Probe Card
The multilayer PCB at the heart of a wafer probe card -- it routes signals between the tester and the probe head that contacts each die on the wafer.

Overview
The multilayer PCB at the heart of a wafer probe card -- it routes signals between the tester and the probe head that contacts each die on the wafer.
Why it matters
A probe card concentrates a very large number of signals into the small area around the probe head. That takes high layer counts, fine line and space, and low-loss materials, with flatness and plating quality held tightly across the board.
Typical Applications
- Wafer sort and wafer-level test
- Semiconductor device characterization
- High-speed and RF device test
- Memory and logic wafer test
Manufacturing Considerations
- Dense signal fan-out around the probe head drives layer count and line / space
- Low-loss laminates such as Megtron keep high-speed test signals clean
- Flatness and gold contact areas matter where the board meets the probe head and the tester
