    Abstract: A soil layer detection drilling device includes a drilling cylinder, and a soil-sampling assembly is provided inside the drilling cylinder. When the soil is drilled, equipment is in a vertical state, a controller is turned on to control a rotary motor to rotate, and the drilling cylinder is driven to drill the soil with the cooperation of drive wheels and a drive belt. Four slide blocks are evenly distributed around an outer circumference of a sliding disk and are matingly connected with slide grooves provided on an inner wall of the drilling cylinder, so when the drilling cylinder rotates, the soil-sampling assembly also rotates. A conical head first in contact with the ground starts to drill the ground, then the drilling cylinder gradually drills into a soil layer, and the drilling cylinder is idled as the drilling cylinder arrives at a certain depth, to clear soil on auger blades.

  • Patent number: 11289409
    Abstract: A method for fabricating a carrier-free semiconductor package includes: half-etching a metal carrier to form a plurality of recess grooves and a plurality of metal studs each serving in position as a solder pad or a die pad; filing each of the recess grooves with a first encapsulant; forming on the metal studs an antioxidant layer such as a silver plating layer or an organic solderable protection layer; and performing die-bonding, wire-bonding and molding processes respectively to form a second encapsulant encapsulating the chip. The recess grooves are filled with the first encapsulant to enhance the adhesion between the first encapsulant and the metal carrier, thereby solving the conventional problem of having a weak and pliable copper plate and avoiding transportation difficulty. The invention eliminates the use of costly metals as an etching resist layer to reduce fabrication cost, and further allows conductive traces to be flexibly disposed on the metal carrier to enhance electrical connection quality.

  • Patent number: 9190296
    Abstract: A semiconductor package without a chip carrier formed thereon and a fabrication method thereof. A metallic carrier is half-etched to form a plurality of grooves and metal studs corresponding to the grooves. The grooves are filled with a first encapsulant and a plurality of bonding pads are formed on the metal studs. The first encapsulant is bonded with the metal studs directly. Each of the bonding pads and one of the metal studs corresponding to the bonding pad form a T-shaped structure. Therefore, bonding force between the metal studs and the first encapsulant is enhanced such that delamination is avoided. Die mounting, wire-bonding and molding processes are performed subsequently. Since the half-etched grooves are filled with the first encapsulant, the drawback of having pliable metallic carrier that makes transportation difficult to carry out as encountered in prior techniques is overcome, and the manufacturing cost is educed by not requiring the use of costly metals as an etching resist layer.

  • Patent number: 8977871
    Abstract: A system comprises a plurality of processor cores. The processor cores may comprise one or more application processor (AP) cores and a boot strap processor (BSP) core. A basic input/output system (BIOS) comprises an I/O device module to call a stall function in response to an I/O operation, a power management module that couples to the I/O device and a timer module that couples to the power management module. The power management module is to adjust a timer period of the timer module based on a stall delay of the stall function. The power management module may hook the stall function and compare the stall delay with a predetermined threshold and set the timer period to the stall delay in response to determining that the stall delay is longer. The power management module may put the BSP in a sleep mode during the timer period to save power.
