Silvered Mica Plates
All cut mica plates are electrically tested by means of a high frequency spark for conducting particles and pinholes. They are then metallised with a silver paste by a screen printing method to form a thin electrodes-less than 3 mm. Silver paste is printed onto the mica in different patterns as per required specification. The actual silver metallisation is done within a range of 5 to 8 microns on both sides.The deposited layer of silver is controlled to achieve its required capacitance. Glass is used as the fusing agent. The metallising bond which unites these two elements permits diffusion of heat over a wider surface. While the points of calorofic transfer are increased, the thermic resistance does not influence the insulation of the unmetallised area of the film.
