Embodiment 2

[0033] Example 2, such as image 3 As shown, optionally, the equivalent impedance network is programmable, the programmable control interface is connected to the corresponding interface of the PCBA, and the antenna module control software is implanted in the chip, and the equivalent impedance network is controlled by the antenna module control software, During the production test, its impedance characteristic is equal to the impedance characteristic of the impedance encryption module when it works normally.

[0034] The invention also discloses a device and method for designing, producing and testing wireless products of anti-copying boards. Firstly, a plurality of batteries are connected in parallel to form a parallel battery pack, and then a plurality of parallel battery packs are connected in parallel to form a battery string, and then a plurality of batteries are connected in parallel to form a battery string. The wireless product design and production test device and meth...

Abstract

The invention discloses a wireless product design and production testing device and method of an anti-shoveling plate, and belongs to the technical field of testing. The device comprises a body PCBA, an antenna module, an equivalent impedance network and a production testing module, the antenna module comprises an impedance encryption module, a wireless radio frequency port and a radiation module, and the two ends of the impedance encryption module are respectively connected with the wireless radio frequency port and the radiation module; the body PCBA comprises a chip and a radio frequency port, is connected with the wireless radio frequency port of the antenna module through the radio frequency port, is further connected with the production testing module through an equivalent impedance network, and is further connected with the production testing module through a control line. According to the present invention, an independent hardware encryption chip is not needed, only the impedance encryption module is needed, the simplest design of the module is realized by adopting the discrete components and switch tubes, and the cost is much lower than that of the hardware encryption chip.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to an anti-copy board wireless product design and production testing device and method. Background technique [0002] Wireless network communication equipment is widely used in contemporary times, and sales are also rising steadily. However, electronic products, including wireless products, are more or less at risk of being copied. Copy boards generally copy electronic products with superior hardware performance by separating and measuring PCBA components, analyzing and taking pictures of PCB layer by layer, and restoring PCB. The behavior of copying boards is difficult to prevent under the current technical conditions, and it will cause great disadvantages to excellent hardware design companies. [0003] Generally, the hardware anti-copy board needs to be implemented by implanting hardware keys and encryption chips. [0004] The traditional anti-copy board method is implemented ...
