Abstract
The electronic circuit unit of the present invention is provided with the broad width lands and the thin width lands tied with the broad width lands, which are configured by a solder resist that is formed on the surface of the circuit board. Owing to this configuration, the solders placed on the thin width lands are drawn toward the broad width lands, which increases the quantity of the solder buildup on the broad width lands, and accompanied with this increase, swells the heights of the solder buildup on the broad width lands. Thus, the electronic circuit unit of the present invention ensures the soldering.
