The utility model discloses a manual shielding box, which comprises a box body. The box body and the upper cover are connected by four box buckles. The front face of the box body is provided with a spare interface and an interface. The inside of the box body is provided with an installation plate. The upper cover is provided with two symmetrical handles, and the left and right sides of the box body are provided with a handle. The buckle is composed of a box buckle A mounted on the upper cover and a box buckle B mounted on the side edge of the box body. The shielding box has the advantages of novel structure design, high test efficiency and easy operation; through the signal shielding of the outer box, the sound of the outer shielding layer is weakened, the interference of the outer isolation layer is blocked, and the transmission of the vacuum box is further blocked, so the interference signal entering from the outside is weakened step by step, while being weakened at the same time. After the interference signal also needs to experience the inner shield layer, the inner isolation layer, and the final isolation of the inner box. The interference signal that can enter the inner box has been negligible, so as to improve the accuracy of the test.

技术介绍
对于无线通讯产品生产厂商而言,产品不能及时面市或迅速上量带来的是大量产值和利润的流失,且直接影响后续业务和市场份额的拓展。射频测试工艺通常是手机等无线通讯类设备产线中最为复杂、影响最大的流程,通常也是产线的瓶颈。射频测试站通常由测试仪表、屏蔽箱、测试软件等几部分构成,通常又可分为校准测试、综合测试、天线测试等等几类。由于产能的要求,通常射频测试工艺由多个相同的测试站并行运行。某个或某些测试工位的通过率偏低;产出降低就会导致产线瓶颈、生产成本剧增,而究其原因,大致可分为:产品设计或物料原因、测试的问题(误测问题)、射频干扰等环境因素、测试的不确定问题。电磁干扰/EMI是整个电子领域必须面临和克服的一个问题,一般在无线通讯产品比如:手机、无线网卡、无线路由器、无线耳机、蓝牙耳机、wi-fi、wimax、数据卡、对讲机、RFID等等无线通讯类设备和无线通讯类模块等在进行板测、终测过程中,都是通过使用射频测试屏蔽箱来改善测试环境的。需进一步解释,屏蔽箱是利用导电或者导磁材料制成的各种形状的屏蔽体 ...
