Problems solved by technology

[0002] With the improvement of PCB board copying and copying technology, well-designed product PCB boards are easily copied, cloned and stolen, causing huge losses to the company and customers
like figure 1 As shown, in the existing PCB board manufacturing technology, the via hole is composed of a via plate and a hole, and the connection hole between the two layers is treated with sinking copper, that is, there is copper in the via hole, so as to connect the upper and lower layers. The PCB board of the structure is easy to be stolen due to the mature technology

Embodiment

[0011] In the original PCB board production (more than two-layer board), when designing and laying out the PCB, for the via holes or pads, when doing encrypted wiring, the connection of the via holes between different layers is punched but not plated. Copper treatment, other cover oil, plug oil and appearance process are consistent, so that the appearance of the PCB encryption hole produced by it looks the same as the appearance of the PCB board via hole with connection relationship, but the actual two-layer circuit has no physical connection relationship, thus misleading plagiarism There are physical connection errors in the process of copying the board. After multiple encryptions on the PCB, the production or debugging process of the plagiarist fails, which greatly increases the difficulty of plagiarism, thus giving up plagiarism or greatly prolonging the plagiarism process.

Abstract

The invention discloses an encryption technology for preventing copying of a PCB. In original PCB production, wiring design is carried out on the PCB; pseudo via hole encryption is carried out on via holes or bonding pads; a pseudo via hole comprises a hole plate and the via hole; the connected parts of the via holes between different layers are punched; copper plating treatment is not carried out in the via holes; and no physical connection relationship is formed between upper and lower layers of lines. The encryption technology is mainly applied to large-medium electronic product producing and processing enterprises for preventing products from being imitated and copied by third-party companies, does not increase the manufacturing cost of an original product, and only improves and adjusts an existing PCB board-making technology; the scheme is simple and feasible; and the possibility that the product is cloned or copied is effectively avoided. The encryption mode is simple, effective, high in invisibility and suitable for a mass production technology and product encryption and improvement.

Description

technical field [0001] The invention relates to the field of PCB boards, in particular to an encryption processing technology for anti-copying PCB boards. Background technique [0002] With the improvement of PCB board copying and copying technology, well-designed product PCB boards are easily copied, cloned and stolen, causing huge losses to the company and customers. Such as figure 1 As shown, in the existing PCB board manufacturing technology, the via hole is composed of a via plate and a hole, and the connection hole between the two layers is treated with sinking copper, that is, there is copper in the via hole, so as to connect the upper and lower layers. The PCB board of the structure is easy to be stolen due to the mature technology. Contents of the invention [0003] The object of the present invention is to provide an encryption process for anti-copying PCB boards, so as to solve the problems raised in the above-mentioned background technology. [0004] In orde...
