Abstract

PROBLEM TO BE SOLVED: To identify a polarity when a part is mounted, by making land configuration of at least one place different from that of other lands on the same part. SOLUTION: A land 1-1 is shaped to a pentagon to be differentiated from a rectangle of other lands 1-2. Thereby, when an electronic part 1-3 with a polarity is mounted on lands 1-1, 1-2, it is possible to tell whether it should be mounted on a position such as a first terminal 1-5, etc. Furthermore, even after mounted, it is possible to tell whether or not it is mounted with a right polarity from the land 1-1 and a polarity mark 1-4 of an electronic part. Therefore, an appearance inspection after mounting can be carried out only by a land configuration of a printed wiring board. Therefore, it is possible to disuse a symbol on a printed wiring board, to reduce a cost and to improve mounting efficiency.

In the above prior art, no consideration is given to discriminating the polarity and type of the component in the land shape, and the polarity of the component is required for component mounting work and appearance inspection after mounting. , It is necessary to print a symbol mark on the printed wiring board for identifying the type. For this reason, it is necessary to secure a space for printing the symbol mark, and the component mounting efficiency is reduced. In some cases, it is necessary to increase the board size in order to secure a printing space for the symbol mark. Printing the symbol mark also had an effect on the cost of the printed wiring board.
