Connection structure and manufacturing method thereof, magnetic head tab combination, magnetic head driving crane combination and hard disk driving unit

Abstract

The invention discloses a connecting structure among electronic elements, which comprises electrical contacts and metal balls, wherein the electrical contacts are respectively attached to the electronic elements, and the metal balls are used for connecting or welding the electrical contacts; the connecting surfaces of the electrical contacts face to the same direction so that operation for forming the connecting structure is easier. The two electronic elements are respectively provided with a first base and a second base superposed on the first base. A first and a second electronic contacts are arranged on the second base of the corresponding electronic elements and each is provided with an extending portion extending the edges of the second base and the first base. The metal balls are arranged on the extending portions of the first contact and the second contact. The invention also discloses a method for forming the connecting structure and a magnetic head folded sheet combination, a magnetic head drive arm combination and a magnetic disc drive element with the connecting structure.

Description

technical field [0001] The invention relates to a connection structure and a connection method between electronic components. More particularly, the present invention relates to a connection structure between elements of a magnetic disk drive unit. In particular, the present invention relates to a head gimbal assembly (HGA), a head stack assembly (HSA) and a disk drive unit using the connection structure. Background technique [0002] Electrical connections are widely used to transmit digital signals between components such as printed circuits, electrical conductors, contacts, and other electronic devices. The electrical connection between components is mainly achieved by using some techniques. The technique includes, for example, connecting both ends of the flexible wire through connectors, or forming special connectors such as copper bumps through flexible printed circuits to electrically connect with other external devices. In particular, disk drive units also use elec...

AI Technical Summary

Problems solved by technology

Therefore, the electrical connection performance of the HGA 150 is greatly affected

Also, the soldering requires the application of pressure to ensure a high quality electrical connection, however the pressure may damage the flexure 155 and components around the flexible printed circuit 165

[0009] In addition, the tin connection method in the prior art is carried out on the opposite side of the flexible printed circuit 165 and the flexible member 155

This operation is difficult to control the diffused tin, so it may cause a short circuit, which greatly affects the realization of the function of electrical connection

Overall, existing tin connections add complexity and difficulty to the manufacturing process, resulting in very low production yields and unusually high manufacturing costs
