Inventor: KADOTA KENJI
IPC: H05K1/05
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To prevent generation of a crack in solder and its surrounding even when a severe change in temperature is applied by setting the product of Young' s modulus and thermal expansion coefficient of an insulating layer at a specified temperature to a specified value or less. SOLUTION: For at least one unit layer out of unit insulating layers existing more than one, the product of Young's modulus (Pa) and thermal expansion coefficient (1/K) at 300 K is 2×102 Pa/K or more and 2×106 Pa/K or less, and preferably, 2×103 Pa/K or more and 2×105 Pa/K or less. If the product of Young's modulus and thermal expansion coefficient at 300 K exceeds 2×106 Pa/K, the effect of stress relaxation is not exhibited adequately, while a layer having the product of Young's modulus and thermal expansion coefficient at 300 K of below 2×102 Pa/K is difficult to manufacture. It is more effective to lower the product of Young's modulus and thermal expansion coefficient in a unit insulating layer that is attached to the metal plate out of the unit insulating layers.
