Digital circuit experiment box is the basic experiment teaching instrument of â??digital circuitsâ?�, â??pulse circuitâ?� and curriculum designing. When this product was designed full considerate the experimental teaching characteristics, elaborate design, product performance is stable and reliable, and experimental flexibility, to cultivate the students' practical ability, is an ideal teaching equipment in the higher colleges, the professional technical institute, the technical secondary school. II. Equipment system function Digital circuit experiment box motherboard is made of 2 mm thick printed circuit board, front printed with components graphic symbols and relevant attachment, opposite is printed wire, and welding related components, the motherboard set with several high reliable multi-function chips socket (20 P, 40 P), several high reliable silver coating long copper tube, for insert resistor capacitor, diode and the transistor, etc, and with the universal bread board for insert all kinds of components. Also has more than 200 high reliable locking type turn fold socket (and internal connect with integration piece socket, silver coating long copper tube and fixed devices), when as an experimental connection, test points, experimental wiring, just take lock plugs wire to connect with each other. The experiment box adopts high-strength aluminum alloy, appearance is elegant.
