Investing in a test bench is a strategic decision. It will be responsible for ensuring the quality, reliability, and traceability of your product. However, without good technical planning, the bench can become a bottleneck — or worse, a blind spot in your process.
Before building or acquiring a test bench, make sure to answer these 10 essential questions:
1. What is the purpose of the test?
Is it a functional, in-circuit, electrical safety, RF, visual, or end-of-line (EOL) test? Knowing this defines the type of instrumentation and the complexity of automation.
2. What is the expected production volume?
Will we produce 10 or 10,000 pieces per day? The volume impacts the type of jig (manual, pneumatic, motorized), parallelism, cycle time, and number of stations.
3. What is the available cycle time (Takt Time)?
How many seconds per DUT can you spend? This metric defines the need for automation, parallel testing, and sequencing structure.
4. Does the product need to be tracked?
If so, it will be necessary to integrate code reading systems (QR, datamatrix), database, serial number, and operator control.
5. Are there variants or different models of the DUT?
If the bench is used for multiple versions, it needs a flexible parameterization and automatic identification system.
6. What are the DUT interfaces?
UART, I2C, CAN, RS-485, HDMI, RF, analog or digital inputs… This determines the type of instrumentation, fixturing, and software that will be used.
7. What is the usage environment?
Will it be in a production line with noise and vibration? Or in an R&D laboratory? This affects the level of mechanical robustness and electrical protection required.
8. What software tools will be used?
Do you need integration with TestStand, LabVIEW, Python, MES, Power BI, or ERP? The architecture must allow for future expansions.
9. Will there be manual, visual, or rework tests?
Plan if the bench should contain a graphical interface, guided instructions, or assisted retest mode, with well-defined workflows.
10. What are the expected performance indicators?
Do you want to monitor FPY, CPK, cycle time, failure rate, station availability? The bench must be able to collect and report data in real-time.
