Multi-row lead frame, multi-row LED lead frame, manufacturing method thereof, and LED package manufacturing method

摘要

PROBLEM TO BE SOLVED: To reduce the electrodeposition amount of the noble metal forming the outermost plating layer as much as possible to reduce the cost as much as possible, to prevent the burr of the reflector resin from occurring, and to provide the reflection function of the pad portion and the lead portion on the LED element mounting side. Providing a multi-row lead frame that can be held well. A multi-row lead frame including a first strip-shaped region 1-A and a second strip-shaped region 1-B, wherein an outermost layer formed by electrolytic processing is formed on the entire surface of a lead frame base material 10. It has laminated plating layers A1, A2, A3, A4 made of noble metal plating layers, and the laminated plating layers A1, A2 have different thicknesses of the outermost plating layer between the first strip-shaped region and the second strip-shaped region, In the laminated plating layers A3 and A4, the thickness of the outermost plating layer is different between the first strip-shaped region and the second strip-shaped region, and the stacked layers formed in the second strip-shaped region on the front surface side and the back surface side, respectively. The thicknesses of the plating layers A2 and A4 are thinner than the thicknesses of the laminated plating layers A1 and A3 formed in the first strip-shaped region. [Selection diagram] Figure 1
