The utility model relates to a PCBA test fixture support, in which the three corners of the floating plate are connected with the base plate of the frame through a reset part, the sinking platform on the top surface of the floating plate is provided with a PCBA board to be tested, and the floating plate is provided with an array of through holes corresponding to the test points of the PCBA board to be tested; and the bottom of the frame plate is provided with a rectangular box body with an opening on the top surface. The front panel of the box body is provided with a button switch, the middle part of the back panel of the box body is provided with a transverse waist-shaped through-hole, the right side of the waist-shaped through-hole is provided with a junction seat, one end of the junction seat is connected with an external load, the other end of the junction seat is connected with a button switch, and the bottom surface of the chassis is provided with a number of test probe caps, each of which is tested. A probe is arranged inside the needle cap, and the probe is one-to-one correspondence with the through-hole on the floating plate. The structure design of the utility model is reasonable, even if the PCBA test has problems, sparks and explosion flashes occurring during wiring are all in the space composed of the bottom plate of the frame and the box body, thus ensuring the personal safety of the operator.

技术介绍
PCBA是英文PrintedCircuitBoardAssembly的简称,也就是说PCB空板经过SMT上件,再经过DIP插件的整个制程,简称PCBA板,PCB中文名称为印制电路板,是电子元器件的支撑体。在PCB出现之前,电子元器件之间的互连都是依托电线直接完成的,PCB出现之后,电子元器件便集成在一块基板上,在批量生产过程中,由于设备和操作员等各种因素影响,不能保证生产出来的PCBA都是完好的产品,这就需要在生产末端加入各种设备和测量工具,来测试所生产的PCBA,以保证出厂的和设计的PCBA各种规格和参数完全一致。PCBA测试主要是利用测试工装模拟真实使用的情况,即对所有PCBA的外部设备接齐,使其工作于各种设计状态,去获取各个状态的参数,来验证PCBA功能好坏的一种测试方法。现有技术的PCBA测试工装大多是将测试探针帽直接固定在工装浮动板上,探针帽的一端插上探针与被测PCBA的测试点相连接,另一端则是直接焊线在探针帽上与外部设备相连接,存在以下技术缺陷 ...
