Abstract
A printed wiring board includes a first outer surface, a second outer surface, and an electronic circuit. The second outer surface is opposite to the first outer surface. The electronic circuit includes at least one specific design circuit block and at least one common design circuit block. The at least one specific design circuit block is provided on the first outer surface and designed in accordance with a specification of a device to which the printed wiring board is applied. The at least one common design circuit block is for a common use regardless of the specification of the device. The at least one common design circuit block is provided on the second outer surface.
Claims11
A printed wiring board which constitutes an electronic circuit formed of at least two circuit blocks, comprising electric parts being mounted on each of two outer layers of the printed wiring board so as to form at least one of the circuit blocks, wherein at least one of the circuit blocks formed on one of the outer layers is a separate design circuit block which is designed separately in accordance with a specification of a device to which the printed wiring board is applied, and at least one of the circuit blocks formed on the other of the outer layers is a common design circuit block which is used in common irrespective of the specification of the device to which the printed wiring board is applied,
- wherein the electronic circuit is a control circuit, and the separate design circuit block is a circuit block including an analog circuit which is configured to process a sensor signal received from an outside and/or to output a drive signal for driving a control object, and
- wherein the common design circuit block is a circuit block including a digital arithmetic processing circuit which is configured to arithmetically process a signal from the at least one separate design circuit block and to output a signal of a result of the arithmetic processing to the at least one separate design circuit block.
A printed wiring board comprising:
- a first outer surface;
- a second outer surface opposite to the first outer surface;
- and an electronic circuit comprising:
- at least one specific design circuit block provided on the first outer surface and designed in accordance with a specification of a device to which the printed wiring board is applied;
- and at least one common design circuit block for a common use regardless of the specification of the device, the at least one common design circuit block being provided on the second outer surface, wherein the at least one specific design circuit block includes a first analog circuit to process a sensor signal received from a sensor disposed outside the printed wiring board;
- and wherein the at least one common design circuit block includes a digital arithmetic processing circuit to arithmetically process a signal output from the at least one specific design circuit block and to output a signal including a result obtained through the arithmetic processing to the at least one specific design circuit block.
