一般集成电路分为以下几种: 一、常规集成电路:这类集成电路一般为单列或双列管脚,且管脚间距也不太小,安装与更换都比较容易。二、贴片式集成电路:一般分为双列和四周排列两种,目前此种集成电路的更换使初学者十分头痛,广泛应用于VCD等电器中。 General integrated circuits are divided into the following categories: First, the conventional integrated circuits: Such integrated circuits are generally single or double column pin, and pin spacing is not too small, easy to install and replace. Second, the chip integrated circuits: generally divided into double and arranged around two, the current replacement of such integrated circuit is a very headache for beginners, widely used in VCD and other electrical appliances.
