|
Melts
and then resolidifies the surface of the Ta metal at a high temperature
in a vacuum.

Forming |
|
Uses
anode oxidation in an oxygen acid solvent to create a thin oxide
film on the surface of the Ta metal to serve as the dielectric.

Cathode
attachment |
|
First
a graphite and then a silver coating is applied to provide a cathode
contact.

Positive
terminal weld |
|
The
tantalum wire is electrically welded to the positive terminal of
the lead frame while in the negative contact the silver is connected
with paste.
