摘　　要：主要研究小型化77GHz毫米波雷达天线板制作。采用4种不同材料混压,解决4种材料的涨缩带来的层间、芯板之间对准度问题。另外,还解决了距槽近距离的过孔渗药水污染槽底金面问题,在内层单元内设置定位基准点,再以电荷耦合器件(CCD)自动对位钻孔实现高精度通孔及背钻;采用树脂刀片划片实现高精密外形切割;设计了凹槽式钢网及钉耙式刮刀,完成槽底元器件自动化贴装,实现贴装小型化天线阵列。This paper studies the miniaturization 77 GHz millimeter wave radar antenna printed circuit board(PCB).The main contents include the following aspects:using four different materials to make the PCB,and solving the problems of interlayer,core board and the PCB alignment caused by the rise and contraction of the four materials;solving the problem of the gold surface of the bottom of the tank contaminated by the permeable liquid water close to the groove,setting the positioning reference point in the inner unit,and then using charge coupled device(CCD)alignment drilling to achieve high precision through-hole and back drilling;using resin blade to achieve high precision shape cutting;designing the grooved steel mesh and nail rake scraper to complete the automatic placement of the components at the bottom of the groove to achieve the effect of welding.Finally,a 77 GHz millimeter wave radar antenna is achieved.
