Fine Clad Materials by Toyo Kohan

 

Fine clad materials by Toyo Kohan - a Marubeni Sunnyvale trading partner - is manufactured via a surface activated bonding process within a vacuum environment, which enables the bonding of a variety of materials. Characteristics such as its high level of purity, and dead flat interface make them excellent for use in electronic components, semiconductor packages, Printed Circuit Boards (PCB), safety vent for Li-Ion secondary battery, CPU heat sink (as well as IC heat sink) , and also other electrical applications.

Laminated metal sheet in thickness between 20 and 400 microns can be formed with various metal combinations among Al, Cu, Ni, Ag, Pb, SUS, and Sn, etc.
Fine clad materials are etchable, and can be engraved and welded.
