说明：  本文详细介绍了制作电路板的方法及步骤. 实验板的功能 这个实验板可以做如下实验： 1．可以进行运算器（加、减、乘和除法）、比较器、译码器、编码器、选择器、分配器和一般组合电路的实验 2．可以进行触发器、寄存器、计数器和一般时序电路的实验 3．可以进行频率计电路、时钟电路、计时电路、交通灯等复杂数字系统的实验 4．加扩展板可以进行A/D、D/A、串行E2ROM和8031单片机等方面的实验
(This paper describes a circuit board production methods and steps. Experimental plate plate function of this experiment can be done is as follows Post-mortem : 1. Operators can (plus, subtraction, multiplication and division), comparators, decoder, the encoder, selectors, Distributor and the general composition of two circuits. Trigger can, register, counter and general sequential circuit of three. Can Cymometer circuit, clock circuit, the timer circuit, traffic lights and other complex digital system of four. Plus expansion boards can A/D, D/A, and 8031 Series MCU E2ROM areas of)
