Title: Method of mounting electronic component
Inventor: SAIDA MITSUGI
IPC: H05K1/11
Filed: 1987-08-12
Abstract: PURPOSE:To improve the operability at the time of mounting surface mounting electronic components of multiterminals by a soldering iron method, by increasing the length of an electrode pattern only at an arbitrary one of terminals of the opposite faces of the component in the shape of the pattern for connecting lead terminals. CONSTITUTION:When surface mounting electronic components of multiterminals are placed by a soldering iron method on a printed circuit substrate 3, one terminal of the face opposite to position the component is first soldered to electrode patterns 4, 5. In this case, the larger the pattern for soldering the component by retaining the component is, the better the operability is. However, if it is excessively large, the peripheral area of the component is increased and it cannot be decreased in size. Then, only the minimum required pattern for positioning is increased, but the other is formed in a necessary minimum area, and they are associated to form an efficient electrode pattern. Thus, since only the pattern for positioning a surface mounting IC may be increased and provided, the efficiency of mounting operation of the IC can be improved, and a size reduction can be simultaneously performed.
