MANUFACTURE OF ELECTRONIC COMPONENT

摘要

PURPOSE:To form a required space on an element simply and to decrease the whole size of an electronic component by applying a silicone rubber for absorbing vibration to an end face of the element, covering the whole by a thermal contraction tube and contracting the tube by heating. CONSTITUTION:In pasting a surface elastic wave filter chip 7 to an insulating board 6 and applying electrical connection thereto, the height of the silicone rubber 8 at both ends of a surface elastic wave propagating line is formed higher than the height of the chip 7. Then, the whole is covered with the thermal contraction tube 9 and the tube is contracted by heating, then a space slightly higher than the height of a silicone rubber 8 is formed on the surface elastic wave filter chip 7. The required space is formed on the surface elastic wave filter chip without using a cap by molding it by a resin 9.
