DEVICE MOUNTED WITH CHIP TYPE ELECTRONIC PARTS

PURPOSE:To obtain a device which can surely electrically and mechanically connect and mount a chip type electronic parts on the land of a board, even if a little position deviation exists. CONSTITUTION:A pair of streak type conducting lands 3 are formed on a wiring pattern 2 of a board 1. Said land 3 is constituted by arranging a plurality of line lands (a) in a rectangle at constant pitches. The expanded area of each line land (a) is a little larger than an electrode 6 of the electronic parts 5, and sufficiently covers the position deviation of the electronic parts 5 The width and the interval of the line land (a) is so set that the electrode 6 of the electronic parts 5 is mounted on at least two line lands (a). It is also effective that the conducting lands are dispersed in dot on the same expanded area as the streak type conducting lands 3.
