Rivet contacts are produced mainly by
staking spring materials with holes.
Their advantages are,
 |
high speed automatic staking is relatively easy |
 |
a manufacturing cost of single staking is lower than other methods and the costs will be reduced further by integrated production |
 |
adhesive strength of staking contacts used at a small current region is strong and stable enough |
 |
The materials will not lose their spring properties nor be oxidized |

Rivet Contacts
|
| -
|
solid contacts, |
| -
|
clad contacts (where only the top is laminated
by contact materials) |
| -
|
triple-layer laminated clad contacts (where both
the head and leg area laminated by contact materials using Cu
at the center).
|
| Production methods of
clad contacts are cold pressure welding and brazing. |
| F contacts |
R contacts |
Oval contacts |
Conical contacts |
