Bare-board testers check the electrical connections of a PCB before components are assembled. Testing at this stage helps detect opens, shorts and selected insulation or continuity problems associated with board fabrication.
The test uses the intended circuit connectivity as a reference. Probe access, board dimensions and the number of points influence the equipment and program. Fixture-based and flying probe approaches suit different combinations of production volume and product variation.
Accurate test data is essential because the tester needs to distinguish intended connections from unwanted ones. Review the board stack-up, accessible pads and required measurement limits when planning coverage. Testing before assembly can prevent a defective PCB from consuming components and further processing time. Results also provide useful feedback when fabrication issues recur across a batch.
