自然界绝大数昆虫也和人体一样是导体,有一定的导电能力。如把电视机摆在蟑螂等虫子时常出没的地方,一旦它从机壳后的散热孔爬进机壳内,爬行在密密麻麻的电路板元件之间,它那具有导电能力的肉质体若正巧搭接在某些关键元件焊接点或引出线之间,就会造成一定程度的短路。 有的人看完电视关机后,总要过一段时间再罩机,认为这样有利于电视冷却,可以更好地保护电视机。其实,这是一种误解。 电视机关机后,热空气开始冷
The vast majority of insects in nature and the human body is the same conductor, a certain degree of conductivity. If the TV set cockroaches and other bugs often infested place, once it climbed into the chassis from the cooling vents, creeping in the dense circuit board components, its conductive ability of the flesh body if it happens to take Connecting some of the key components between the soldering point or lead-out line, it will cause a certain degree of short circuit. After some people watched the TV off, it would take a while before the re-capping machine, that this is conducive to cooling the TV, you can better protect the TV. actually it is a kind of misunderstand. After the TV is turned off, hot air begins to cool
