The invention discloses a hot melting detachment prevention dynamic token and a detachment prevention method of the hot melting detachment prevention dynamic token. The hot melting detachment prevention dynamic token comprises a shell, a circuit board used for storing information, and a battery. The shell comprises a shell body and a cover body used for being buckled on the shell body, and further comprises an elastic sheet. The battery is arranged between the circuit board and the elastic sheet. The circuit board, the battery and the elastic sheet are arranged in the shell body. The shell body is arranged on the side close to the elastic sheet. A protruding hot melting column is arranged on the side, facing towards the elastic sheet, of the shell body. The shell body penetrates through the elastic sheet through the bolt melting column and is welded to a through hole of the circuit board. According to the method, when the hot melting detachment prevention dynamic token is detached, the circuit board is cocked, the elastic sheet is separated from the circuit board in the position of the hot melting column, and therefore the circuit board and the battery are separated. The power outage effect is achieved for the circuit board and the battery through a simple detachment method, and therefore integrity of sensitive information stored in the circuit board is improved.

The invention discloses a FPC soft and hard combination board sandwich pressing carrier, which includes a tray, which is made of magnetic metal, and a hard board placement station for placing hard boards and a plurality of soft boards for placing soft boards are arranged on the tray Placement station, the bonding areas of multiple soft boards are superimposed on the corresponding hard boards; magnetic steel sheet, the magnetic steel sheet is set above the soft board and connected with the tray magnetically, and the soft board is fixed on the soft board. The board is placed on the station; the cover, the cover is set above the magnetic steel sheet, the bottom of both ends of the cover are equipped with magnets, and are magnetically connected to the tray through the magnets, and the cover is also provided with multiple for Spring pins for pressing the joint area of ​​soft board and hard board. The invention is suitable for the production of rigid-flex boards with a hard board in the middle and a plurality of soft boards on both sides. The structure is simple and the operation is convenient, which greatly improves the production efficiency and yield of the rigid-flex board and reduces production costs.

The invention provides a method for manufacturing an anti-radiation EEPROM. The memory includes devices: storage units and high and low voltage transistors of peripheral circuits. It is characterized in that the manufacturing method before the formation of the source and drain of each device is different from the ordinary manufacturing method. : The dielectric ONO layer used for the isolation between the floating gate and the control gate in the memory unit is used as the side wall of the high and low voltage transistor gate of the peripheral circuit at the same time, that is, the material of the side wall of the high and low voltage transistor gate is changed, by The silicon oxide film in the conventional manufacturing method is replaced by a composite film of silicon oxide and silicon nitride. The method of the present invention makes full use of the existing common manufacturing method, does not add additional process steps, only by adjusting the gate oxide growth sequence of the low-voltage transistor in the peripheral circuit, so as to ensure that the structure and electrical performance of the high-voltage and low-voltage transistor devices involved are consistent. Change, and improve the anti-radiation performance of the device, thereby improving the anti-radiation performance of the entire EEPROM. The method of the invention is suitable for mass production.
