A plurality of bonding structures and their forming methods for bonding a FPC to a bonding pad, in particular a bonding pad of a wireless suspension in a head gimbal assembly, using anisotropic conductive adhesive; such structures eliminate the spring-back force in typical anisotropic bonding to ensure durable bonding. At the same time, these structures also allow for reworkability under which the bonded parts can be separated easily.

摘要:
A magnetic head with an air bearing surface to which an appropriate roughness, a method of manufacturing the same, and a magnetic disk apparatus are provided. A head core part is formed on a base body made of altic formed by dispersing grain titanium carbide into alumina, and then an air bearing surface is formed. Next, plasma oxidation is performed so that a number of protrusions with height of about 5 nm are selectively formed only on the base-body region of the air bearing surface. The protrusions are composed of titanium oxide formed by the exposed portion among titanium carbide grains on the air bearing surface being selectively oxidized. Growth of the protrusions is promoted by applying photoresist on the ABS and removing it before performing plasma oxidation. The magnetic head has no risk of adsorbing a recording medium so that it has excellent CSS.

A surface treatment method for solder joint employs alkali buffer solution dipping the solder joint and the alkali buffer solution reacts with the solder joint thus yielding a passive layer. As the resultant passive layer forms on the surface of the solder joint, thereby prevents further corrosion and dissolution during aqueous cleaning or water dipping thereafter. In addition, the passive layer ensures a good appearance with maximum protection of the solder joint and also provides a sound reliability and a high testability of a finished electronic product equipped with the solder joint.
摘要:
A connecting portion of the external side FPC board connected to a control circuit provided outside of a magnetic head assembly and connecting terminals of arm side FPC boards respectively connected to magnetic heads are overlapped with an anisotropic conductive tape having anisotropic conductivity in the direction of thickness in between. The anisotropic conductive tape is applied pressure between the connecting portion and the connecting terminals with heating to a temperature of, for example, 150° C. and is set. As a result, the connecting portion and the connecting terminals are connected. The anisotropic conductive tape has anisotropic conductivity only in the direction of thickness so that conduction of wirings adjacent each other is prevented although a plurality of wirings is formed on the connecting portion and the connecting terminals.
