The PCB manufacturing process includes a final electrical test to verify net continuity and the absence of shorts on the board. In some markets, the increased complexity and variety of PCBs, along with decreasing volumes, have determined an extensive use of flying probe type test systems for electrical test.

Electric Test on PCB with active embedded components
Today it is increasingly common to find in the printed circuit industry, PCB, featuring “embedded” components, either active or passive.
The peculiarity of this product consists in the presence of embedded passive components (like resistences) and active embedded components, like voltage dividers. In order to optimize the production process, board panels are manufactured, containing multiple PCBs. On each PCB, a complete test should be performed for open, shorts, and also to check that the embedded components have the expected values (for resistances and voltage dividers).
Each PCB within the panel, will have its own “electric” barcode, which should be read and stored to achieve a full data traceability. For reduced handling times, the panels are tested automatically.
