Here’s a quick tip. One of the number one mistakes that people make is this, what is this? This is pinching to zoom on your phone, no matter what phone you have, whether it has optical zoom or it doesn’t, one of the worst things that you can do is do digital zoom, you’re losing megapixels there, which means you’re going to lose quality. How do you solve this? Simple. You move your feet, you move forward, you move back, you get your composition right and that’s how you start doing this which is digital zoom.

Hello and welcome to this next video on mobile repairing. In some of the earlier videos, we tried understanding the different chip components which are placed on a PCB. In this video, we will try and understand how we can do the reballing of an IC onto a mobile PCB. In order to do that, first of all we need to understand what is reballing. Reballing is a method by which we can place an IC onto a mobile circuit board or a PCB. Many times the IC components may not function properly. This could be because the soldering joints that are underneath that, may probably not be proper.In those cases we will need to do reballing. Now let's understand the two types of ICs first of all before we start reballing.
This IC is called a lead IC and we've seen this IC in some of the earlier videos. This is called a lead IC because there are leads on both the sides or pins on both the sides, which are usually soldered on to the PCB on both the sides. Sometimes, there are also ICs- lead ICs which have pins on all the four sides. Sometimes they have it on two sides and sometimes on one side. Depending on the IC, you need to use the soldering iron to actually place the IC onto a mobile PCB. You can use a micro- soldering iron, if the IC is really small. And these ICs can also be removed using the hot air gun or SMD. These ICs are very easy to place on the board because it just requires a micro-soldering iron to solder it on the sides and you can use the hot air gun or SMD to remove it from the mobile PCB. However in order to do this, you will need to practice a lot before you can do it very clearly.
The reason why we say this is done better by practice is because the tips of these ICs are very minute as you can see in front of the screen. These leads are very minute and therefore you need to be very careful when you're soldering them onto the PCB. These leads should not touch each other, otherwise it can result in a short circuit in the IC. So you need to ensure that you solder it appropriately with highest level of focus on ensuring that each lead is uniquely soldered on to the PCB. And that's why you need a lot of practice to place these kind of ICs. The other type of ICs are called the ball ICs. Ball ICs as we have seen in one of the earlier videos typically have small balls or circular tips which are placed at the bottom of the IC.
So this is the front of the IC, if you turn it around you will be able to clearly see the balls there. These ICs don't have any pins on the side and as you can see now- the small minute balls are very clearly visible. These are the points which are actually touching the PCB and thereby the entire communication that happens on the IC happened through these small connecting tips. Now many times these connecting tips may disappear due to continuous usage or may not have been placed properly. Sometimes, they can even break if the mobile falls or is handled inappropriately. So, in order to replace these ICs, you need to do a process called reballing through which you can replace these balls at the back.
To do the reballing, you will need a BGA kit- it's called a Ball Grid Array Kit. So ball grid array is essentially because of these small balls which are placed in a kind of a grid, in an array- that's why it's called a ball grid array or a BGA kit and this BGA kit comes with a base plate, which is what you see in front of you.
The base plate is where we place the ICs. There are specific shapes which are given for each of these IC's depending on the size of the IC. So depending on which IC you need to reball, you can pick up the right IC and place it at it's right mould and once you place it in the right mould, the IC will fit in appropriately there and you can do the reballing process. For example let's try out one IC and see where this places. Now if you see, each IC will have very specific positions where you can place them. For example this IC can be placed only in this position and this is exactly the position where it'll fit in tightly. Once you place the IC in the base plate, you can then use the reballing process to recreate the ball grid array that you will see on or that we saw on the backside of the ICs.
Now in order to create these ball grid arrays, you will need specific outlines for each of these. These are all called BGA plates. BGA plates are nothing but a metal plate which has holes in specific patterns. These holes or these patterned holes are similar to what you would need to create at the back of the IC. So for the respective IC, you will need to identify which pattern works well and works appropriately and then you need to use that pattern to be able to create the reballs or create the BGA back on the ICs. Whenever you pick up a BGA kit from the market, you normally get some standard plate- such as these. These standard plates will have the designs for most of the common ICs which are placed in mobile phones. But as you keep practicing, if you get more mobile phone for which you may not have designs- you can always buy those designs independently in the market. So these are different types of plates with very different designs, depending on which IC and what type of BGA or ball grid array that you need to create at the back of the IC.
Apart from these tools, we will also need a paste.This is a different kind of paste. This is not what we use for soldering or this is not flux. This is called a reballing paste, which is very different- looks very different and this is the paste that we will need to use while we are doing reballing. We should not touch the other types of pastes that we say in earlier videos such as the flux. They can create problems on the IC and in the entire reballing process. So you need to ensure that you use the right reballing paste and this is also available as part of the BGA Kit. So when you're buy a BGA kit, you will always get a reballing paste along with a BGA kit as well.
There's another paste that we will be using, which is called as the soldering paste. Soldering paste is what create those.. creates those tips on the IC. So as you can see- this is a soldering paste and these are the soldering tips..this is the paste that creates soldering tips on the back of the IC. And you will learn how we use this soldering paste in the next video.
So these are pastes that you will need to use while you're working on reballing. You may need apart from that.. you may need the thinner and a stone which can be used for cleaning the tip of the soldering iron. Apart from that the SMD is another tool that we will be using to create those points on the mobile PCB. Apart from these, from a tools perspective- there are two small tools that you can see. First one is a cutter. So when we're making an IC, or when we're making the points on the IC- sometimes there could be overlap of the soldered points. You can use the small knife to ensure that the soldering is kept intact and there is no connectivity between two or three different points, when you're making them on the back of an IC. The other tool on the left hand side that you see is essentially used to apply the paste onto the reballing plate or the IC. So whenever we have a mobile which has come to us for repair, you will try and identify the fault with the components that we saw earlier.
Most of these components are easily removable, replacable- such as the head piece, the speaker, the ringer , the mic or any of these aspects. Whenever we are.. those are.. whenever the problem is not with any of those components you may need to go deeper to try and trace the circuitry in the entire mobile device and when you're checking the circuitry- you may come across smaller components where there could be problems. Sometimes, while you're tracing this you may eventually find out that the problem is with a particular Ic and that IC is not functioning properly.
You may need to do the reballing process. It could also be doubtful for you in that process because sometimes the IC may not be touching properly. So, even in the case of doubt you can try and use this whole process of reballing to remove the IC from the board. Once you remove the board.. the IC from the board, you can check the backside of the IC to see whether the BGA or the ball grid are in position. If the ball grids are not clear, if they have ruptured off- you may want to use the reballing process to ensure that we do the reballing of the IC. So behind the ICs you will use this entire plate on top and create those ball grid arrays at the back of the ICs and replace them back on the PCB.
So this is the process of reballing We've tried to understand a little bit about the tools and equipment that are required for reballing in the IC. Going forward in the next video we will try and do the reballing of one of the ICs and help you understand how you can do reballing at your own workshop. Thank you very much..

hey guys come here from 9:00 to 5:00 Google and Android n has been available in the form of a Developer Preview now for a few weeks and it's already into its second preview and part of this upcoming major software update is the baked in ability to have two apps side by side on the same screen this is otherwise known as split-screen multitasking here's how you use it now right now there are a couple of methods for activating the split screen a method one is what I call drag-and-drop within Android n when using any app or even on the home screen you can tap the app switcher icon that's the square one on the bottom right of the screen and most phones this launches the familiar card based multitasking window now we tap and hold one of these apps that you'd like to have on screen then drag it up to the top half of the screen or to the side and once you've done that the app will take up the top half of your display assuming you're holding it in portrait and not in landscape mode the bottom half will show the app switching screen then you tap on the second app you'd like to have on screen and then you have two apps running side by side on the same screen now the second method requires a little bit more in terms of digging into the software but once it's been activated it's actually a lot easier now first what you have to do is enable system UI tuner within the settings menu this means you need to swipe down from the top of your screen until the full notification shade and quick settings tiles are on display now you'll notice a settings cog in the top right hand corner you press and hold this icon for a few seconds until it starts spinning once you let go you'll see a pop-up alert on screen for a short while telling you system UI tuner has been added to your settings options one system UI tuner is active you go to settings system UI tuner then hit other and then tap the toggle to enable split screen swipe up gesture once this is active you can simply swipe up from the app switching button that's the square one again and it'll launch the split screen mode now once activated apps take up an equal portion of the screen as default with the split right in the middle you can adjust where the split goes just by touching and holding the middle split and moving it wherever you want up and down the screen what's more as hinted at previously this split-screen mode works in portrait or landscape so if it's active you rotate your phone so that it's horizontal and the split screen apps arrange themselves side by side instead of above and below each other when the split screen is activated you'll notice that the app switching single square icon that we've been talking about has turned into two parallel rectangles now if you want to while it's active you can actually hide the apps by pressing the home button what this allows you to do is it allows you to select the secondary app that you want to run in split screen mode just in case the one that you want didn't show up in the initial options now like with launching split screen mode there are a couple of methods for canceling it too first off you can press and hold the split screen app switching icon second you can just drag the app splitter until it's right at the top or the bottom of the screen filling your display with a single app now of course split screen mode has been designed predominantly for tablets but it means that you can drag and drop content or copy and paste text from one app into another without having to keep on switching between two different apps it certainly can make you more productive especially on a tablet now it's important to note that because this is beta software for now the methods and exact UI may change over time but we'll be sure to update the post linked in the description box if anything changes majorly to impact you by the time the software is available as a public release it's also worth noting that apps need to have split-screen compatibility so some apps will support it and some won't at least initially I've been camera mat cam Bunton on Twitter and I'll see you again soon you

Hello, welcome to Robojax's ESP32 tutorial. in this tutorial we are going to learn how to steer the pedal motor from the interface of your phone or mobile device or browser to any predetermined angles by simply touching will be controlled via your Wi-Fi will have an unlimited number of pressures buttons. each will have their own angle direction and speed. you can get the code for this by clicking on the link below the video in the description that will do take you to www.robojax.com/learn/arduino let's get started. my name is Ahamd Shamshiri. I present this tutorial from Canada. stepper motor is widely used in many applications and mechatronics automation and other industrial applications and I worked on it for some time pedal motors GS car Arduino and other ways to control it. inclusive direct connection or via Wi-Fi and Bluetooth. and I wrote this code for this car so you can control and steer the pedal motor to any desired angle. you just press the push button and the car will go to that corner.
If you are I use a separate video for Arduino here you can set the angle where you can set the direction and you can set the speed for each pushbutton and there are no limits as long as you do not device let you push more buttons you can have, and you can send them to that corner. now in this – really you will be able to control the hiker car with an unlimited number of pushes buttons via Wi-Fi from your phone or your computer or tablet browser. so you have different push buttons each has a separate angle, direction and speed. just touch it and the car will go to that corner and with that speed and direction.so you can have a personal angle with different directions and make you faster can tap it directly on the screen and just send and the car goes there direction. and it is available for ESP 32 and esp8266 d1 mini and NodeMCU Wiring explained let me now explain the wiring.
I connected five volts external 5 volts to make sure you have this module jumper it is connected. and now the 5 volt comes here in the red side is connected to positive it is linked to the negative. for the cars you can not make a mistake as it is linked here for the module I linked like this IN1, IN2, IN3 and IN4 I have some extension connected man-to-woman cable it comes so and in this this IN1 is connected to pin 13, IN2 is connected to pin 12 there is an empty space in between, because this is ground and then IN3 is connected to pin 14 and IN4 is connected to 27, so they are all ordered inside with the exception that there is a ground GND. and these pens are marked exactly as they are here as you can see here G 13 ground G 12 G 14 g27 on this modulates exactly the same g13 ground G 12 14 27 you can change it to any other digital pen as you like. if you die wiring diagram for it is available as part of my Arduino course at udemy.com.
If you want to learn Arduino, I have a course for best sellers udemy where you can learn Arduino from the ground up with hundreds of projects all course material library codes wiring diagram all available in one place. the link for more new courses below this video in the description. Code Explained the original code that I started it from this example if you click on file examples and then scroll down until you see this area is for ESP 32 and it line the distributor web server and then advanced web server. I took it and it changes drastically. due to some of the inclusion and some features so I did not change it easily, but I changed the code heavily. let me now explain the code.
For the code you need to set the pins here. Pins 1 and 2 & 3 & 4 it's for the pins we have in here for these input pins. so i have set pin 13 12 14 and 27. and then because we want us to have four push buttons has four angles, it's for 1 2 3 and 4 so it's these values you see here to 360 and then the next line the direction and in the next slide we have the direction CW, CW is for 360 s CCW is for 270 CW is for 90 and CCW is for 20 and the next one is a speed factor for which it is 10 for the 360 is 1 for 270, so there is to be in line with each other. and if you want have more just add a comma here and if you want you get for example 287 degrees it clockwise capital CW does not put small CW you will get error. and then a speed factor let's say 2 and then the last one here it's a value that when you click it sends the car and it's just text.
"car sent to" and also for the for the last one also a comma and within the double quote the reason why I stated all because sometimes the location refers to something and for example it place where something moves and you call it 5 degrees and here you call it turn if I turn it off I do not know what to do so to enable you to adjust it I prepare it in full. it's the rest the extent you see here is this in this "in" is here and then a speed factor is this text I prepare and allow them to customize it because people use different languages for many other languages or sorry other purpose you need to be able to change it and this angle is this text and then direction did not use it here comma velocity is this text and then send is this text.
So all these texts that you see here is customizable and here including this stop this stop is here so everything you see with the word title you can customize it. SSID and u Wi-Fi password this is a route I use manual I will turn it off. I do not worry if you know the password. if you must explain the full code available as part of my Arduino course by udemy.com.
The link to my course at Udemy is below this video. Demonstration: desktop computer here is the ministry. the first thing you need to know if it's inside the code connected to my Wi-Fi router for this tutorial it's called Robojax. so your computer should be connected to the same as you can look here it is linked to the Robojax otherwise it does not work. so this is the first condition. afterwards if you upload the code on the series monitor it now opens and press it sets the push button here like the reset press the button as soon as you press it, it will press the IP address for you so you can get this IP address, but in the majority of networks you can type it directly http: // roobjaxESP32, so I'm copying it right now by pressing Control + C and I'm going also show you that one that IP address.
So i'm going to open a new one tab and then control V. and press Enter. so it now comes from this module because the module now acts as a web server. and it is defined so first try this on your phone http: // robojaxESP32 if it does not work then use this IP address. this IP will be different from network to make networks, whatever your ESP 32 shows here will be your address. and late i also show you the one that will make it work. let me open a new tab plus paste and enter. and here through the IP address we get and go through it the robojaxESP32 we can also get this. and now here is the demonstration. currently the car is stopped and these are the available values for the four corners with a set direction.
The speed I do not want to show the speed here, but once you click it for example for 270 so it goes when i start turning the car pressure and it shows you the in angle it shows the direction it shows the speed factor you have set the code and it also shows you the time it will take to complete. with this speed this angle. for example if i go for 90 it will work clockwise 90 degrees somewhere. in here, but because the speed factor is 4, it will take 4 seconds to complete the section.
And these 20 degrees clockwise from here maybe up to here and it took 2 seconds because a speed factor was 10. and now look at 360, so it will happen come back to the same place and it will take 40 seconds because the speed factor is set to 10 for 360 if you set it to 1 it will take 4 seconds and 2 3 4 and because it is 10, 10×4 = 40 40, so it takes 40 seconds to complete and I also show you the counter here at the top. so you can see It. and and when it's running at all at the moment you can just click and stop it. so the stop is always available go for 360 and it runs a lot now slowly, but you can stop it at any time. does not matter. so you can move take it anywhere you want and stop it and then stop all this stuff angles apply for example this 90 means that from this point it is now 90 and with the clockwise direction it goes here.
So it will go 90 degrees in that direction and from here to 90 is now here and all these angles are with respect to the last known location. so this way you can move it and stop it where you want. Demonstration with custom values I also worked a lot on this section too, and it was very time consuming so that you can set your angle, for example, you can set it 450 degrees clockwise and speed factor of 1. now it's 450 so 360 plus some extra corner in goose 450 and I put her in before that means it was normal 450 the angle was the factor was 1 it will take 5 seconds to complete angle within 5 seconds. and if I do it 2 that will be the same angle for 10 seconds now it's much slower and it shows her that timing. Demonstration on mobile and here I have now connected my phone to the same Wi-Fi Robo connection and here I enter the IP address I just showed you 192.168.1.100 192.168.1.1 here is now a demonstration with a mobile device let us send it to the clockwise 270 degrees, so that it displays exactly the same as a larger display.
90 degrees and stop it at any moment. 20 degrees and you can go also in here and let me insert 289 degrees here clockwise and go. the push button does not display the text here properly. I need to see why. and now if i go with 360 I state that the speed factor of 10 so it would take 40 seconds before that would happen let's go for it. now it shows that it takes 40 seconds and here also in the same way as you can depart with a speed factor the one means the fastest speed and as you increase the number the speed will slow down down, for example if I set it to 2 and I go 360 clockwise or maybe clockwise it will take 8 seconds because one means four seconds and two means it will complete eight seconds. and the calculation also shows there Caption typed and corrected by Ahmad Shamshiri on June 19, 2020 in Ajax, Ontario, Canada I thank my guests from Patreon.com I did my part to help you learn.
