CL-NC Alkaline Copper for
Direct Plating on Aluminum

CL-NC Alkaline Copper is a cyanide-free,
semi-bright copper electroplating process that’s
compatible with aluminum, and most base metals.

If your goal is to eliminate cyanide in the wastewater . . . if you’re looking for
an aluminum plating system that doesn’t require zincate make-up and maintenance . . .
CL-NC Alkaline Copper from Uyemura is the technology you’ve been looking for.

CL-NC Copper can be plated directly on aluminum and most aluminum alloys
that contain less than 1% silicon, without the need for zincate processing.
Aluminum 6061, 5052, 2024 and 1008 are examples of popular alloys that are
successfully plated. CL-NC Alkaline Copper replaces the cyanide copper strike used
prior to zinc die cast plating. Its relatively small grain size means deposits are
more dense; they are also more corrosion resistant, and more resistant to
thermal shock than conventional plating processes.

CL-NC Alkaline Copper has a neutral (7-8.5) pH, and plates at 140-158°F.
It offers exceptional adhesion properties, and is ideal as a base for bright nickel /
microcrack / chrome finishing, and, when used with a nickel barrier, as a base for
plating gold. Applications such as the wheel shown here, plumbing products, appliances,
bicycle hubs and apparel fasteners all benefit from CL-NC processing.

CL-NC Alkaline Copper was developed by CL Technologies-Germany and
has four bath components:

CL-NC Metal Salt
CL-NC Conductivity Salt
CL-NC Stabilizer Solution
CL-NC Brightener

CL-NC Copper is exceptionally versatile:

Making up the copper and conductivity salts at the low end of the
recommended concentration range improves throwing power and
deposit uniformity.
Making up the copper at the high end of the concentration range
enhances overall productivity.
Low pH values will produce very right deposits.
Higher pH values produce a darker deposit.
The product is compatible with both rack and barrel applications.

CL-NC simplifies your operation in several ways. Environmentally, the product
is ammonia-free and does not contain chelates, so waste treatment is easier and
less costly. It does away with the need for cyanide destruct equipment. And CL-NC
Copper’s non-cyanide formula can minimize both fire and liability insurance costs.

New Technologies from MEC Company LTD
Deliver Maximum Adhesion, Less Waste,
Low Energy Processing

Our H2SO4-H2O2-type microetching agent is an exceptional alternative to
black oxide treatment. The unique surface topography produced enhances the
adhesion of copper to all resins including high Tg and HF (halogen-free).

MEC COPPERSEAL Organic Solderability Preservative enhances solderability
by forming an anti-tarnish film that provides exceptional resistance to moisture
and heat.

MEC ETCHBOND is a single-component copper treatment for use prior to
resist or soldermask. Its unique surface topography provides the very best
adhesion on resin systems.

IPC 2010 proved an exceptional opportunity for Uyemura management and technical
specialists to meet with customers and prospective customers who had contacted us regarding
CL-NC Alkaline Copper and other new technologies. Among those representing Uyemura,

George Milad, Laura Hanna and Don Gudeczauskas. Attendance figures for the 4-day event,
released April 20, indicated a 10% increase over last year, with 3,702 attendees. In all,
6,683 attendees and exhibitors representing 41 countries participated in IPC APEX EXPO,
the largest event in North America dedicated to the electronic interconnection industry.

Uyemura Boosts West Coast Resources

Uyemura USA has greatly expanded its representation in the
Pacific Northwest with the news that Chemithon Surface Finishing, Inc.
will represent the complete Uyemura product line in Washington,
Oregon, Idaho, Montana and British Columbia.

Chemithon Surface Finishing was formed in 1972 and quickly became the
largest regional distributor of surface finishing products in the Pacific Northwest.
According to President Jerry Toussaint, Chemithon interests in Uyemura included
its new CL-NC Copper for plating directly over zinc and aluminum die casts,
and its Nickstar decorative black nickel process.

“We think CL-NC represents a huge step forward for companies who are
environmentally aware, and want an alternative to cyanide copper processing,”
he explains. In regard to black nickel, he adds, “we have seen customers who
use other black nickel processes have iridescence and other issues. Uyemura’s
Nickstar is a better chemistry, is extremely consistent, and it has a wider
current density range.”

In addition to Uyemura’s broad line of plating chemistries, Chemithon provides
equipment and services ranging from supplies for simple chemical additions,
to monitoring systems, to comprehensive design, fabrication and installation
of computerized plating facilities.

Uyemura USA is pleased to announce that Paramount USA,
a prominent supplier of primarily laminate and prepreg products,
will represent Uyemura PCB product lines in southern California.
The announcement was made by Uyemura Director of Operations,
Don Walsh.

According to Paramount Sales Manager, Mike Muck, “we think this is a very
strategic ‘fit’ that will serve our existing customers well, and create new
opportunities for companies who want a fully integrated solution.”

Although representing the entire Uyemura PCB product line, Paramount will,
according to Walsh, focus primarily on ENIG, immersion silver and other
final finishes, EPL acid copper, EVF via fill coppers, electroless golds and
palladiums. Paramount will also represent micro-etchants manufactured
by MEC, and Umicore-Galvanotechnik gold processes, two product lines
available in North America exclusively through Uyemura.

Paramount USA and Uyemura are both members of IPC, a global association
serving the electronic interconnection industry. Southern California has
North America’s largest concentration of PCB manufacturers. The world
market for PCBs is projected to top $76 billion by 2015.

Director of Operations Don Walsh and National Accounts Manager
George Milad were featured in a short video produced at IPC that
discusses, among other things, IPC’s new ENEPIG specification.
