We have a Quadra EVO (2014) if anybody has any questions. It's a fairly low cost machine  but has been perfectly reliable. It does 0201 without any problems. We don't have the dispenser option so can't comment on that except that even the dealer said don't bother.

Will be moonbeams as the Distributor down under here puts artifically high margins on everything.   I've given up on them and get much better support at much better price out of China.. And get things at the chinese dometic price, which is significnatly lower.

Can't really comment on pricing as we had no benchmark other than quotes from other suppliers for similar spec machines. The TWS was significantly cheaper when loaded with like for like numbers of feeders.
I didn't have the time or energy to put into getting a used or china machine with dubious quality.. This thing was pumping out boards the day after it was installed.

Thank you again, its huge amount of information if we decide to proceed with the line. Paste dispenser is out of consideration.
TWS Still looks compelling to me for some reason, anyway for the moment i dont have further information, my task was to do some basic research.

I once worked on some pick and place, I dont remember the brand but SMD head had funny metal clamp, clamping onto head after each pickup (aligment)? That was some time ago on my first internship, so i was just aligning some ICs for pickup and then positioning boards etc.

Hi Macck,
i know the quadra well, both the meccanical and the laser one, not the evo.
Meccanical use meccanical grippers for centering and works down to 0603. Laser works down to 0402.
Laser it have cameras and cognex laser sensor for part centering.
Meccanical have support for rs232 vga jpg camera instead of the slow align spring based align jig.
Just connect it on COM and the software recognize it.
Meccanical do 2k7 cph an laser 3k6 ipc.
The difference between evo and laser/meccanical is that evo run linux with modern interface, the other use dos software.
For the dos software you definitly need a small introduction course, 2 day, in order to be productive. There are a lot of external
dos software for feeder diagnosis, laser sensor diagnosis, .... that are absolutly needed to know and don't are intuitive at all.
Further for meccanical Feeders you need to manage the feeder database at file level in order to be productive.
Meccanical Feeders costs 150 Euro and Laser/Evo cost 300 Euro, always 10cm width, for 8mm there can be 8 slots inside 10cm.
If using this machine in production 8-12h/(working day), every year there is a necessary replacement kit, 96Euro. This includes ventury ejectors stages,
cables that are subject to moves and other small items.
As it's a dos machine, install dos ethernet card and working is easier, evo is annother story as linux have usb support, but i don't know that machine and i don't
know if users have root access or what access levels there have at all.

I'm not using a "China" machine.. I'm using genuine Japanese Yamaha machines.  But i'm not paying the artifically high price that the distributor in A/NZ thinks is appropriate.  When you go to the factorys in china, you wont' see many of them using 'China' machines.  they are using Yamahas/Jukis/MyData etc etc etc...   There are plenty of folks there supporting them. ( becuase there are lots of machines ), they have parts in stock, and they have the know-how.

I was referring more the Neoden type machine that look more like hobbyist machines. Yamaha gear was way out of our price range, are you saying you got Yamaha gear directly from Japan yourself without going through HR? I'd be totally into that hahaha.

[mrpackethead]

I bought my first yamaha gear 2nd hand. The machins were orginally sold by HR, but they really did'tn want to know about them, and to be honest, i found the entire experience with them to be quite poor.  They certainly did not want to share any information and i felt like they were trying to make it difficult for me.   

Anyway, i accidently found a Chinese dealer who makes 3rd party Feeders..  15% of the cost of Yamaha ones, and they have been working without issues.     They also sell and disribute yamaha, and are happy to send it out here.

I have no real complaints about the service. I do feel like all the Ausi suppliers charge a decent margin under the guise of 'commissioning'. We pretty much getting the same story with the CNC mill quotes.

Yup. been there as well.  Aircompressors,  CNC mills,  Laser Cutters, PNP and tooling in general.     Plastic injection moulders is another big area of execessive margins.

Hi D3,

I was on my way to buy a TWS DVC EVO, but I was a bit disapointed by the demo of the distributor. So may you answer to some question as you're a regular user.
-during test I saw that the X axis shaking a little bit (even at idle position), the down cam image shift a bit from left to right (and if you touch X motor you feel a little vibration). Do you have the same thing on your machine? The demo guy told me it's normal and we did some placement test and it placed quite well components.
-if the machine is not cycling normally, before startup you need to remove nozzles (and put them back on the plate) as the machine doesnt detect it at startup, you agree with it?
-What's your feeling about feeder does it works well  and reliably?
-to do a new job, you set the origin point of the PCB and how do you check if the PCB is not a bit rotated (as with two point)?
-on software there is no ability to modify a lot of components, per example if the defaut rotation of a component is not aligned with the tape position of the component on front feeder, can't you apply an offset to all same components?

Thanks,
