ENGINEERING ANSWER
A complete test plan separates bare-board connectivity, impedance control and RF functional performance. Each test answers a different question and should be tied to a stated acceptance requirement.
What to decide before release
Define the frequency range, reference planes, fixtures and calibration method for RF measurements. Record the measured construction and environmental conditions. Retain raw S-parameter data where it is useful for model correlation.
Checks to put in your design brief
- Define bare-board electrical tests
- Specify coupon acceptance
- Plan VNA calibration and de-embedding
Important distinction
A continuity test does not prove low insertion loss, and a passing RF sample does not replace production quality controls.
