Uyemura:
World Leader
in PCB Finishes!




“Powered by science, focused on customers.” 
Uyemura provides exceptional, problem-solving
finishing technology solutions, including the broadest
range of PCB finishes, ENIG, ENEPIG, ENEG, ENAG,
and much more.  Under bump metallization
processes used in semiconductor manufacturing
produce exceptional results on aluminum, copper.
and silicon / SOI wafers.
 
Our mission is to give customers a defined and significant advantage in performance,
cost, and simplified maintenance, and to support each customer with technical support that
is the most responsive, and knowledgeable, in the industry.

   
Uyemura USA is best known for the development of PCB finishes.  We are the
world leader in electroless nickel/ immersion gold systems (“KAT”), also electroless golds,
including AuBel (alkaline pH) and TMX (neutral pH) for gold wire bonding. Equally significant
are Uyemura immersion silver (RGA) and immersion tins, including RMK-30, the most
effective immersion tin available for mitigating tin whiskers.
   
Revolutionary copper chemistries supplied by Uyemura have gained wide acceptance
for their superior performance, and ability to reduce costs related to environmental
compliance and bath maintenance.  Market-leading copper treatments from MEC Company
LTD that are supplied by Uyemura, include microetching agent and a low-energy,
environmentally favored OSP.
   
Markets, as diverse as apparel, food service, and medical device manufacturing,
use Uyemura technologies to distinguish their products, gain market share – or reduce
product liability. The success of Uyemura satin nickels in the automotive sector is legendary,
and has paved the way for other Uyemura technologies, including Nickstar decorative
black nickel, and ANP electroless nickel plating for aluminum.
   
At Uyemura, our lifework is the development, and continuous improvement,
of chemistries and equipment that enhance the performance, productivity and
profitability of the companies we serve.
  We think it says much about our philosophy
that we have twice as many technical support professionals . . . as sales staff. Uyemura
customers are among the most demanding in the world, and there are substantive
reasons why so many Uyemura customers have been customers for years,
and often decades.
   

Whether your interest is high-performing PCB finishes, decorative black, gold or
diamond reflective finishes, or a direct plating system for aluminum
that will let
you say farewell to cyanide destruct systems forever, Uyemura is eager to provide
technologies and alternatives to meet your needs.
