Design and manufacturing of electronic circuit test benches

Electronic test benches: what are they used for?

Electronic circuit test benches are essential tools for ensuring the reliability and quality of electronic products and systems, particularly during the industrialization phase. They are used to test and validate electronic circuit boards, check their functionality, and ensure compliance with standards and specifications. In this article, we will delve into the various facets of electronic circuit test benches.

Designing electronic test benches

Designing an electronic test bench is a crucial step in guaranteeing accurate and reliable test results. A test bench must be tailored to the specific requirements of the product being tested, industrial testing standards, and equipment durability. Key components of an electronic test bench include testers, mobile probes, interfaces, data acquisition tools, and Field-Programmable Gate Arrays (FPGAs). Designing such a system requires expertise in electronic engineering, PCB design, wiring, mechanics, power systems, and more.

Functional testing and electrical measurements

Electronic test benches enable functional testing and electrical measurements to verify the proper operation of circuit boards. Functional tests simulate the normal operation of the circuit board to confirm it meets technical specifications. Electrical measurements assess the electrical properties of the board’s components, such as resistance, capacitance, voltage, current, frequency, and power.

Validation and qualification of electronic circuit boards

The validation and qualification of circuit boards are critical for ensuring their reliability and compliance with standards and specifications. Electronic test benches are used to validate circuit boards by simulating real-world conditions, including temperature fluctuations, pressure changes, electromagnetic interference, and mechanical vibrations or shocks.

Qualification involves verifying that the circuit boards meet specific requirements for their intended use, such as industrial standards and safety regulations.

Reliability of electronic test benches

The reliability of electronic test benches is paramount to ensuring precise and dependable test results. Test benches must be built with high-quality components that resist wear and fatigue. They undergo rigorous reliability testing before deployment and require regular maintenance and repairs to prevent failures and measurement errors.

Electronic test benches can be adapted to test various types of circuit boards, including digital boards, radio-frequency boards, optical boards, and power boards. Testing requirements vary based on the application and technical characteristics of each type of board.
