Electronic test benches: what are they for?
Electronic board test benches are essential for ensuring the reliability and quality of electronically-dominated products and systems, particularly during the industrialization phase. They enable electronic boards to be tested and validated, their operation to be monitored and their compliance with standards and specifications to be ensured. In this article, we explore the different aspects of electronic board test benches.
Design of electronic test benches
The design of an electronic test bench is a key step in ensuring accurate and reliable test results. A test bench must be designed according to the specific requirements of the product to be tested, industry test standards and equipment durability. The key components of an electronic test bench are testers, mobile probes, interface, acquisition media and FPGAs (Field-Programmable Gate Arrays). An electronic test bench designer needs to be skilled in electronic engineering, PCB design, wiring, mechanics, power, etc.
Manufacture of electronic test benches
The manufacture of electronic test benches is an activity requiring technical skills and extensive experience in the field of electronics. A test bench manufacturer must be able to produce reliable, durable test equipment that meets the highest quality standards.
The manufacture of electronic test benches involves several stages, including design, production, quality control, validation and delivery.
The services of an electronic test bench manufacturer can include test packages, support at all stages of the product lifecycle right from the design stage, manufacture of customized testers, creation of automation solutions, and development of test and burn-in strategies determined upstream of product design.
Functional testing and electrical measurements
Electronic test benches are used to carry out functional tests and electrical measurements to ensure that electronic boards function correctly. Functional tests simulate the normal operation of the electronic board and check that it meets technical specifications. Electrical measurements measure the electrical characteristics of electronic board components, such as resistance, capacitance, voltage, current, frequency and power.
Electronic board validation and qualification
Validation and qualification of electronic boards are key steps in guaranteeing their reliability and compliance with standards and specifications. Electronic test benches are used to validate electronic boards by simulating real-life operating conditions, such as variations in temperature and pressure, electromagnetic interference, vibration and mechanical shock. Find out more about validation tests.
The qualification of electronic boards consists in checking that they meet the specific requirements of their use, such as industrial and safety standards.
Reliability of electronic test benches
The reliability of electronic test benches is essential to ensure accurate and reliable test results. Test benches must be designed with quality components that are resistant to wear and fatigue, and must undergo rigorous reliability tests before being put into service. Electronic test benches must also be regularly maintained and repaired to prevent failures and measurement errors.
Electronic test benches can be used to test different types of electronic boards, including digital boards, radio frequency boards, optical boards and power boards. The test requirements for each type of board may vary according to their use and technical characteristics.
