Automotive radar printed circuit board

The automotive radar printed circuit board (HDI) is designed with high-tech electronic technology. Although the overall performance of the system is improved, it increases the complexity of the system and puts forward newer, higher and stricter requirements for the maintenance of the system.

Modern automotive radars (such as multi-function phased array guidance radar, multi-function phased array measurement radar, pulse-guided radar, etc.) have a long service life, while the life cycle of modern electronic products is quite short. The most advanced electronic technology products, these products may be obsolete within a few years, and some HDIs that support the maintenance of radar systems may also be obsolete. It is not enough for the system to only have a certain number of HDI spare parts. Some HDIs will be used in the system. If there is a fault in the middle of the road, it needs to be replaced and repaired. The repair of HDI requires spare electronic components and devices, as well as advanced supporting HDI fault detection equipment and repair equipment, which makes the automotive radar maintenance support system more complicated.

The maintenance system of the automotive radar HDI is one of the main tasks of the radar maintenance support project. The automotive radar maintenance support project is a system engineering that meets the maintenance and support requirements of the system. Its main purpose is: when the automotive radar is put into use The feasible methods at that time were applied and continued to develop to ensure the timely, appropriate and economical maintenance support for automotive radar equipment. The main maintenance tasks of the automotive radar HDI maintenance system are: repair the HDI that has failed in the use of the automotive radar system, restore it to the original technical state, and continue to put it into use. The basic content of repairing the HDI includes fault detection, fault isolation, electronic Disassembly and re-installation of components, troubleshooting test, inspection qualification test, restoration of original appearance, etc.
