电子产品“使用”和“放置”哪个寿命更长??
2022-07-25 17:21:00 【夜半少年】
电子产品“使用”和“放置”究竟哪个寿命更长不能一概而论。
首先说“使用”,“使用”造成的老化多见于较大功率/能量密度的部件。比如显示、供电部分。另外储存部件通常也有使用寿命限制。大部分民用的晶体管电子设备正常的使用寿命是接近线性的,不管你怎么用,总使用时间没太大差别。
然后说“放置”,氧化、腐蚀是最大的问题。另外顺便提一下非电子行业比较少知道的,电路板上焊锡还会极缓慢地“长胡子”。放置的环境对氧化的速率影响非常大,一般家庭的环境,南方的气候电子产品的放置寿命比正常使用还要低,北方会好很多。另外长期放置电池过放也会造成失效。所以,根据气候环境条件,放置不用的设备建议1-3个月使用一次,然后充满电。
此外,如果湿度较大,比如南方的“回南天”,长期不用的电子设备甚至可能在通电时直接因凝水烧毁。
