CONTACT PIN  
Probe Pin
     -  Double-Ended
     -  Single Ended
     -  Kelvin Contact
Contact Finger [Single and kelvin contact]
K pin – Tungsten (patent pending)
Spiral Spring / KQ pin / KB Pin
 
FEATURES
Miniature double ended spring loaded contact pin
     -  Minimize coplanarity of the balls on DUT
Pitch: 0.3mm to 1.27 mm
Short contact / short pin length
     -  Minimize capacitance, inductance and contact resistance
     -  Good electrical performance
     -  Best for high frequency / high speed testing i.e. RF-Devices
Special Barrel Design : ensure consistent contact
Long life span : - > 500k in general, up to 1,000k insertions
Solder migration – minimal -> low Maintenance
Wide range of pin sizes
Wide range of plunger tip plating
