A self-protective safety circuit board

Abstract

The invention relates to a self-protective safety circuit board, which adopts a new hidden self-destruction structure scheme, and realizes the protection of circuit traces and various circuit components (4) on the upper surface of the substrate body (1) through a protective cover (3) , to prevent criminals from obtaining the circuit components (4) and circuit wiring positions, at the same time, introduce a high-voltage power supply (2), and design each trigger to be distributed between the protective cover (3) and the substrate body (1) At each position, the conductive sheet (7) in each trigger part and the corresponding two wires (8) contacts constitute the displacement detection trigger core, and when the protective cover (3) is attacked and moved, it can drive one of the trigger parts The displacement of the middle insulation rod (5) makes the conductive sheet (7) contact and communicate with the corresponding two wires (8) contacts, that is, the connection realizes the impact and burning of the key circuit components (4) by the high-voltage power supply (2), and completes the self-disconnection. The protection reduces the implementation cost of the circuit board self-protection structure, and effectively improves the safety of the circuit board self-protection.

Description

Technical field [0001] The present invention relates to a self-protection safety circuit board, the circuit board belonging to the technical field of self-protection. Background technique [0002] May be referred to as printed wiring board or printed circuit board, the circuit board layers according to the sub-divided into single-sided, double-sided, and multilayer wiring board three broad categories, the circuit board is the most common electronic apparatus, each of the electronic components on the board are performing work function of the electronic product is obtained, since the actual application, a circuit board with electronic components in the specific operating data, and the circuit board with the circuit traces transmitting data signals, which tend to be when criminals to steal important data pathways, so how the data protection circuit board from being stolen, became a circuit board protection on the one hand, on board means of protection they use a self-destructive way...

AI Technical Summary

Problems solved by technology

[0002] Circuit boards can be called printed circuit boards or printed circuit boards. According to the number of layers, circuit boards are divided into three major categories: single-sided boards, double-sided boards, and multi-layer circuit boards. Circuit boards are the most common devices in electronic equipment. Each electronic component on the circuit board performs work separately to obtain the functions of the electronic product. In practical applications, the electronic components on the circuit board run specific data, and the circuit traces on the circuit board transmit data signals, which often become Lawbreakers have a way to steal important data, so how to protect the data in the circuit board from being stolen has become one aspect of circuit board protection. Self-destruction procedure, this is an existing general protection method, but the existing protection structure is complicated, the implementation cost is high, and the actual self-destruction method often has secondary damage, such as electric sparks, explosions, etc., the risk factor is too high
