The functional test after circuit board assembly is generally called FVT (Function Verification Test, functional verification test) or FCT (Function Test, functional test). The full function test of the whole machine is carried out in order to catch out all possible defective circuit assembly boards...
挑战:通过PXI 控制板卡和LabVIEW软件,构建一套比较完整齐全的PCB板的功能测试(FCT)系统,利用该系统可实现对音频视频以及各种静态参数(电压、电流、频率)的综合性全自动测试,对于新开发生产的PCB板,工厂无需频繁更换测试硬件,只要添加制作一个测试夹具,重新连接线路,利用LabVIEW开发编写测试软件即可。
If something stops the whole PCB from working, it can be quite a painful experience for the customer. The FCT simulates the operating environment of the circuit board and helps you prevent any errors you might struggle with in the future....
