Oppo Factory tour: How a smartphone is made from start to finish! By Mr. Phone

Hey the theory from Mr. Food and a couple of days ago, we actually got an awesome opportunity to go and check out opus factory here in Noida and, of course, we had a lot of fun, but what we also made sure was that we documented as much of the experience as we could so that we could share it with you guys so without any further ado, let's jump into the video and see how smartphones are really made. So we start by wearing the factory safe coats along with the cap, so that the contamination stays on the down-low. Now we were all dressed and ready to move towards the first part of the factory, but before that we did pass through this cool filter room which actually be ionizes us and makes sure we are not carrying any charge which could potentially damage circuit boards. Now, the first thing that happens in the process of building a smartphone is the PCB assembly. This is where the heart of the smartphone is put together.

The chipset that I am the wrong everything. That being said, the PCB printing is something that still happens in China. That is also one of very few parts of the process that India is trying to catch up with now, once we have the printed PCB in it goes into this contraption to keep it in place and then goes into the machine where we have different smaller components like resistors capacitors. Well, let's connect the points mounted onto these boots now I say boards, because this, while it might look like a bigger board, this is not the thing that goes inside a smartphone is actually for PCBs in one contraption, which is later cut. Of course, we will show you that process as well, but now, once the board goes through these machines and all the basic parts of the basic electronic parts are put onto the board.

Now we move on to the solder machine, where all the connection and solder points are put on, so that the latter coming parts like the RAM, the ROM, the chipset, can be put onto these boards. This all actually happens quite seamlessly. There's this long line of machines that you can see and all of this happens in one go now I've been to a few factories and what I can tell you are that not all factories are as automated as this now after the RAM, the chip set, the ROM is all set up. You also have other parts of the phone going into this, and you can see this almost machine gun like cartridge going into this process, where you can see the SIM card slots, the micro SD card slots and all different shields and everything going on to the chipset to make it a complete piece. Now, once this chip set, then the board comes out of the other end.

There is VI happening, which is visual inspection, which is also something you'll see, quite often in a factory where a human technician actually checks for any loose connections or anomalies, and then moves it forward for board cutting. So once we have all the PCB boards cut, we go into the next phase, which is a testing phase, and that begins with in relation of software onto the board. Now, while a lot of factories have people manually doing this, the oboe Factory has massive machines, doing the jobs seamlessly for them. This is truly an example of how human workforce is easily being replaced by machines. Now, once the software is loaded, PCBs are checked for different things like signal strength to t3g, along with appropriate electrical signals, sent to different parts to make sure that all of them are working right.

Also, in this process, there are moments where you have to use glue. Of course, when you don't have that much space to put in a screw or anything and for the glue leaks, there is a very cool UV inspection which shows you if there is any leakage in the glue as well. Now we move on to the phone's assembly step. This is where you see a sudden jump in the number of humans working. This is where the phone starts to take shape.

So you start with the display unit, which then takes in different connectors, the headphone jack, the cameras both front and back and, of course, visual inspections of VI every few processes. Now, after all of this is kept, we have the battery going onto the phone, we have the shield's going onto the phone, and we also have the back cover. Finally going on, and now after all, this is done. We go to the next round of testing where everything from smaller parts to things like calling speaker, headphone jack, display, touch cameras. Everything is tested using a meticulously designed phones, which makes sure that there are the least number of faults.

Also in the PCB assembly, is done when you have to cool down that whole PCB board OPO actually uses liquid nitrogen to do that, which is a very cool process now, while the assembly line only does this testing there is a whole another test lab which does the more interesting tests. And, yes, you guessed it right, I'm talking about the freaking drop tests and tumble tests and extreme weather tests, etc. These tests also include pressure tests at different weights in different situations. For example, as you can see here, this over phone is actually kept inside a jeans material, and it's simulating a situation where your phone is in your jeans, and it's putting different kinds of pressure to make sure that the phone still works. There is a dust test as well, where a dust storm of sorts assimilated which the devices then tested in you, have also more detailed camera tests, which Minister phone should take some inspiration from as well, where they test different objects, numbers alphabets and colors from different sizes, different distances to make sure that cameras are not just working but also performing well.

There is a very cool UV inspection which shows you if there is any leakage in the glue as well. Now in this cool testing room apart from the drop tests and everything that you see, the ports are also tested, so the USB port is actually tested with a demo port that goes in and out almost ten thousand times. So that's how many times the phones are tested, they're, not your phones, but randomly the phones from the batch are tested. You also have the tumbling machine. The tumbling machine also rotates 75 times for each phone.

What that means is that your phone goes from one end of the tumble box to the other end almost 75 times, which is massive. So even if, after that, your phone survives, then of course it is quite durable. Now what you're thinking is right are all our devices going through all these tests? Well, no! Well. What happens is that once the device assembly is completed, and you have different cartons, so what the engineers do is actually take one carton out of a batch or two cartons and check phones at random. Then, even if one phone is found, faulty then the whole batch is rejected, and you go back, and you get all of this through further inspection.

Now, once all of this is done, the devices from the batches that were approved are actually provided, IMEI numbers and then the phone's go for packaging, with, of course, your chargers cables and covers, and everything that you get inside the box, depending, of course, on the device. Now, even after all, the packaging is done, and the boxes are packed and sealed. There are supervisors who will check devices at random to make sure that there are no faults and, as I said earlier, this happens everywhere, even if one of the devices is found fault, even if one of the boxes is maybe missing, a component is missing a case maybe or a sim tool, then the whole box or the whole batch is rejected, and it goes back to inspection again now, one of my favorite parts of the packaging is when the Box goes through the shrinker and the plastic just wraps onto the box, like else to Apple products. And finally, you have that packaged box that comes to your home when you buy a smartphone, so that was the end of the factory tour. We had a lot of fun as you, so we of course saw firsthand how smartphones are made, and this is really encouraging to see how the manufacturing process is happening at such a large scale here in India, and what I can also tell you are that there were other plants also being made very close to this.

What that means is that more and more manufacture is going to be happening out of India out of this country and will soon probably be the manufacturing hub of the world. So with that I leave you to it. Thank you so much for watching this video. Let me know what your favorite part was of this factory tour and, of course, I will catch the next.
