Abstract

PURPOSE:To improve the adhesion of paste even on a small board whose surface is rough by making a corona discharge treatment to the board as a treatment before applying the paste and baking. CONSTITUTION:First, a corona discharge treatment is made to alumina boards whose surface roughnesses are 0.2mum and 1.0mum using a corona discharge treatment device. The corona discharge device is installed so that a substrate electrode 2 grounded on an insulating resin base 1 is formed and a discharge electrode 3 connected to a high voltage transformer located immediately above the base 1 and supported by a holder 5, can scan in the direction of arrow A. For instance, the corona discharge device is made to scan an alumina board 10 juxtaposed on the base 1 at an output voltage of 20kV and an output power of 130-140W with the discharge electrode 3 moving at a speed of 40cm/sec or 1cm/sec. The distance between the discharge electrode 3 and the alumina board 10 is 1-5mm. The alumina board 10, upon completion of this corona discharge treatment, is screen-printed using a carbon resistance paste and then heated for baking.
