Practice has proved that a medium-sized optoelectronic devices by conventional means to test its system cabling needs at least a day or even more, through the automotive wiring harness design and testing system to test, in seconds to complete the test task, one can imagine The intervention of automatic automotive harness test system is a revolutionary breakthrough in the system cabling detection technology.

Due to the different chemical structure of polymer materials, the ability of radiation polymerization is very different, and some degradation-based, while others are mainly cross-linked. Even if the cross-linked polymer, along with the backbone of the fracture, it must be strictly controlled the irradiation time and irradiation dose, so that the degree of cross-linking in the best condition. Cross-linked polymer, with the irradiation time and dose increase, the degree of crosslinking increased.

The system consists of three major parts: a space satellite satellite constellation, ground control part of a ground monitoring system and user equipment part of a signal receiver. Global Positioning System (GPS) is a high-precision, all-weather and global radio navigation positioning and time-based multi-functional system that has been established with the development of modern science and technology. It is located at a distance of more than 20,000 kilometers from the earth and sends a steady stream of positioning signals to the Earth. Any receiver on Earth can receive information about the position (longitude, latitude, altitude) time and movement of the receiver as long as it receives signals of more than four satellites. System with high precision, all-weather, high efficiency, multi-functional, easy to operate, widely used and so on.

The determination of automobile wiring harness design branch assembly sequence is based on the analysis of automobile wiring harness branch attribute and its impact on the system performance. Engineering on-line assembly of automotive wiring harness is generally the first trunk after the branch, and according to the needs of the special requirements of the harness branch to be properly adjusted. According to the assembly principle of the branch after the main trunk, the branches of the harness are automatically sorted layer by layer. Then, the designer of the craft adjusts the assembly order of the branch with special requirements according to the experience and expertise, so as to obtain the optimal assembly sequence of the branch.

The chrome-plated steel strip and tin-plated steel strip soaked in hydrochloric acid for 20 days, the results of chrome-plated steel strip only a small amount of corrosion, and tin-plated steel serious corrosion, the film is completely off, the chrome-plated steel strip and tin soaked in 75 Degrees in 7 days, the results of chrome-plated strip no change, that is, there is a good compatibility, and the tin-plated steel tape appears a lot of small polymer bubbles, and the longer the soaking bubble, that is, Under this condition, the compatibility between the tinned steel strip and the beam paste is poor.
