In this episode of DIY or Buy we will be having a look at reflow soldering plates. I am familiar with hand soldering, hot air reflow soldering and oven reflow soldering and I was looking for a better technique that is easy to pull off and not as bulky as an oven. That is when I found out about reflow plates. So I bought myself one for testing and around the same time a viewer of mine reached out with a DIY solution. So in this video I will test both versions and ultimately tell you whether hot plate soldering is awesome and whether you should DIY one or simply buy one! Let's get started!

Hey GreatScott, I used to be a surface mount assembly tech in the UK, just wanted to give some advice on solder paste application using a stencil. Lay the paste down the shortest edge of stencil and using a thin but fairly stiff piece of metal drag the paste "sausage" across the stencil in one go(using firm but steady pressure), the paste should appear to roll as its going. Repeatedly wiping across the same spot as you do in the video is causing excess paste to go through the stencil, which can cause messy joints and bridges.

@jwshields 2 роки тому
If you don't mind me asking, do you have any pointers for resources of how to do stenciling? I have absolutely no experience in this area and am just exploring the ideas and trying to grok it. To be less vague with my question... What does the general process for designing & producing the stencil that you use to lay down the solder paste on the board? Would it be something simple-ish like a desktop CNC and some thin metal to route out the holes for the paste, or am I not big-brained enough for this and missing something obvious?
@alanjrobertson 2 роки тому
@@jwshields personally I just took the easy route and ordered a stencil when I was getting my PCBs made - was dead easy based on the gerber files. Only thing I learned was to make sure I didn't have too big a stencil (I found the JLCPCB website was a bit confusing on this bit).
@jwshields 2 роки тому
@@alanjrobertson gotcha. I figure if you're ordering PCBs, a stencil to come with it would be a typical sort of addon, that's good to hear.

Instead of this, we can also go the traditional way to fill a pan with sand and use it as the hot plate, we can also easily change the size of pan to accomodate a larger PCB size. Well we do have problems of temperature control but a potential solution for those who do not want to use it too often.

I think it would make more sense to make the DIY version as two boards, one control board and one just as a heater. That way you only need to replace the heater board if it gets damaged over time.

If you don't have a hotplate yet, but you got a heat gun laying around: Just put one edge of the board in some kind of holder, like a vise or alligator clips and heat it from below. This has the same effect as a hotplate. I have soldered like this very often, no damage to the backside of any board yet and you can control the heat intuitively with your hands. Only downside is that the heating isn't as uniform as with the hotplate and large boards will warp a bit because of that. Largest one i have soldered this way was 100x70mm^2.

I have a challenge for you @greatscott. While shopping for solder paste, I noticed that the low-temp melt solders come in different temperature ranges, and I thought... this could be used to do double-sided PCBs, which are usually not possible for hobbyists at home. You would first do one layer with the higher temperature solder, allow it to cool, and then do the other side with a lower temperature solder. Unfortunately I have not had the opportunity to try this yet, but I think it would be a fun project for your channel.

Hi Scott, long time follower here without an e.engineering background. My favorite way to do hot plate is based on a workshop i followed at a MakerFair in Rome: It uses a ceramic heater portable stove (one with a glass surface) at low power, and once temperature is reached, to maintain the pub there until the lead melts. It is also a method that costs less than 25euros, and can fit the biggest pcb you can think off or as many as you want at the same time, with great results, but it requires you to pay more attention. The dream would be a hacked PID version of such a heater with an external temperature sensor (like a 3DP thermistor) . Maybe a cool subject for another video :)

Actually the project reminds me of the first heated bed develloped by Prusa for DIY 3d-printers. The same principle. As I tinker a lot with 3d-printers, I have a lot old controller boards - some years ago cheap printers from creality used soldered allegro drivers and 8 bit controllers, so one of the first upgrades was to swap the board. So I have some of these creality board, which are practicly an Arduino Mega with Mosfets, conectors for temp sensors, display etc. So I think it would be best just to adapt the software for the Arduino Mega and the I/O-Ports Creality (and others) use for bed-heating and just make a PCB for heating. With controller being seperated from the heating PCB, it is also possible to make it more easy to solder bigger PCBs aerea by area, if you use sinking screws for mounting the heating PCBs, as you can keep the controller out of the way. Also I always like to reuse old obsolete hardware instead of buying new one.

I thought these kind of plates before just as a support helper, to bring it to a closer heat Temperatur and then use hotair or the soldering iron finally for easier assembly.. But I was also thinking of re-using a 3D printer heat build plate 🤔
@bracco23 2 роки тому
most cheap 3d printers don't really go high enough. I used mine to loose the glue while opening a phone (great use), but cheap ones usually stop at like 100-110 C, which is not enough for resoldering. maybe spare parts for higher-end machines like the vorons or the e3d toolchanger might be better.
@bobcarter6143 2 роки тому
If the ATMega is in such short supply then why not rework the pcb for an ATTiny1604 or similar which are available at the moment. They basically have a 328 core just with reduced pinout count, and the schematic for this only uses 9 active pins.

I remember you have come up with a solution: hot sand with normal frying pan. Of course the hot plate can make the soldering process easy to control.
@felipemakara5067 2 роки тому
If the temps envolved are so "low", another option to build a bigger heating area is to use a 3D printer bed heating PCB. They usually are 22x22cm, but there are bigger options. This would also solve another previous comment about separating the PCB from the heater
@bbowling4979 2 роки тому
I was wondering about this. I typically don't drive my printer build plate above 100C. I wonder if it could get to the 160C needed here.
@felipemakara5067 2 роки тому
@@bbowling4979 With enough power and thermal insulation, anything can be done (including burning the electrical insulation :P), but unless you can "pump a few more volts" from your printer's power supply, I agree that would be pretty hard to reach.
@archerbob6847 Рік тому
Did you put solder paste over the entire PCB? Edit: Scratch that, I now understand you use a stencil. Could you make a hotplate with a thermoelectric peltier, as they can go up to 200 C and I think you said your solder reflows at 160 C. Does the MHP30 already use a peltier?
@glowing_kitty 2 роки тому
Really cool project, the DIY version!:) separating the heater PCB from the control unit and using a better accessible microcontroller (maybe some cheap ESP chip) which can also be programmed more easily would be nice improvements.

I also recommend you using a halogen reflector above the PCB, also controlled by the temperature probe. Usually in the industry a pyrometer is used, but for the average DIYer a pyrometer is way too expensive to be purchased.
@galaxya40s95 2 роки тому
I presume the reflector is for additional heating from the top side?

@reddot8701 2 роки тому
I think buy doesn't win, 100$ for a small plate like that is quite expensive. DIY is a much better option, also you can improve the design by using an external heater that will support a lot of charge/discharge cycles. Over all thanks for the video, like Always super interesting 👌😁
@davidjohnston4240 2 роки тому
I have the small plate and it's great when it works and doesn't occupy lots of bench space which I appreciate. If I had a big board full of 0402s I would be paying for manufacture, so it seems to be enough for my purposes. I'm not doing aluminium boards though where a bigger plate seems like the right thing.
@Azraelfromgamefax 2 роки тому
I have a really small design suggestion for the DIY version: If you remove as much of the border as possible on two or even three sides, it would be possible to place 2, 4 or even more next to each other, creating a bigger platform. Maybe a niche use-case, but you can see how expensive the large reflow surfaces can get. Actually, that ties in with Collin Bardini's comment about making the control circuitry separate.

My sons graphics card burnt a mosfet (plus fuse and regulator). I quickly learned, even at 450c hot air reflow station is no match to get anything off the PCB. Normal PCBs bubble at such heat but graphics cards can take way more (just like your aluminum LED board). I wonder, would this be a possibility for such removing? FYI it’s double sided for extra difficulty!!!
@k.o.0 2 роки тому
@@maxhouseman3129 It a 1000 dollar graphics card, so I had nothing to loose trying. I held 450c (my max on hot air rework station) for 20 minutes. The chip did not budge, but it melted the top plastic but the metal pins were bound beyond anything I have ever seen. The board was completely unharmed nor any surrounding ICs. I understand why not a single electronics repair shop was willing to do this swap for me. Its not your typical clean board fresh install and the super small size of the IOR 3553 is already challenging enough considering all the contact points. Sadly this beast of a card is destined for the landfill.

@harkrits.nagpal6505 2 роки тому
I had created a similar project a couple semesters ago for my industrial instrumentation and control course. However, I used an old broken portable iron and a ss relay along with the Arduino and OLED display. It worked great for soldering PCBs and also used pid control. Turned out so good that my teacher had me make 2 more for the lab to use instead of the commercial ones with full sized irons 🙂🙂. So I greatly recommend using that for the heating surface and the rest of the pcb heater as control. Only problem is that since mains electricity is involved, only experienced people should try it 🙏

Nice DIY hotplate and board layout. Thanks for your test - its impressive to see how "easy" it is to create such a hotplate by your own. Another idea could be a sheet of aluminium with drilled in heating pipes from 3D Printers. As a solution in between I am using the ET-10 Heat Table, which I bought for around 40 bucks. It's heating area is 10x10 cm. Heating time is not the fastest but it's doing well. Thanks for your GreatJob! :)
@MarkusBurrer 2 роки тому
A few years ago I used a mini oven and a controller called Reflow Kit from Beta Layout, formerly known as PCB Pool. That works well too and allows to solder lager PCBs or multiple PCBs at once.

Interesting video. I watched couple of videos of PCB based hot plate and this one looks promising as a product. A slight disadvantage is you will need a lower melting point solder but shouldn’t be an issue for hobby projects. Didn’t know JLC started offering 3D printing. Will have to give it a try next time I order PCB’s from them.

@bskull3232 2 роки тому
Please do not use SnBi solder. They create fairly unreliable joints, and as shown in your video, parts tend to shift before being soldered. I won't go through the detailed mechanism here, but just don't use them. Use SAC305 or at least SnPb whenever possible.

In a college course I first learned to solder SMT components using a cheapo kitchen hotplate. It worked pretty nicely, but without temperature control (just a dial from "low" to "high") it resulted in some well-toasted silkscreen on the underside.
