What is Auto Opening?
Auto Opening is a Fixture customisation that is designed to automate the process of opening test fixtures, improving efficiency and reducing manual effort during the testing of units under test (UUT). This system uses two pneumatic cylinders to automatically open the fixture gate, which is controlled by a pneumatic solenoid valve integrated into the UUT’s testing programme.
Benefits of Auto Opening Fixture
An auto opening test fixture streamlines the testing process and reduces operator fatigue by eliminating the need for manual opening after each test. The integration of the solenoid valve control into the testing programme ensures seamless operation, enabling consistent and reliable testing cycles.
In Summary
The Auto Opening Fixture offers an efficient, automated solution for opening test fixtures, reducing manual intervention and enhancing the overall testing process. It is particularly beneficial in environments where quick turnaround and operator efficiency are crucial.
FAQs
What is an auto‑opening test fixture?
An auto opening test fixture is a pneumatically assisted system that opens and closes automatically, reducing operator effort and ensuring consistent, repeatable clamping pressure during PCB testing.
Why use an auto‑opening fixture instead of a manual fixture?
These fixtures improve operator safety, reduce fatigue, and provide more consistent test results. They are ideal for high-volume production environments where speed and repeatability are essential.
How does an auto‑opening fixture work?
The system uses pneumatic cylinders to lift the top plate and apply controlled pressure when closing. This ensures the PCB is pressed evenly onto the test probes without excessive force.
What PCB tests can be performed with an auto‑opening fixture?
These fixtures support ICT (In-Circuit Test), FCT (Functional Test), continuity testing, programming, and combined test strategies depending on your requirements.
Can auto‑opening fixtures reduce operator error?
Yes. Automated operation ensures the correct pressure is applied every time, reducing the risk of misalignment, incomplete probing, or damage caused by manual over-clamping.
Are auto‑opening fixtures suitable for large or complex PCBs?
Absolutely. They are especially beneficial for larger boards or assemblies with high probe counts, where manual clamping would require significant force or introduce uneven pressure.
