Precious metal terminations are screen
printed onto a ceramic base and fired.
The resistive element is screen printed
and fired and the passivation layer
added. Each resistor is trimmed to
tolerance by sand blasting. The
prescribed tile is broken into strips, the
end plating is fired on and the strips
broken into individual components.
Final
termination
is
made
by
electroplating.
