# UNBProbe

### Spring-Loaded Needle Probe

UNBProbe is a passive, spring-loaded needle probe designed for PCB diagnostics.  
The detachable spring-loaded needle permits interchangeability of probe tips.  
The PCB incorporates two solder jumpers and pads for two 0402 surface-mount components positioned adjacent to the probe tip.  
A header facilitates connection of jumper wires and an SMA connector provides interfacing with peripherals.  

### v0.2 Features

- **Optimized via fence**: Redesigned via placement and geometry enhance signal integrity by mitigating crosstalk and reducing parasitic inductance.
- **Curved trace routing**: Smooth, arced trace paths diminish abrupt impedance transitions, resulting in lower reflection coefficients and more predictable high frequency behavior.
- **Manufacturer-compliant SMA footprint**: The SMA connector pad layout adheres precisely to the vendor's mechanical and electrical specifications, ensuring reliable mating and consistent performance.
