'm serious, I moved cities for this.). It is a terrible machine for 0402s, it works well for 0603 and above, but when pulling the reel towards itself for the first time on the tape, it spills 15-20 components on the floor. If you are going to work with 0402, definitely do not forget to take a microscope and a JBC package for manual soldering because the results are terrible with 0402.

I offered to use it with paste, the distributor did not accept it. He stuck double-sided tape on the pcb, which contained too much adhesive. I told him that it would not stick that well with paste. However, despite the double-sided tape, the 0402 components were lying on the pcb in an upside-down manner. These are my experiences. The results are good for 0603 packages, but as I said, the sector is shifting towards the use of 0402 components. If you do not want to have a headache, I recommend that you save your money and invest in devices worth 10-15k dollars.The problems of such devices are that the device vibrates due to inertia against acceleration. When the motor moves on the axes and suddenly wants to stop, the device is exposed to a tremendous vibration. The solution to this is to add weight to the base of the device and mechanical simulations. I cannot understand why they do not add concrete blocks to the base of the device as modular.

At the same time, the mechanical assembly phase of such devices must be very precise. If you cannot adjust the torque on the screws well, the chassis will start to stretch. Therefore, the chassis must also be machined with a very precise tolerance. However, these are things that increase the cost. In addition, such devices are developed with a focus on making money. The engineer who designs the firmware does not understand software architecture. You will encounter tons of problems among the spaghetti code. (While trying to fix a torn stitch, another stitch tears through the fabric.)

Hello community. I am trying to start working on a new neoden. So far the result is negative. I am doing calibration. I am trying to adjust the feeder, but the machine is trying to take elements with an offset.

Here's the problem. I haven't found a solution yet.

For the calibration function with the little black paper, you use the down facing camera to put the crosshair on the mark it makes. Not the up facing camera to center the tool directly.
