Electronic passive component having marking area for tracing production history
An electronic component includes a member with marking having at least one marking area to be processed digitally, as well as a member other than the member with marking. The marking allows for tracing the production history of individual electronic components.
1. An electronic component comprised of:
a first member having multiple faces, one of which has first exposed marking configured directly thereon wherein the first exposed marking is digitally processable and first information extracted from an exterior of the first member; and
a second member having multiple faces, one of which has second exposed marking configured directly thereon wherein the second exposed marking is digitally processable and contains second information extracted from an exterior of the second member,
wherein the first information and the second information define a variable whose value falls within a predetermined range so as to desirably assemble the first member and the second member.
2. An electronic component according to claim 1 , wherein the electronic component contains two or more members with marking.
3. An electronic component according to claim 2 , wherein marking areas of the two or more members with marking are each provided on surfaces facing a same direction.
4. An electronic component according to claim 2 , wherein marking areas of the two or more members with marking are each provided on surfaces facing different directions.
5. An electronic component according to claim 2 , wherein marking areas of the two or more members with marking each have different sizes.
6. An electronic component according to claim 2 , wherein marking areas of the two or more members with marking each provide a marking conforming to different standards.
7. An electronic component according to claim 1 , wherein at least one of the marking areas is positioned away from a center of a surface of the member on which the marking area is provided.
8. An electronic component according to claim 1 , wherein at least one of the marking areas has information equivalent to 16 characters or more.
9. An electronic component according to claim 1 , wherein the marking area is marked with a two-dimensional code.
10. An electronic component according to claim 1 , wherein at least one of the marking areas is laser-engraved.
11. An electronic component according to claim 1 , wherein the marking area contains at least one type of record being member data of the member with marking, assembly data of the member with marking, or processing conditions of the member with marking.
12. An electronic component according to claim 1 , wherein the electronic component is a coil component and at least one of the marking areas is provided on a magnetic body.
13. An electronic component according to claim 12 , wherein the electronic component is a coil component and the magnetic body on which the marking area is provided is a drum core.
14. An electronic component according to claim 13 , wherein the electronic component is a coil component and contains two or more members with marking, and the two or more members with marking are selected from a drum core, a coil, a sleeve core, and a resin that contains magnetic grains.
15. An electronic component according to claim 12 , wherein the electronic component is a coil component and the magnetic body on which the marking area is provided is an E-type core, I-type core, and/or pot-type core.
16. An electronic component according to claim 15 , wherein the electronic component is a coil component and contains two or more members with marking area, and the two or more members with marking are selected from an E-type core, an I-type core, a pot-type core, a coil, a combined core, and a resin that contains magnetic grains.
