拆修长城巨龙1250W电源

xyy0518

这个电源二手买的，服役四五年了。几天前使用过程中，突然听到机械硬盘磁头停转复位声。打开我的电脑，哦豁，机械硬盘消失，重启也没解决。还以为是机械硬盘坏了，拆开机械硬盘清理了一下，量了一下也没看到主控板哪里有烧的，然后装回去又能用了。至此还以为只是机械硬盘玄学问题，几小时后，使用过程中电源突然熄火，重新开机也是主机亮一秒就熄火了，这时候就知道电源有问题了，拆开量5V没输出，都说这个DC-DC电路的控制芯片容易坏，所以就开始动手了

拓扑结构 LLC + DC-DC
电容 智宝450V270U *2 缩水后的版本



拆DC-DC小板，这个板子巨难拆，引脚又多，又分开，吸锡器吸不干净，最后堆锡用风枪480度吹了一分多钟才干下来的。换都换了顺便把另一块的也换了，省得哪天又趴窝了



APW7073 PWM控制芯片 + 2上管 + 2下管
管子型号0603GH， 30V100A



MOS底下和PWM芯片底下都打胶了，这MOS拆一个坏一个，不高温又取不下来，想拆下来测好坏的，板上测不准



换上立创买来的管子和某宝买来的开关芯片，顺便把输入电容换成16V 2200UF的，另一个16V 470UF懒得动了，原本是两个16V 470UF的。装机测试，先飞线，免得装上不工作拆下来又满头大汗。




成功秒杀，立省几百
