4 results about "Active surface" patented technology

A strengthened window-type semiconductor package is provided. A substrate having an opening is mounted with at least a chip in a manner that, an active surface of the chip covers and partly exposed to the opening, and electrically connected to the substrate by bonding wires formed through the opening. An elastic non-conductive material is applied over the chip exclusive of the active surface. An upper encapsulant is formed to encapsulate the chip and the non-conductive material, and a lower encapsulant is formed to encapsulate the bonding wires and seal the opening. With provision of the non-conductive material for encapsulating the chip before forming the upper encapsulant, the chip can be prevented from cracking particularly at corner and edge positions that encounter relatively greater thermal stress during subsequent fabrication processes such as curing of the upper encapsulant and thermal cycles.

The invention discloses a textile support fixing device, which comprises a cylinder, a movable shaft is fixedly connected to both sides of the cylinder, a movable sleeve is movably connected to the surface of the movable shaft, and a movable sleeve is movably connected to the bottom of the movable sleeve. A fixed block, the inside of the fixed block is movably connected with a rotating shaft, the surface of the rotating shaft is movably connected with a snap ring, the top of the snap ring runs through the fixed block and extends to the outside of the fixed block, the inner wall of the snap ring It is movably connected with the surface of the movable shaft, both ends of the rotating shaft pass through the fixed block and extend to the outside of the fixed block, and a square is fixedly connected to the front of the fixed block. The present invention makes the textile support easy to use by arranging movable sleeves, fixed blocks, rotating shafts, clasps, squares, square frames, pressing blocks, grooves and ropes, and does not need to spend a lot of time when maintaining and replacing the drums, and can The replacement of the drum is directly completed, which is beneficial to people's use.

An odor masking tablet composition includes a solid single-use tablet comprising at least one base oil, a reactive agent, a base material, and an emulsifier. The tablet is packaged for individual use and transportation, or multiple tablets are packaged together. The tablets function to rapidly dissolve when deposited into toilet water and produce an active surface barrier for trapping unpleasant odors within the water. The tablets also include a scented material, and a coloring agent for changing the color of the water to which the tablet is placed.
