  • Publication number: 20240105642
    Abstract: A method of manufacturing a package structure at least includes the following steps. An encapsulant laterally is formed to encapsulate the die and the plurality of through vias. A plurality of first connectors are formed to electrically connect to first surfaces of the plurality of through vias. A warpage control material is formed over the die, wherein the warpage control material is disposed to cover an entire surface of the die. A protection material is formed over the encapsulant and around the plurality of first connectors and the warpage control material. A coefficient of thermal expansion of the protection material is less than a coefficient of thermal expansion of the encapsulant.

  • Patent number: 8105100
    Abstract: The power converter of the invention includes a housing, two conductive pins, a flexible arm and a plug. The housing has a recess. The conductive pins protrude from the recess. The flexible arm is formed with a protrudent plate and a positioning block, which protrude from the recess. The protrudent plate is located beside the conductive pins. The plug includes a disk and two leads. The protrudent plate presses either of the conductive pins when the flexible arm is depressed so that the conductive pins move away from the leads to form a disconnection. The conductive pins connect to the leads when the disk is positioned by the positioning block.

  • Publication number: 20100039754
    Abstract: A sliding structure includes a stator, a slider, and a plane spring. The slider is slidably disposed on the stator. The plane spring is interposed between the stator and the slider. The plane spring includes two spiral portions which curl into two inverse directions towards two center portions. The two center portions of the plane spring are respectively fixed to the stator and the slider so that the plane spring is capable of pushing the slider to slide to one of two maintaining positions in a latter half of a slide operation between the two maintaining positions.
