Hi Wayne - PM Sent ith details.

[quote author="wholder"]I'm interested in obtaining one of these machines.  Is there a concensus on the best way to order one that works in English and runs on 110V?

Well, we use it commercially for msop, We have s couple of boards that use dfn and one using a qfn
Our board failure rate is about 2% . Sometimes real life use is the best gauge of a machines usefulness. In our case, this thing has paid for itself a 100 times over! I'm happy with it. :)

Vision would be nice - but for te extra cost it's not worth it for us given the volume we do. We have 15 boards per panel, and it does a panel in about 3 minutes - I spend another minute or so checking alignments before cooking it, so 15 boards / 4  minutes.

I have changed my machine to English permanently too .. YAYYYY.. The Factory are very helpful and I am greatful I got their details. No prob giving me the password to the machine so I was able to save the language perm. They have even agreed to sell me the additional spare parts kit that was not offered to me by the dealer I got mine from. We are looking to maybe upgrade the TM220 to the 240 for the additional capacity - If we do it will be direct with the factory!

Out of Curiosity - Who here has bought one of these and what do you use it for ?? - Am I the only one who has a commercial operation ??

It's a QS-5180C from Qinsi Technology (Shenzhen China). Most of these IR ovens are similar - it's all in the configuration!!! I got the guys at Qinsi to configure it for me whilst I was in their office in Shenzhen - the profile is specifically for Sn42/Bi58 RoHS Solder paste. Its important to match the profile up with the solder being used.

0603 is the smallest we use - I see no reason why it couldn't do 0402's - the specs say it can... Our ICS comprise mainly SOIC (150mil) although we do have a product that uses a TSOP-40/10x16x0.5 and it has no problem.
Although some components appear to be placed crooked, a good reflow oven with accurate profiles will cause them to be pulled into place – we have this and it’s amazing how perfect finished boards look! – only occasionally does a component rotate off a pad and this is due to one end not coming into contact with the paste at all. I’ll post a few pics of before and after reflow.
Realistically, for the price I don’t think it can be beaten – look at the SMD PnP machines form Manncorp in the USA, they have a manual machine for $4295 (http://www.manncorp.com/smt/prod-179/sm ... place.html ) Have a look at the specs then you see how good the TM220 looks!!!..

Yep - Agree, eyeballing is what we do too.. As for language - I have the setting, but changing it has no effect ! .. is there something I am doing wrong ? - In fact, mine is 1 by default and that is Chinese .. Maybe you guys have different firmware, but I can't find it. Who did you get your machine from ? - I got mine from Qinsi Technology in Shenzhen . cost 39000 RMB (about $6200 USD :( )

On Volume - This thing can keep up, we have the odd 'stuff up' I think the main thing we did to increase reliability is to only allow it to use a single head - so when the PnP file is created, we have all the Head 1's first then head 2's last. Not the fastest method, but in the long run it is much faster due to reliability.

It seems to fault when trying to pick up a 0603 size cap with something else - the 0603 falls off .. low vacuum maybe, if anyone has any ideas I would be grateful.....

Hi Royco,

We developed an in house windows app to create the PnP file for the TM220. It takes the DipTrace PnP export without change. The system connects to a SQLServer Database and holds all the important stuff, like what components are on what stack and what head to use for each component - also automatically creates a file for panels, just feed it the panel size, boarder, number of horiz and vert panels and it does the rest. It's still a WIP, but when it's finished I may consider making it available publically. It's becoming quite sophisticated …

Cheers
Keith

My supplier told me it was not possible to change to Ehglish  - which I find hard to understand given the maual has english menus in the photos. 

We manufacture about 20 panels a day, each containing 15 boards.

We use DipTrace software with an interface program to create the TM220 file - the file allows us to panelize

Hi Guys,

I have a TM220A and have been using it for about 2 months now in a low volume production environment. Not too many problems - the occasional dropped component, tape not advancing etc. I bought mine from Qinsi in Shenzhen in November 2012, I visited them and went through it all then shipped it back to australia along with a couple of SMT ovens, stencil printer etc. The guy at Qinsi has 0 english, the manual = chinese, the videos = chinese, the machine = chinese. He told me (thanks to Google translator), you cannot change the machine to english!  - I am confused as the chinese manual has pictures of the menus and they are in English !!!! - does anyone have a solution to changine to english ???

I'm pretty happy with this machine, we know it wont last for ever but it has already paid for itself over. When it does die, I think we will invest in the 240 as the limits on reels is starting to hit us...

I just returned from Shenzhen in Southern China where I bought one of these. Appart from the lack of English on the menu (and no multi language support), the machine is well worth the $$ I compared to many machines around the world and this is by far the best value for money. We got it into production with about a days programming and testing and it's faultless. I am considering buying another to sit along side as the only real limitation is the reel capacity. I need more 12mm feeds.
Instructions are in Chinese and no softcopy has been made available to me which is a pitty as I could have translated it.
