<p>PURPOSE:To prevent a chip rise by setting the distance between the central points of lands facing each other to the one not exceeding the length of each chip component. CONSTITUTION:Circular lands are so formed as to face each other on the surface of a glass epoxy substrate 1. Then, two chip components 3, 1.0 by 0.5mm chip capacitor C and chip resistance R, are joined respectively to the lands 2. Since the lands 2 are circular, there is no chip rise occuring even in the case that the distance P between the central points 2a, 2a of the lands facing each other is larger than the length l of each of the chip components 3. The outer part of each of the lands is best in the shape of an arc of a fixed radius of curvature. Compared with the conventional types, however, circular lands whose radius of curvature is not fixed or polygonal lands which have corners of obtuse angle can be also good for preventing a chip rise.</p> |
