Uyemura is the world leader in electroless nickel/ immersion gold, immersion silver, and immersion tin; also copper etchants and acid copper finishes, plus decorative black nickel.


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.


Uyemura specializes in electroless nickel / immersion gold, decorative
black nickel, HASL alternative products, immersion silver, lead and
cad-free finishes, electroless nickel, diamond reflective finishes, and
alternatives to black oxide.

Other industry-leading UIC finishes are acid copper DC electroplate,
ENIG, ENAG, gold wire bonding, electrolytic nickel gold, immersion silver,
immersion tin, and under bump metallization processes for aluminum and
aluminum alloys, and copper.
