Latest Patents

One of Tsurushima's latest patents is an "Apparatus for forming spherical electrodes." This invention relates to a method and apparatus for forming ball electrodes on electrode pads provided on a package. The design allows for high precision alignment of solder balls with electrode pads, thereby reducing processing costs. The installation apparatus for the solder balls is preferably made of heat-resisting glass or other transparent materials, allowing for observation during the process. The solder balls are aligned with the electrode pads and brought into contact, with the entire process being viewable from the top. A light beam is then radiated through the installation apparatus, melting the soldering paste on the electrode pads and fixing the solder balls in place, resulting in precisely formed ball electrodes.

Another significant patent is the "Outer lead bending apparatus for a semiconductor package device." This apparatus consists of a fixed unit and a movable unit that can move toward and away from each other. It includes a first die that holds the semiconductor package in place and a second die that bends the outer leads of the semiconductor package into a specified configuration when the movable unit is driven toward the fixed unit.
