Abstract
The present bonded structure uses metal ball to bond or weld the respective bonding surfaces of electrical pads which are arranged to face the same direction. The structure can be controlled visually and thus enables a high connection quality of no short circuit. In addition, the bonding operation of the bonded structure is carried out without using pressure, thus it will not damage surroundings of the electrical components. Accordingly, the manufacture yield is significantly improved and the cost is prominently reduced. The present invention also discloses a bonding method and a head gimbal assembly and a head stack assembly and a drive unit using the bonded structure.
