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 proper technical planning, the test bench can become a bottleneck — or worse, a blind spot in your production process.
Before designing or purchasing a test bench, make sure you can answer these 10 essential questions:
1. What is the purpose of the test?
Is it a functional test, in-circuit test, electrical safety, RF, visual inspection, or end-of-line (EOL)? The answer defines the required instrumentation and the complexity of the automation.
2. What is the expected production volume?
Will you produce 10 or 10,000 units per day? The volume influences the type of jig (manual, pneumatic, motorized), test parallelism, cycle time, and the number of stations required.
3. What is the available cycle time (Takt Time)?
How many seconds per DUT can you afford? This metric defines the level of automation, the need for parallel testing, and the structure of the test sequencing.
4. Does the product need to be traceable?
If so, you’ll need to integrate code reading systems (QR, datamatrix), databases, serial number management, and operator control.
5. Are there variants or multiple DUT models?
If the bench will be used for multiple versions, it must have a flexible parameterization system and automatic model identification.
6. What are the DUT’s interfaces?
UART, I2C, CAN, RS-485, HDMI, RF, analog or digital inputs… This will determine the required instrumentation, fixturing, and test software.
7. What is the test environment?
Will it operate on a production line with noise and vibration, or in an R&D lab? This affects the mechanical robustness and electrical protection level needed.
8. Which software tools will be used?
Do you need integration with TestStand, LabVIEW, Python, MES, Power BI, or ERP? The software architecture should allow for future scalability.
9. Will there be manual, visual, or rework tests?
Plan whether the bench should include a GUI, guided instructions, or an 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, or station availability? The bench must be capable of real-time data collection and reporting.
