OFHC Copper Backing Plates

Features

Machined from oxygen-free, high-conductivity copper.

For regular, circular disc-type sputtering sources
TORUS^® 2, 3, and 4 accepts a 0.092" thick backing plate, found in the ordering table below
Most sputter sources accept a 0.125" (1/8") thick target bonded to a 0.125" thick backing plate
For targets of other thicknesses, choose the backing plate thickness to adjust the total thickness to 0.250" (1/4") to suit most applications

NOTE:

Those identified in the chart by diameter and thickness only are plain discs without through or tapped holes.
They are suitable for most circular target sources from other manufacturers, although they may need minor machining for screw, clamps, etc.
Copper Cup Backing Plates available upon request.
