[Music] [Applause] [Music] [Music] as a freshman in repair industry are you clear on what kind of tools are needed for a logic board repair today rail lab will share with you our choice so let's get started first you need a motherboard of course there are two types of motherboard here one is just for handwork practice without CPU add not the another can be booted up to test current voltage and diode value and next I'm going to show necessary repair tools on the repair platform this is power supply test cable connected with DC power supply to motherboard to power it on we can observe the booting current immediately on the DC power supply so that we can roughly analyze the issue this cool guy is repair station integrated three-in-one DC power supply hot air gun and soldering iron go ahead to use this digital multimeter to measure the current voltage and diode value if some connectors are not easy to measure this eye bridge will be helpful one side is connected to motherboard another side connects two corresponding spare part then measure the voltage or diode value at the middle pet what's more the normal reference value is also marked the average is available for all models a set of eye bridge includes front and rear camera connector charging connector display connector next show you some repair work tools please pay attention on this multifunctional PCB holder it's not only used for iPhone motherboard but also Huawei and Samsung an iron piece is assembled at the bottom to ensure that the holder doesn't slide during working besides there is a card slot used for chip glue removing I'm sure you all know this is the microscope absolutely needed in motherboard repair these are the two types tweezers we commonly use stainless steel material super fine super hard tweezer tips are polished and the handle as man it is used to remove flex cable and disassemble components when repairing the motherboard the length and tweezers are more convenient to use for big hands this is the brush which is used for cleaning motherboard with long service life this is cutting nipper mainly used for cutting the shield this golden tool is sculpture knife handle with double ended aluminum alloy material non-slip design blades can be installed on both ends of the handle with different blades installed it can remove black glue pry up chips and clean bonding pad in addition it is watched with different size of blades based on the size of chip or pad this one is solder wick and this is rosin before cleaning tin with solder wick coat some rosin it will be more effectively when the rosin is a necessary material in rosin method which is commonly used for a large current issue this is Cooper wire when the circuit is open or the pad is dropped the Cooper wire can make it to be completed circuit there are two types of copper wires with different diameter the 0.
02 millimeters is used to connect the open signal circuit and dropped pad the 0.
1 millimeters is used to connect the power supply circuits such as backlight power supply circuit and camera power supply circuit what is solder flux it is used for soldering or de-soldering components sometime assists cleaning bounding pad if the insulation paint of the motherboard circuit or pad is peeled off which may cause short-circuit this one will be helpful you of igloo you just need coat a little and it's also used to fix cooper wire after jumping wire then we need use the UV dryer lamp to solidify the UV glue for five to ten minutes here are two types of solder paste which are commonly used on mobile phone repair this one is low melting temperature solder paste its melting temperature is 138 C it is used for soldering work of iPhone 10 /xs / 11 thirdspace PCB this blue is middle melting temperature solder paste it's melting temperature is 183 C it's used for chips rebelling or bounding pad cleaning now look at this one BGA rebelling stencil which is used for chip ribbing it's with square hole easier to take off the chip after rebooting and it's available for our iPhone models this one is BGA scraper which is used to scratch solder paste from container when dribbling Chimps dust free wiper it's used for clean the display assembly this is heat resisting adhesive tape it is used protect components on motherboard from high temperature this is original iPhone 8 USB cable which is used to restore iPhone and that is all detailed explanation of commonly used phone repair tools looking for a great project to jumpstart your logic board repair career why not try our selected repair kit and equipment set [Music] [Music] you.
