Filed: 2000-01-27
Abstract: PROBLEM TO BE SOLVED: To provide an electronic component package provided with constitution in which reliability of solder bonding is high when lead-free solder is used. SOLUTION: In a flat IC package 40, a tip end portion 44 of a lead 42 is arranged on a wring pattern of a printed wiring board (which is not shown in Fig.) and made flat so as to be solder-bonded to the wring pattern. A solder- bonding surface 44a of the tip end portion is made rough, and the size of irregularity of the surface is at least 0.5 μm and at most 2 μm. In the flat type IC package, an anchor effect is generated since the solder-bonding surface of the lead is made rough.
