Micro
Tube has features of “uniform Au plating inside”, “spotless
|
surface
smoothness”and
“highly precise cylindricalness
and
|
coaxialness”,which
are
produced
by
our
original processing
and

How
to produce Micro Tube by electroforming
|
Nickel
plating (electrodeposition) is taken on electric
wire which
|
is
used for both a mold and
electrode.
|
The
wire is removed
after that, and
pipe-shaped Micro
Tube is finally
procured.
|
The
diameter
of the
wire is
conformed
to the
inner
diameter
of
|
Micro
Tube,
as
well
as
the
surface
smoothness.
by
the
same
token.

Crystalline
Dimension and Mechanical Properties
of Electroformed Ni super-micro
tubes |
|
|
Abstract: |
Crystalline
dimension and Young’s Modulus
of Electroforming Ni super-micro
tubes were |
| investigated.
In
X-ray
spectroscopic
analysis,
broader
diffraction
peak
spectra
were
observed |
and
it indicated a small size multi-crystalline
structure. In SEM and TEM analyses,
15 〜 55 nm |
size
multi-crystalline structures
were observed. By mechanical
measurements, the average |
Young’s
modulus
was
167
GPa
and
this
value
is
about
80
% of
ordinary
Ni
material.
This
means |
that
Electroforming
Ni
super-micro
tubes
have
suitable
elastic
properties
as
for
contact
probe |
materials. |
