Power Supply

Power supply assemblies are used across a wide spectrum of devices and equipment in virtually all electronic markets. Modern power supplies are manufactured all over the world and, as a result, there are a wide variety of board materials, components and process conditions used.

Key Requirements for Joining Materials

High performance under wide process conditions
Excellent value, lowers total cost of ownership
High mechanical and electrochemical reliability
