Other custom electrode configurations are available on request.

Dimensional Range

Diameter from 3mm (0.12”) to 254mm (10”)
Thickness from 0.08mm (0.003”) to 25.4mm (1”)

Custom sizes dimensions outside of the above may be possible – please consult for further information.

Standard Mechanical Tolerances

Diameter ± 0.150mm
Thickness ± 0.05mm

Tighter mechanical tolerances are achievable but are dependent on the disc diameter and thickness.

Metallisation Type

Standard metallisation: Silver fired thick film
Evaporated nickel
Electroless nickel - Gold flash
Gold over Nichrome - Evaporating (others available on request)
