Abstract

PURPOSE:To make the temperature and strength of junctions uniform and to improve their reliability when all the lead terminals are heated and fixed by pressure in a batch joining manner, by making uniform the shape, area, material and structure of all the junction terminals and pattern width of wirings connected thereto. CONSTITUTION:The shape, area and materials of all the junction terminals 2 of a printed board and the width of a wiring pattern 3 connected thereto are made uniform. A junction terminal 2 is connected to a through hole 4 by a narrow and long pattern 3 to reduce heat dissipation. Heat resistance, heat dissipation and temperature of all the junctions are made uniform thus allowing uniform and batch junction.
