Analog circuit teaching experimental box

Abstract

The invention discloses an analog circuit teaching experimental box. The analog circuit teaching experimental box is configured with a plurality of analog circuit modules mounted and welded to independent PCBs corresponding to the analog circuit modules correspondingly; the PCB of each analog circuit module is at least provided with a wiring layer and a screen printing layer; the screen printing layers comprise top face screen printing layers and / or bottom face screen printing layers, wherein the top face screen printing layers and / or the bottom face screen printing layers comprise circuit principle connecting screen printing layers for a teaching circuit connection schematic diagram, and text symbol screen printing layers for teaching recognition of used component information; the circuitprinciple connecting screen printing layers are used for teaching experiment showing of the electrical connection principle of all components constituting the analog circuit modules; the multiple analog circuit modules comprise but are not limited to main panel modules; and the main panel modules are provided with various sensor circuit interfaces, extended function boards and a plurality of independent circuit debugging units with an independent circuit function and / or a multiple independent component function. Application skills of circuit design operational capability, component recognition capability and design capability in circuit layout of students are improved, and the experimental teaching effect is improved.

Description

technical field [0001] The invention relates to a teaching experiment box, in particular to an analog circuit teaching experiment box. Background technique [0002] Usually in the teaching of circuit experiments, analog circuits occupy an important part of the teaching. Many digital integrated circuits are also integrated on the basis of analog, and their peripheral circuits also need many analog circuits to cooperate to complete the circuit functions; while in the teaching of analog circuits, usually After teaching students the basics of circuit principles, then set up analog electronic technology experiment courses for students to achieve a deeper and more stable teaching effect on analog circuits. In the teaching of analog electronic technology experiment courses, usually many schools use breadboards or Self-made experimental equipment to carry out the teaching courses of analog electronic technology experiments; although the breadboard is simple and versatile, it takes a...

Problems solved by technology

[0003] The present invention solves the disadvantages of existing analog electronic technology experiment teaching courses, which are not conducive to better cultivating students' basic skills such as circuit design ability, component recognition ability, and component design and application in circuit layout. Even after taking the analog electronic technology experiment course, there is still little gain in the application skills of analog circuit design, which is not conducive to better achieving the effect of experimental teaching, so it can better cultivate and improve students' hands-on ability in circuit design. , component identification ability and basic skills such as the design and application of components in the circuit layout, the analog circuit teaching experiment box to improve the experimental teaching effect
