Description
The present invention relates to a kind of protecting structure of package of integrated circuit, particularly a kind of energy protection packaging box can not be subjected to improper external force and invade, and guarantees the design of integrated circuit internal document fail safe.
In the design field of some electronic circuits; how with formula design desire to reach the software of function after; be burned onto the individuality that constitutes single-chip control in the integrated circuit; the formula that wherein includes mostly is the source code of not desiring known to the people, therefore in order to reach the purpose of protection integrated circuit, method the simplest, with low cost; be exactly outside integrated circuit, to make an enclosure; by airtight box body, prevent the source code in people's pirate integrated circuit without permission, and leak business opportunity.
Yet general enclosure only is simple box body, and any people that scheming arranged can utilize the mode of destruction, such as, electric drill, the mode of beaing, only otherwise injure integrated circuit, all can therefrom steal source code.Obviously general Package boxes can not satisfy actual privacy requirements.Therefore, for avoiding this type of taking place with the situation that external force is directly destroyed, the preservation measures of enclosure is essential.
Main purpose of the present invention, provide a kind of protecting structure of integrated circuit seal apparatus box, it is provided with a plurality of paired circuit for detecting plates in enclosure, etch transverse line on the circuit board on upper strata, the lower circuit plate then is a vertical line, should be vertically and link between transverse line and with the electricity group of zero ohm, to constitute the protecting net of criss cross, and be linked to by socket in the slot of surface-mounted integrated circuit, this integrated circuit utilizes software to select a detecting pin to export a signal in random number mode, and whether signal is finished an electric loop and judged whether package of integrated circuit suffers the improper means intrusion in the circuit of aforementioned circuit plate by this.
Another object of the present invention is for making package of integrated circuit still have the preservation measures of detecting when not working, a powered battery is provided, make integrated circuit constantly send detection signal, when avoiding integrated circuit not work by improper intrusion.
A further object of the present invention is when detecting when infringement, and this integrated circuit promptly locks and includes source code, makes other people can't pirate.
Another purpose of the present invention is to make this circuit for detecting plate constitute more fine and closely woven protecting net, can adopt at least one group of above pairing, makes the result of detecting more accurate, all can't set about to destroy no matter reach in each corner of enclosure.
For achieving the above object, the invention provides a kind of protecting structure of package of integrated circuit, it is characterized in that it includes: at least one group of stacked circuit for detecting plate, each group circuit for detecting comprises that an etching has the circuit board of vertical line, and etching has the circuit board of transverse line, should vertically and on the transverse line be drilled with the hole, power supply resistance binding constitutes electric loop, and binding site is integrated into socket; And a surface-mounted integrated circuit, which is provided with socket and peg graft, and have at least a pin to be communicated with this socket for above-mentioned socket, detect electric loop with output signal and whether disconnect.
Now the embodiment shown in conjunction with the accompanying drawings describes structure of the present invention and function in detail.Wherein:

Symbol description:
10 upper cartridge bodies, 11 screws, 12 screws, 20 lower box bodies, 21 screws
30 surface-mounted integrated circuits, 31 integrated circuit components, 32 sockets, 33 batteries, 34 points of contact
44 ground floor circuit for detecting plates, 45 second layer circuit for detecting plates
The 4th layer of circuit for detecting plate 48 socket of 46 the 3rd layers of circuit for detecting plate 47
As shown in Figure 1, this enclosure includes upper cartridge body 10 and lower box body 20, and it is assembled in the both sides of surface-mounted integrated circuit 30 respectively, with 31 sealings of the integrated circuit component on the surface-mounted integrated circuit 30, this upper cartridge body 10 is provided with corresponding screw 11,21 with lower box body 20, is locked on one by screw 12.
Shown in Fig. 2 and 3, the inner edge surface of upper cartridge body 10 of the present invention and lower box body 20 is provided with a plurality of circuit for detecting plates 40, these circuit for detecting plates 40 are provided with in paired mode, etch transverse line on the last layer circuit board 41,42 of lower circuit plates are vertical line, should vertically and on the delivery position of transverse line impose boring, and link, constitute the protecting net of criss cross with the resistance 43 of zero ohm.(as Fig. 2 and 3) for instance, last layer circuit board 41 etch many transverse lines (as V with a determining deviation
1, V
2, V
3...), 42 of lower circuit plates mark many vertical lines (as H with a determining deviation etching
1, H
2, H
3...), and at the edge of circuit with the resistance 43 of zero ohm be connected upper and lower layer circuit for detecting plate 41,42 laterally and vertical line, and constitute mutual conduction and become the protecting net of checkerboard.
For taking the All Ranges that two-layer circuit for detecting plate 41,42 can't reach packaging body into account, therefore, can use more multi-layered circuit board stacked, to constitute bigger and close protecting net for improving the level of saving from damage.Below in conjunction with Fig. 4 four layers of circuit for detecting plate are explained again.
As shown in the figure, in second implemented, the first circuit for detecting plate 44 can etch odd number bar transverse line (as V
