Uyemura – our central research
labs in Hirakata (a suburb of Osaka,
Japan) have over 70 full time R&D
professionals dedicated exclusively
to the development and optimization
of functional and decorative plating
chemistries.

Our Taiwan company has nearly a dozen additional R&D
professionals assigned to new product development.

Uyemura also has R&D centers in China and Malaysia; the latter has
been responsible for groundbreaking work in general metal finishing.

Some of the industry's most important recent developments in nickel
technology have been Nickstar decorative black nickel, ANP Electroless
Nickel Plating for Aluminum
, and ANP1012. The latter is a lead-free RoHS
product that enables plating of nickel phos alloys in the range of 10-12
weight percent phosphorus. All 3 of these were developed by the
Uyemura USA facility in Southington, CT, which is proudly
commemorating its 13th year of service to industry.

What Are Our Newest Developments?

Uyemura GRX-70 high-speed electrolytic process:
the 22,000-hour solution to tin whisker formation.

Uyemura ANP Electroless Nickel Plating for Aluminum
an important new technology that uses Uyemura’s lead and
cadmium-free electroless nickel product with proprietary
cleaning, etching and zincating technologies to deliver
excellent adhesion through six or more MTOs.

   
Presa RMK-30 Immersion Tin for PWB and PKG – a fluoride-free
immersion tin that provides excellent solderability – even with
high-temp, lead-free solders.

   
MEC Company LTD an Osaka company providing Uyemura customers
access to 35 more R&D professionals specializing in products for
