Circuit Board Testing Procedures

The primary components tested can be found below.

Circuit board testing procedures.

The line neutral and earth conductors of the circuit are identified and a measurement from one end to the other end of each is taken. Functional testers used to test full functionality of boards and modules via edge connectors. Most technicians though when attempting to diagnose if a circuit board component is faulty use a volt meter to measure its input and output voltages. It often takes the form of in circuit testing ict and or functional testing fct.

Circuit board testing procedures evaluate several components of pcbs. These components are analyzed in detail to ensure their quality. Electrical testing procedures apply to both initial verification and periodic inspection and include both dead testing and live testing procedures. In circuit testing looks at the functioning of individual components after they are soldered in place.

Board test system pts pcb test system refers to the control of the computer can automatically complete the excitation measurement data processing display or output the test results collectively a class system circuit board test for the completion of the test pcb performance testing based on the analysis of the test results diagnosis and fault location can also be. However many faults can be tracked down by checking connections and performing a visual inspection. As circuit boards have become more complex so has checking them for problems. Keep your hands on the plastic potion of the probes so you don t get shocked.

Computer based automated test procedures can run reliably and consistently with test results captured automatically with high accuracy at high test speeds and with extreme flexibility. A test of circuit board components such as capacitors resistors transistors and integrated circuits can be done to some extent without removing the components from the circuit board. Functional testing provides a final go or no go decision on finished pcbs. These results are r1 r2 and rn.

Each circuit must be tested. In circuit testers performing device level tests on components mounted circuit boards. Testing procedures comprise dead and live testing and visual inspections and will require knowledge and experience of the relevant sequence of tests to be followed in respect of both new installations and periodic inspections. Read the multimeter display for the voltage or.

These components are analyzed in detail to ensure their quality. The red probe goes to the test point and the black probe goes to ground or common. Pcb testing is done once the board is completed. Touch the multimeter probes to the circuit board test points if you re measuring voltage.

This test ensures that all ring final circuits sockets usually are indeed a continuous ring with no interconnects or breaks within it. If you re measuring the resistance of resistors connect one probe to each end of the resistor. More comprehensive testing can be performed on these components when the component is removed.
