  Conventionally, in the production of electronic circuit boards for various electronic devices, for example, board design data based on electronic circuit board design data is given to board manufacturers. Board manufacturers produce boards based on board design data. At that time, the identification information is written in lot units or individual substrate units for production management or distribution management. Next, the board is supplied to the assembly maker, and component mounting data based on the design data of the electronic circuit board is given to the assembly maker. In order to mount the necessary parts on the board and to manage production, the assembly maker writes information such as board identification information in an appropriate space on the board. It is also possible to perform mounting with high productivity by writing information necessary for mounting in the field and putting it in the mounting line.
