Hi all

Everybody seems to be touting the fast changeover capabilities of the Mydata machines. What is it exactly that makes Mydatas so great in this (very important) area, above other brands? I am not attempting to play down the Mydata, I am just genuinely curious and would like to know users' opinions.

They are very long with lots of feeder positions & have a fast tape loading mechanism. They are also easy to use and upgrade, and are cheap on the second hand market.

However, on the flip side they are slower (the hydra figures are just dreaming as they are usually based on gang picking), not as accurate (again people may get good results, but nothing close to a Fuji, Juki, Siemens, Assemblion etc.) and have a large footprint.

Thanks Rob

So if it is only up to feeder space and fast and easy feeder loading mechanism, then surely most brands with feeder exchange carts will be equally fast or even better when changing over, provided you have a sufficient number of exchange feeders?

Thats the drag - feeders don't come for free.

Also depends on your budget - if you buy a good machine from the off then you can always add extra feeders over time & as your budget allows, however if you start with a ok machine and lots of feeders you can't really go anywhere.

Your process makes a bigger difference than the machine. I worked for and OEM with Panasonics. They eliminated all 5% resistors, wider tolerance capacitors, and went with as many dedicated feeders as we could. We also staged jobs. We had one running, one set up and one with feeders being loaded.

I am a fan of Mydata but process is more important than which machine.

The next advancement is Dynamic Changeover. The Contact Systems C5 machine is the only machine you can actually set the next job up on while another job is running. This is due to high feeder capacity and feeders that can truly be removed and replaced while the machine is running. Email me directly if you are interested in more information about this unique feature.

You mean the only machine other than Mydata.

I've run jobs where not all the feeders would fit. On Panasonic I needed two programs and non-intelligent feeder swaps. On Mydata push the button on the feeder magazine and pull it out and then put in the other one while the machine is running. The Mydata automatically recognizes the magazine.

The Mydata magazines even lets you know if it has parts that are needed in the program. And the Mydata optimizes on the fly so you can pull out magazines at any time.

Hi Greg,

I would beg to differ....

our ancient fujis could have a new job loaded up on one feeder bank as it was building from the other.

Hi,

What is it with this Contact Systems guy, there is no advice in that email from an experienced user, just a sales spiel. No of much use.

you are correct Rob--my bad. I was thinking only of machines still being produced today. Plus the Ancient Fujis were capable of only a limited component range thus you changeover for the whole line could not be completed--only the chipshooter--or am I wrong again?

hello again Grant, the inquiry was about fast changeover--some people (you, for instance) may not be aware of some machines capabilities or changeover concepts even with your vast experience with Mydata and Fuji.

Yes....the Fuji's were quite limited in the component range.

They are only capable of 8mm-44mm.

Poor Fuji.......

Call me Mr Picky,...

but you can still buy new Fuji Chipshooters:

...and they'll still be working when our kids have shoved us dribbling into retirement homes.

In answer to your other question, as the chipshooter carried the bulk of the feeders you only need to use one side of the fine pitch/odd form placer, so you can load up another job at the same time, on the other side, keeping out of the way of everyone.

Welcome back,

Rob.

Hi,

From what I can tell the guys who still use these CP8 machines are in China, where they run incredibly complex stuff all day, and don't change over as much. Doing computer motherboards etc. I visited some of the factories, and they had over 20 lines with 3 CP7's and 8's per line, it was quite amazing.

Hi,

Yes, it's me again getting more tired of watching you hijack as many threads on this forum as you can to run marketing campaigns.

> the inquiry was about fast changeover--some people (you, for instance) may > not be aware of some machines capabilities or changeover concepts even with > your vast experience with Mydata and Fuji.

I guess if someone asks about soldering flux comparisons, your going to add a post that says something like "Contact systems have been making PCB's that use flux since before you were born!" or something like that?

We can have a competition to see how many threads can be twisted into a marketing post for some non-heard-of garage based pick and place machine company?

Regards,

Grant
