Abstract:
A design evaluating method for assisting circuit-board-assembly for a design and assembly operation which includes designing a circuit for a desired function, designing a pattern on a circuit board to form the circuit, and then performing engineering-trial manufacture of a component-mounted-circuit board by mounting components on the circuit board, the method comprising:performing a first design evaluation or a second design evaluation with considerations given to both sides of design and assembly processes, the design process side where the circuit design and the pattern design are involved and the assembly process side where electronic components are mounted onto the circuit board before the engineering-trial manufacture of the component-mounted-circuit, wherein the first design evaluation with respect to the circuit design and electronic components selection evaluates differences between an actually performed circuit design and a target circuit design, and differences between components selection and target components selection, wherein, in the first design evaluation, the target circuit design and the target components selection being targeted for quality improvement in an assembly operation in the assembly process of mounting the electronic components onto the circuit board, and wherein the second design evaluation with respect to design of the circuit board and the pattern design of the circuit board, evaluates differences between an actually performed circuit board design and a target board design, and differences between a pattern design and a target pattern design, and wherein, in the second design evaluation, the target board design and the target pattern design are targeted for the quality improvement in the assembly operation.
