Patent ID: 7663891

Claim:
A component mounting board structure, wherein mounting components mounted on a component mounting board are formed by heat generating components having large self-heating characteristics and non-heat generating components having no self-heating characteristic or hardly having self-heating characteristics, the heat generating components are divided into a low heat-resistance heat generating component and a high heat-resistance heat generating component according to heat-resistant limitation temperatures, the non-heat generating components are divided into a low heat-resistance non-heat generating component and a high heat-resistance non-heat generating component according to heat-resistant limitation temperatures, and heat radiation or heat block is performed by interposing resin layers among a low heat-resistance heat generating component mounting region where the low heat-resistance heat generating component is mounted, a high heat-resistance heat generating component mounting region where the high heat-resistance heat generating component is mounted, a low heat-resistance non-heat generating component mounting region where the low heat-resistance non-heat generating component is mounted, and a high heat-resistance non-heat generating component mounting region where the high heat-resistance non-heat generating component is mounted.
