Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing.

[0016] A mobile phone PCB board encryption method, comprising the following steps:

[0017] A. Set at least one barcode encryption pattern and at least one laser code encryption pattern on at least the TOP layer or BOTTOM layer of the PCB;

[0018] B. Use a scanning gun to write the encrypted information of the two encrypted patterns into the FLASH module of the PCB board;

[0019] C. Carry out a combination operation on the above two encrypted information, and save the binary value of the operation result in the user data area of ​​the FLASH module.

[0020] The present invention also includes anti-counterfeit encrypted silk screen shading patterns on the PCB board; the present invention also includes: step D. reading the above-mentioned calculation results from the FLASH module, and writing them into the EEPROM; the TOP layer and the BOTTOM layer of the PCB board A barc...

Abstract

The invention relates to a mobile phone PCB encryption method comprising the following steps: firstly, at least a bar code encryption pattern and at least a laser code encryption pattern are arranged on the TOP layer or the BOTTOM layer of the PCB; secondly, the encryption information of the two encryption patterns is written into a FLASH module of the PCB respectively through a scanning gun; and thirdly, combined calculation is conducted to the two pieces of encryption information, and the binary number of the calculation result is saved in a user data area of the FLASH module. By adopting the method, a better encryption effect can be achieved.

Description
