摘要:
There are provided a solder ball deforming step of mechanically deforming a ball to break an oxide film of a surface thereof and to expose a nonoxide surface and a solder melting step of heating and melting the deformed solder ball through energy irradiation in a state where the deformed solder ball is mounted on joint units of a loaded work. The solder ball deforming step mechanically deforms the solder ball to form at least two orthogonal contact surfaces in contact with the joint surfaces of the joint units.

A method of bonding a piezoelectric element and an electrode, including the steps of forming a first coating of a material selected from the group consisting of Au, Al, Zn, Cu, and Sn on a bonding surface of the piezoelectric element, and forming a second coating of a material selected from the group consisting of Au, Al, Zn, Cu, and Sn on a bonding surface of the electrode. The combination of the materials of the first and second coatings is preferably Au/Au, Au/Al, Zn/Cu, or Sn/Cu. The method further includes the step of bringing the first and second coatings into close contact with each other and heating them under pressure to form a metallic bond or intermetallic compound between the first and second coatings, thereby bonding the piezoelectric element and the electrode.

The present invention relates to a ball capturing apparatus and method of capturing one ball from plural balls having the same size, and to a solder ball disposing apparatus and method of disposing a solder ball containing solder in a predetermined position on a circuit board, thereby reliably capturing one ball from the plural balls having the same size. The apparatus includes: a holding member 111 including a holding wall 111a air-tightly closing a space S that holds a plurality of balls B having the same size and in which a hole 1111 larger than a size of one ball and smaller than a size of two balls is formed in an upper part of the holding wall; blowup means 112 for blowing the balls B held in the holding member 111 upward; and capturing means 12 for capturing a ball B blown up by the blowup means 112 and reached the hole.

A method of assembling a micro-actuator is provided in which a base frame having a plurality of actuator bases is placed on a stage, a first adhesive is applied to each of the actuator bases, and a base electrode frame having a plurality of base electrodes is placed on the first adhesive. The first adhesive is semi-cured by heating and pressing. A second adhesive is applied to each of the base electrodes, and a plurality of piezoelectric elements are placed on the second adhesive. The second adhesive is semi-cured by heating and pressing. A third adhesive is,applied to the piezoelectric elements, and a movable electrode frame having a plurality of movable electrodes is placed on the third adhesive. The third adhesive is semi-cured by heating and pressing. Next, a fourth adhesive is applied to each of the movable electrodes, and a hinge plate frame having a plurality of hinge plates is placed on the fourth adhesive. The fourth adhesive is semi-cured by heating and pressing. Finally, the adhered laminate thus obtained is placed in a heating furnace, and is heated at a predetermined temperature for a predetermined period of time, whereby each of the adhesives is fully cured.

An optical module has a substrate having a substrate surface provided with terminal pads and landing pads, and an optical element package having terminals and mounted on the substrate surface with a gap formed therebetween. The gap between the optical element package and the substrate surface is determined by the landing pads when the optical element package is mounted on the substrate surface. The terminal pads and the landing pads are exposed in a state where the optical element package is mounted on the substrate surface, and the terminal pads are electrically connected to corresponding terminals by solder.
摘要:
An optical module is produced by coating, with respect to a substrate having a substrate surface provided with terminal pads and landing pads a solder material on the terminal pads, mounting an optical element package having terminals and a flat top surface on the substrate using the landing pads so that the top surface becomes approximately parallel to the substrate surface and a gap is formed between a bottom surface of the optical element package and the substrate surface, preheating the terminal pads simultaneously as the mounting, and electrically connecting the terminal pads to corresponding terminals of the optical element package by melting the solder material and thereafter hardening the solder material.

A processing head is supported for pivotal movement around a pivot point in a processing apparatus. An urging member applies an urging force to the processing head at the pivot point. The processing apparatus allows establishment of point contact between the urging member and the processing head. When the surface of an object inclines from a predetermined attitude, the processing head is allowed to follow the inclination of the surface. The processing head is allowed to establish a predetermined attitude relative to the surface of the object. The processing head thus reliably enables a predetermined action to the object as desired.
