苹果13ProMax不充电

顾客描述:手机插充电器没反应，然后手机重启后电池电量显示1%检测:电池电量一直显示百分之1，电池弹窗，没有测试充电，拆机拿电池检测仪能读到电池数据，更换电池还是显示电量百分之1，判断充电ic损坏，搭电漏电两百多。维修过程:加热平台开170度，热风枪350度辅助分层，由于没有使用此型号的加热平台模具，导致主板没有固定晃动，从而导致封城时间过长，使用热成像发现充电ic发热，更换单板测试充电正常，贴合后发现没有基带，哦豁翻车了。维修后续:先是借来了中层测试架，又勉为其难的打了一圈中层阻值(明年图纸会打阻值神器让你爱上打中层或者整个CPU所有角位阻值)，发现PCIE_GPO_AP_TO_BB_PERSTL这条线路短路，使用钨钢打磨笔打磨中框露出中框过孔铜柱，使用烙铁烫中过孔铜柱，恢复正常阻值后重新贴合修复成功。经验:有很多中层加时间久了之后，很容易有的角位是短路的，有时候买的打磨板中层有的角就是短路，一定要经有测中框阻值的习惯维修

结果:已修复

Apple 13promax does not charge

Customer description: The mobile phone plug -in charger did not respond, and then the battery power displayed after the mobile phone was restarted: 1%detection: the battery power has been displayed by 1%, the battery pop -up window, no test charging, the disassembly and the battery detector can read the battery data, If the battery is replaced, it still displays 1 % of the power. It is determined that the charging IC is damaged and the power leakage is more than 200. Maintenance process: The heating platform is 170 degrees, and the hot air gun is 350 degrees auxiliary layers. Because the heating platform mold of this model is not used, the motherboard is not fixed, which causes the city to be too long. The charging of the single board test is normal. After fit, I find that there is no baseband, oh the rollover. Follow -up of maintenance: First, I borrowed the middle -level test rack, and it was difficult to make a circular to the middle resistance value (next year drawing will be used as a resistance artifact to make you fall in love with all corner resistance values of the middle layer or the entire CPU). In the short circuit, use tungsten steel polishing pen to polish the middle frame to expose the middle frame over -hole copper column. Use the soldering iron to perfle the copper columns in the middle of the iron. Experience: After many middle -level plus a long time, it is easy to have a short circuit. Sometimes the horn in the middle layer of the grinding board bought is short circuit. Be sure

Result: Fixed
