Engineering FAQ
How should impedance tolerance be specified?
Target, tolerance, line type, reference, coupon type, measurement method.
Which reliability tests for long-life PCBs?
CAF, IST, thermal cycling, SIR. Plan depends on environment.
How does copper roughness affect insertion loss?
Skin effect: rougher copper increases loss. Lower roughness reduces loss but requires adhesion control.
When should backdrilling be used?
Remove via stubs at high data rates. Specify stub limits, backdrill depth tolerance, verification.
What defines a high-speed PCB vs an RF PCB?
High-speed PCBs driven by digital edge rates; RF by analog amplitude/phase stability. Both need controlled impedance, material priorities differ.
