BGA Rework station is called SMD rework station . And it is also called a blower or hot air gun in slang language by technicians even though they are 2 different tools. It is a cell phone repair equipment that blows hot air for removing and soldering any electronic components or IC on the motherboard like microphones, charging ports, etc. Now come back to the topic we will discuss today - How to use  BGA rework station ?     There are some precausions for using BGA rework station that you have to keep in your mind, it's especially essential to set up air and heat in a proper way! Air Setting: You'd better keep the air setting a little above the minimum level. Because it is possible to remove or damage the neighboring parts if there is more air in the period of soldering. Otherwise, if there is no air available, it may lead the coil inside the handle to burn. Therefore, you need to set properly to keep a little bit of air is coming out along with the heat.  Heat S...

With the extensive application of large integrated circuit and super large integrated circuit in the third industrial revolution, welding technology has also been widely used in the electronics industry. The circuit board welding technology mainly uses tin lead solder, and sometimes we need a variety of welding tools to complete a welding job. Such as Anti static Solder Iron, Tin Sucker, Rosin,  Solder Paste , Solder Wire and Hot Air Gun. Now this article will introduce Rosin, Solder Paste, Solder Wire and Hot Air Gun. 1. Welding Accessories When soldering components and pins in the internal circuit board of the smartphone, We need solder wire to connect the component pins to the printed circuit boards. In the welding process, in order to prevent solder oxidation we need flux paste to operate. We usually use flux paste mainly have rosin and solder paste. The following figure is the appearance of flux paste.  Tips: Rosin is used to remove oxides and impurity duri...

Most of the electronic products are afraid to fall, no matter how expensive it is. Okay, maybe Nokia won't. However, today we're going to talk about a case of a problem after the iPhone was dropped. This iPhone 6 was dropped to the ground, and the screen is broken. When turn it on, it shows black screen. When we connect it to DCpower supply , it shows large current. According this, we can know that it is short circuit. Now, we need to fix it. First, disassemble the iPhone and energize the motherboard . The DC power supply displays 1.7V current that is short circuit and the adjustable power supply voltage is pulled down to 3.4V. The whole motherboard gets hot, especially the main power drive chip. Second, deenergize it and measure the power supply of each circuit at motherboard through multimeter , find that the power supply of PP3V0_NAND of EEPROM is short circuit to ground and the resistance data is 0. The test points of PP3V0_NAND are shown in picture 1-1. 1-1 ...

Life is like a box of chocolates, you never know what you're gonna get. It's the same with repair phone, accidentally, you might screw it up. Here is the case. A friend want to fix a iPhone 6, but accidentally the screw hole was penetrated, then he made up wires, but it is not working. Now, Vipprog will tell you how to fix it. 1. Disassemble the iPhone by phone opening tools , then cleaning the screw hole, we found that the two circuits under it are cut into two parts. This situation cannot be settled by scratching PCB to make up lines but to jump wires . We have to use green oil to solidify the jump wires. 2. Finally, we need to paint all the area with added lines green oil . Then we turn iPhone on and test it, all the function can back to normal work. Tips: 1. As many of you do not pay attention to the strength that you use to twist the screws, the screw holes are often twisted through. 2. Usually, although we can scratch PCB to make up lines...

There are many people like to play the phone when they walking and this increases the risk of falling on your cell phone. There is a case which iPhone 6 was dropped in the floor, it can turn on to use, but used for a while or when it in charge, the screen turns white and reboots repeatedly.

First remove CPU and clean the exposed copper on its solder pad. Use UV Solder Resist  to paint the exposed copper and use ultraviolet Light  to solidify it, as shown in picture 1-1. 2. At the bottom right corner, there are missing joints. One of them is the pin to fingerprint EEPOM. Press the pin with multimeter  and there is diode data if we press hard. Thus, we know that the board is disconnected. Doing Jump wire  from the solder pad, as shown in picture 1-2. 3. Solde...

The iPhone 6S Plus has been hit by water, but we had the first aid on it, then we test it, all is fine expect the charging issue. After iPhone dropping into water, it is slow to charge it and later it cannot be charged. Solution 1. Use a tester battery to offer power to motheboard  and test. USB current voltage meter shows that charging current jumps from 0.08~0mA. This phenomenon that there is no current when charging, but shows charging icon is called “battery drains” 2. Usually this issue is caused by the charging chip  cannot output charging voltage. The frequent faulty points are USB chip damage or abnormal working condition of charging chip. Considering the inflow water in it, first we test the charging chip U2300. The charging management chip U2300 in bitmap is shown in picture 1. 1 3. The most frequently damaged parts in iPhone 6 and iPhone 6 Plus are voltage bootstrap capacitor C1402 and inductor L1401. The charging chip of iPhone 6S and iPhone 6...
