Electroless Gold and
Electroless Nickel for
Ceramic Substrates
|
AuBEL Electroless Gold
– Stable,
alkaline pH, autocatalytic process.
Proven
over time, this system has been used
in
production for over 12 years. Properties
of
the system:
|
|
| |
|
High deposition
rate of 80 microinches per hour |
| |
|
Pure gold deposit,
greater than 99.9% |
| |
|
Excellent gold wire
bond properties |
| |
|
Gold and reducer can
be replenished |
|
BEL-801
Electroless Nickel
– Boron electroless nickel for
deposition over metallized ceramic substrates.
System operates
at a neutral pH. Features include:
|
|
| |
|
Excellent
solderability |
| |
|
Nickel purity over
99% |
| |
|
High as-plated hardness
of approximately 800 Hv |
| |
|
High conductivity
electroless nickel deposit |
| |
|
Fast initiation onto
catalyzed surfaces, thus eliminating skip
plating |
| |
|
Long bath life of
up to 5 metal turn overs |
|
Pre-Treatment
for Electroless Plating of Metallized
Ceramics –
Uyemura has
a variety of pre-treatment processes
available for the
cleaning and activation of metallized
ceramics. Specific systems are
available for standard ceramics, low
temperature co-fired ceramics,
glass ceramics, and aluminum nitride.
The net result is a uniform
catalyzation of the metallized surface
without damage to the
underlying ceramic substrate. |
|
Thru-Nic
CL – Super
high throwing power electrolytic nickel.
One disadvantage of sulfamate or sulfate-based
electrolytic nickels
is the lack of throwing power, or the
inability to deposit nickel in
multiple locations without elaborate
anode-cathode arrangements.
These problems
are eliminated with Thru-Nic. Thru-Nic
typically
yields a 5-fold increase in throwing
power over standard nickel
systems. The net result is an improvement
in both quality
and productivity.
