220 dollar IR reflow oven

image

Picked up this infrared reflow oven for 1400 rmb, about 200 bucks, in Shenzhen. It isn’t the at923 (or whatever) that shows up on eBay for $300, and lacks the viewing window. Comes highly recommended by Dimitri at SmARtMAKER, and seemed better built than the other one which was available at the stand next door. Still only two or tubes but the center area is even over the space of at least the eagle minimum size.

Also bought a hotplate for 300rmb, about 45 bucks. Also a metal solder paste squeegy to use with the boards and stencil on the way from Hackvana.

  1. Ian even take a stencil frame or Jig or machine it will be very helpful for applying solder paste when using stainless steel stencil… in Shenzhen as you know u can get steel stencils for 20-30 bucks very cheap compared to US… :-)

  2. Can you get those cheap stencils through a service, in a similar way to Seeed PCB? I’ve seen the Kapton ones, but the only stainless ones are local or US that I know of, never seen a cheap Chinese service advertised.

      1. Thanks Winston, I’ve known about Ohararp for a while, but the Stainless are preferable, especially if not much more than Kapton. Up till now I’ve just made my own, but if there’s a cheap Chinese service, that’s preferable, much less mucking about. Below Ian has advised Mitch is doing them, so I’ll check that out too.

  3. yup.. forgot about it so finding someone who does stainless steel stenciling finishes the job and can ship to Amsterdam quite cheaply better than those kapton sheet stencils. now we can see Ian stenciling more BP’s in workshop.videos :-)

  4. there are Chinese suppliers for stencil who can make and ship stainless steel stencil 30$ shipped in eBay and Chinese sites but not dedicated like seed pcb service…

  5. Iteadstudio provide a service for producing stencils. Not as cheap, but you can combine it with getting your pcb made.

    1. Thanks Sjaak, yeah I saw that (actually thought I posted about it since, but doesn’t seem to be here or I mucked up). Was a bit more expensive at $90 for a laser cut one and $45 for a chemical one, though they do come with frames. Also they determine the shim thickness, you can’t pick it apparently – not always ideal. I usually get my boards from Seeed, not Itead though, so a bit more freight, but still worth considering.

  6. We ordered them from hackvana.com, don’t forget mitch’s service which is based in Shenzhen. He is even setting it up for stencil8 for us.

    1. Oh thanks for the tip, I saw the interview but didn’t know he was doing stencils. I’ll have to check that out.

      1. That is what he is doing. Well have a review soon too, but I’ve already seen the PCBs and experienced the service and I think its great.

  7. Would be great if Mitch can get something going for PCBs + Stencils. I think Seeed also dropped 4-layer so they’re lacking that too.

    1. Thanks George, hadn’t noticed that. I wonder why they dropped the 4 layer? Maybe Ian can find out.

    1. That is the one I was talking about in the post. It was at the stand next door for same price. I read mixed stuff… Some like it some don’t. It has a glass window and mine doesn’t. Mine seems to have a bigger exhaust fan and Dimitri likes it so I thought I would try. Both just have 2 ir tubes and part of the work area is unusable. For single prototypes it should be fine though. Will let you know if it makes it to the shop and still works :)

      1. Thanks for the info, Ian! Whatever the case is unlike the Puhui T-962A the Qinsi QS-5100 must be really tricky to buy. I cannot find it on eBay or on any webshops.

        I first saw the T-962A at http://www.hoektronics.com/2012/10/27/super-simple-smt-stencil8/ and later at http://www.youtube.com/watch?v=U48Nose31d4 . Asked the creator of the second video where he bought it who let me know that it’s the “iddmart” shop on eBay. This shop is willing to sell me this ware for 280 GBP with shipping included to Hungary. I cannot see any sellers for the QS-5100.

  8. Today I noticed that Seeed has the exact same brand if oven albeit the bigger version. So there’s two endorsements. Looking forward to trying t and will probably pick up a solder paste dispenser and stereo microscope as well.

    1. Stereo Microscope I’d like, Paste dispenser, yep, that too, the oven I’m only interested in if it does good toasted Ham, Cheese and Tomato ;)
      hmm… now what profile do I need for a well toasted sanger?

  9. Interesting info on stencils. I’m fixing to go to framed stainless stencils with a stencil printer. I’ve been using Outfab.com the last few years they have a 12″x18″ 4 mil mylar stencil service for $35 (used to be $25) which includes shipping. They also have a 12″x12″ 7.5 mylar stencil for the same price. The only thing is they don’t take gerber files. If any one is interested I have instructions for how to use inkscape and gerbmagic to produce a file that Outfab can use.

  10. First of all I would like to thank Ian for great post. For the price of toaster oven + PID controller you can get this semi-professional device.
    I am not sure if this information would be useful for others, but if you are not travelling to China often it might be good option to buy this reflow oven. For the price I decided to give it a shot and asked long term supplier of components if they can source it by any chance. I asked to search on the market, but to my surprise in the morning I got a reply that they can buy it directly from the factory! The link is:
    http://www.qinsi.com

    It was the great news for me as it stated that I can order 110V version which saves me from the headache to buy extra transformer. The price end price (including 3 day DHL shipping and bank fee ended up to $370) A bit steeper than Ian’s but definitely worth it. I asked permission to share my contact and she graciously let me post it here.

    Mind it is not their core business. I am not sure if Ian got his oven already. I should get mine in 2 days. Will try to post my review here or in the forums.

    1. Fantastic! Thank you so much.

      Mine was released from customs an hour ago and should be here in time tomorrow for a Workshop video about it.

      1. I got it all planned in my head :) Dave Jones style EEV blog first person, first impressions, off the cuff reflow goodness! Honestly I’ve never really used either the oven of a hot plate much in the past, so I’m a total newbie!

      2. Yeah, then you’d have a window to see your Ham/Cheese/Tomato (oh sorry, Bagel ;) being grilled :D

        I’ve heard a few reviews that suggest the bad points of any of these cheap ovens are that you have to play around a bit because of uneven heat zones. But for the price, I guess that’s not a big deal.

      3. Hi,
        I bought a qs-5100 reflow soldering machine as well. However it is being held in customs because they need a ce declaration of conformity. Qinsi provided me with a ‘certificate of LVD’, but apparently its not enough for Europe.

        How did you manage to get it out of customs please?

    2. I see it is listed at 1600rmb, you could easily have asked for a 200rmb discount :) 1400 is the default price in the market as far as I can tell, and that could even be talked lower.

      1. I am not sure if they have same discounts on US version. Plus Janice refused to take any fee for sourcing it, so I decided not to push it to extreme. Again, thank you for sharing it!
