About
Azuma Denka Industry Co., Ltd. was established in 1982 in Akita Prefecture in northern Japan, and has constantly specialized in plating. In the early days, we mainly handled Ag plating of semiconductor lead frames and Sn-Pb plating, but now our specialties have expanded to include Ni-Au plating of printed circuit boards and Ni-Pd-Au plating of ceramic PCBs.
We are also focusing on technological development. We provide samples made in a beaker or by a laboratory machine depending on the customer’s needs. We evaluate the quality of samples by using a thermal field-emission scanning electron microscope and various other analysis instruments. While honing our existing skills, we are always pursuing new ways of solving plating problems. Under the slogan “Times are changing! The next challenge! – Action,
Cooperation and Challenge,” we strive to satisfy customers’ needs and maintain trust.

Uniform metal circuit patterns
-
High-precision screen printing using an image recognition system makes it possible to form accurate and uniform metal circuit patterns.
-
High-adhesion plating on a metal circuit pattern
-
By using a conductive Cu paste, surface finishes including high-adhesion electroless Ni-Au plating can be applied directly.
