NHK SPRING has an unique design probe pin named Socket pin for Wafer Level Test, Wafer Level Burn-In, and Final Test Socket. |

<NHK SPRING Socket pin barrel-less design has a longer life> |
• |
In general, pogo pin has a barrel to support the plunger but in real application this plunger |
|
and barrel will eventually scrub each other and make it easy to wear. |
• |
NHK SPRING Socket pin does not have any barrel and the pin is nestled inside the socket housing |
|
directly. |
|
|
|
<A better electrical characteristic> |
• |
NHK SPRING Socket pin consists an original coil spring design with two portions. |
• |
The active (compressible) portion of the spring provides the force to contact. |
• |
The plunger is located inside the fixed portion of the spring that allows the electric current |
|
flowing through a solid spring (as a short rod) nicely without any losses. |
• |
The electric current does not flow through the active coil. |
• |
The unique structure contributes greatly to a very low inductance (min of 0.6nH) and a |
|
very minimum insertion loss. |
|
|
|
<Variety of the pin tip geometry, materials and tight pitch capability> |
• |
NHK SPRING has a wide variety of the pin tip geometry, materials and surface finished to |
|
fit the customer requirements. |
• |
NHK SPRING Socket pin is capable for 140um pin pitch application.
