Introduction of welding accessories and cleaning tools

   In daily life, almost everyone has a mobile phone, and we often encounter the problem that the mobile phone cannot be turned on. There are many reasons why your phone won't turn on. This time, let's take a look at the problem that the iPhone X cannot be turned on due to excessive startup voltage.    First of all, first check the appearance of the motherboard, the motherboard is not deformed or damaged by water. Then connect the motherboard battery connector to the DC power supply . Start the board with tweezers. The starting current is greater than normal. Judging from this, the fault may be related to the 17 power rails of the PMU output.          We remove the motherboard and need to confirm whether the fault is related to the upper or lower layer. Place the motherboard on a dedicated heating platform. When the platform temperature reaches the set temperature, carefully pick up the upper layer with tweezers. Continue to remove the lower ...

   When using a mobile phone, it is inevitable that the mobile phone cannot be turned on due to some problems. It may be that the book machine cannot be turned on because the current is too large. Let's take Iphone 11 Pro max as an example to learn how to fix the problem that it cannot be turned on due to high current.    High current is one of the common problems in mobile phone repair. Due to the large number of components involved, it is difficult to detect damaged components. This is where thermal imaging cameras are needed, which are often used to quickly detect faulty parts.     LINCSeek SuperCam thermal imaging camera mobile phone motherboard PCB fault detection, use the one-key power cable to power the motherboard, adjust the display mode to thermal imaging mode, and enable the software quick check function to detect faulty parts. Simple operation to quickly help find faulty parts    First, lift the screen and disconnect the battery....

    There are different types of microscopes, each serving a different purpose. Some are suitable for biological applications, while others are used in educational institutions. There are also microscope types available for metallurgy and studying 3D samples. In this article, we will learn about microscopy together.        First, let's understand what a microscope is. A microscope is an optical instrument composed of a lens or a combination of several lenses, and it is a sign that human beings have entered the atomic age. Microscopes can be divided into the following four categories according to the microscopic principle:       Polarizing microscope, Optical microscope, electron microscope, digital microscope, etc.    Now let's take a look at polarized light microscopy: Polarizing microscopes are microscopes used to study so-called transparent and opaque anisotropic materials, and have important applications in science and engi...

   There are some common mistakes you make when you get your hands dirty with your phone, and here are some common phone repair mistakes and great ways to fix them. Check these few things to see if you've made a mistake while repairing your phone or laptop.    One of the main things you should do when you start repairing your phone is to disconnect the battery.

  When we repair mobile phones by ourselves, we will use welding tools.Soldering involves only a few simple steps, but perfecting a sodering job is no easy task. At this time, rework station and welding station, which one should we choose? In this article, we'll learn about these devices and how they can help you better understand their use.   First, let's understand the rework station. A rework station,also known as a hot air rework station, What are hot air rework stations and what are they used for? When people refer to a rework station, they usually mean-a table specially drilled into its top surface. It can be used for desoldering or soldering electronic components, it only comes with a heat gun. The following is an example of ATTEN ST-862D heat gun rework station.   ATTEN ST862D intelligent digital display rework station is used for PCB chip welding repair. Its advantages are: LCD screen displays working temperature and status, and realizes visualization and human-...
