Customer Reviews for VEVOR Reflow Oven T962 110V Reflow Soldering Machine 800W 180 x 235 mm Professional Infrared Heater Soldering Machine Automatic Reflow Machine (T962 110V)

Rated four stars due to the great price. Can successfully reflow a 4x4” board using the back mid-center of the oven, as trying to reflow 2 of my boards resulted in unreflowed areas on the outskirts. So I can only reflow one board at a time. Did the heat tape upgrade noted on the tube. Had no bad spell, other then the normal flux smell during the high-temp reflow process.

The oven is great, especially for the price. I didn't do any mods at all. I looked through the vents to see there was no masking tape.I'm flowing SMP-MAX rf ports on boards that were originally made in our factory and have solder mask and graphics. I tried the stock but modifiable profile 8 and I overheated the caps and had to replace a couple of caps. I used profiles 3 and 4 and they actually work although the board still looks a little overheated (the white painted graphics are a little darker) but the caps are OK. I'm including this to show that the oven can really get hot. I want to do some more temp research with a probe and verify the profiles. Existing profiles are working for this tricky project of flowing the center pin (inside) and not burning the caps.The manual is translated literally from Chinese so it is a little funny but you can follow it. There are settings you can change "by yourself".

Greetings,Our company purchased this product when we found out the cost to have a small board assembled was on par - and actually exceeded - the cost of the board. We needed to solder a part which had several 0.725 mm x 0.522 mm (~ 0.029" x 0.021") pads to the board. The pads were on the bottom of the part, i.e., not visible. Challenging, to say the least. We were able to accomplish this successfully *without* a paste mask and without a pick-and-place (we're not necessarily advocating this - just full disclosure). As is said "....your mileage may vary."There were several other blurbs on the web about a foul smell being emitted from the oven on the first few times the oven is used due to masking tape (??!!!) being used internally. The suggested remedy was to replace the *all* of the masking tape with heat-resistant/proof Kapton tape (a bit pricey, but in this application well worth the costs), which we did *BEFORE* our initial use. We also reworked the ground connection, which really wasn't much of a connection due to the attachment point being covered in paint (an insulator) by sanding/scraping a small area under the nut/washer area down to bare metal. Again, this was done *BEFORE* even plugging in the oven. We placed our assemblies to be soldered on a scrap piece of FR-4 before initiating the soldering operation. So far, even with the above-mentioned small pad dimensions, we have a 100% success rate.We can not vouch for the temperature accuracy as we never measured temperatures. Also, due to the small size of our part there was no doubt that heat distribution would be uniform over the area being soldered.I have no comment on the quality control of the manufacturer in terms of unit-to-unit consistency; I can say that we are pleased with the performance of the oven in our application.JimRespireDX/Amalfi Acoustics, LLC

I followed the minor mods for removing the duct tape on the insides, which took about 15 minutes. Beyond that, I haven't had to do anything else like re-flashed the firmware, updating the temperature sensors or anything crazy.So far, we've baked about 50 total boards with this unit and have been very satisfied with the results. We put a board in, press the F1 button and it starts its timed cycle. Are there some confusing menu translations? Sure.. but for $350, compared to paying an assembly house thousands, it's totally worth the money.My only recommendation for use is to run through the burn cycle one time before you bake any boards. That gets everything nice and warm on the inside and makes sure the temperature is pretty even. When we don't do that, we've found some colder spots on the board where the solder didn't fully flow.Highly recommend if you're on a budget.

This reflow oven has many problems out of the box, but if you use UnifiedEngineering's fixes for this oven, including the cold junction temperature sensor, masking tape replacement, and firmware, they can all be fixed and you are left with an amazing product that is unparalleled in value.

I got the 4 element version on recommendation from the internet. The interface is easy and the presets work really well for most of the optical smd sensor that I deploy in prototype instruments.

For the money, this reflow oven is a good value as long as you buy this with eyes wide open. It has a few things that need to be adjusted as soon as you get it, such as removing the masking tape, adding a cold junction sensor, etc. Also, do not expect that the entire drawer will reflow your PCBs. I just use the center and avoid the edges of the drawer as the heating is uneven. Do your homework first. Look up this part number and see all the guides on how to upgrade this oven to a very usable piece of equipment. You can not beat the price.

I bought this with some trepidation after reading about some mods but there was nothing close in this price range. I also bought the 3rd party mod kit. I decided to run it up without the mods just to get a feel for it. It produced a perfect board the first try. Over two dozen boards later it is still running perfectly out of the box. For whatever reason I did not get any adverse smells and checking the boards with the microscope they look fine-the melt is good and far better than my hand soldered ones. One thing to note -- I am not doing "PC mother boards here". Usually 3x3 boards with 402, 0.5 pitch SOIC and larger. I tend to favor leaded solder paste from the syringe or stencil by Chipquik. And usually I use the "set 2" heating curve. I will keep the mod kit just in case I have a failure or want to adapt this to work from a PC but for now I am happy the way it is. What is ironic is that I could buy 4 of these for the cost of one populated board here in the US. I strongly recommend it.

This unit is very sturdy and constructed to last. You MUST replace the inside masking tape with Kevlar high heat resisitive tape. It is well documented on Youtube and on the Internet that this mod is required. I don't know why they build it with masking tape inside. Its pretty easy mod to do. I did not do any of the other modifications others are doing and it works fine. Pick the right temperature curve for your solder paste. Don't try to do very large boards, and stick with using the middle 50% area. I've had no problems. For the money it works and you don't have to DIY building this tool from a toaster oven and an Arduino. It's well worth the money if you are doing SMD, relatively small boards and relatively low quantities.

It's much bigger than the T-962 model, its heat output capacity also allows for a more uniform solder distribution for large PCB brd dimension
