Abstract:
1. A method of manufacturing a head suspension, the head suspension including a base, a load beam connected to the base, a first wiring member having a first metal base, a first insulating layer, and a first conductor layer that are sequentially layered one on another, and a second wiring member having a second metal base, a second insulating layer, and a second conductor layer that are sequentially layered one on another, the first wiring member having a first bonding part, the second wiring member having a second bonding part, the first and second bonding parts being bonded together by reflowing solder arranged on at least one of the first and second bonding parts, the manufacturing method comprising steps of: positioning the first and second wiring members so that the first and second bonding parts face each other with the solder interposed between them; and heating and pressing the metal base behind one of the first and second bonding parts with a pressing face of a heater chip being coated with a nickel film so that the first and second bonding parts lie one on another and the solder is heated and reflows to bond the first and second wiring members together and; wherein the first and second metal bases are made of stainless steel, and the hardness of the nickel film is substantially equal to that of the stainless steel.
