华为40W冰糖充电器拆解
看完了华为40W冰糖充电器的开箱和实际充电测试，下面就进行拆解，一起来看看这款充电器内部的设计和用料如何。
首先撬开充电器输出侧面板，充电器内部灌胶填充，增强散热能力和耐候性。
切开充电器外壳，取出内部PCBA模块，交流输入采用弹片接触通电。
为PCBA模块供电的触点特写。
使用游标卡尺测得PCBA模块长度约为31.74mm。
PCBA模块宽度约为26.98mm。
PCBA模块高度约为27.07mm。
清理掉PCBA模块的灌封胶，算上平面变压器，整个PCBA模块共由四块PCB焊接组成。
在模块背面焊接固定一块散热片。
散热片通过焊接固定，塑料片穿过主板上的开槽，起到绝缘作用。
充电器顶部一览，与变压器一体的塑料绝缘罩用于高低压隔离和支撑作用。
