Abstract:
Disclosed is a semiconductor package sorting method for improving sorting speed and yield of semiconductor packages. The method comprises performing a vision inspection on a tray, transferring the tray to a buffer unit, shifting defective products to a defective product tray, performing a vision inspection on a tray, transferring the tray to an unloading unit, determining whether defective products are found among semiconductor packages, if it is determined that the unloading tray receives defective products, shifting the defective products to the defective product tray and shifting normal products to fill the unloading tray, if a vision inspection for a last tray of a lot is completed, shifting the defective products to the defective product tray, discharging the defective product tray into a defective product storage unit, and if the re-inspection is determined, performing a defective product re-inspection simultaneously with arrangement of the normal products.
Abstract:
A method for inspecting a semiconductor device is disclosed, which increases the accuracy of an external- defect inspection capable of determining whether balls or PCBs (Printed Circuit Boards) of the semiconductor device have external defects. The method for inspecting the semiconductor device to determine whether a defect occurs in a ball grid array contained in a PCB via an image captured by a camera includes the steps of: a) capturing an image of the semiconductor device to allow a circumference of each ball contained in the semiconductor device to be displayed in white, and acquiring falling-illumination image information from the captured image; b) capturing an image of the semiconductor device to allow a center part of each ball contained in the semiconductor device to be displayed in white, and acquiring coaxial image information from the captured image; c) subtracting the coaxial image information from the falling-illumination image information, and acquiring ring-shaped image information; and d) comparing the ring- shaped image information with reference image information, and determining whether the ball is defective according to the comparison result.
Abstract:
Disclosed is a method for inspecting a flat panel. The method for inspecting the flat panel includes the steps of: arranging a camera at a measurement location of the flat panel by horizontally moving at least one of the flat panel and the camera; automatically focusing the camera with respect to a measuring target of the flat panel at the measurement location; acquiring a plurality of images for the measuring target by vertically moving the camera within a set region on the basis of the present location of the camera when focusing the camera; selecting the image having the most definition for the measuring target among the acquired images; processing the selected image; and determining whether the measuring target is defective or not.
Abstract:
The present invention relates to a harmful emissions reduction apparatus for an engine using a reformer, a reformer for the same, and a harmful emissions reduction method for an engine using the same. The harmful emissions reduction apparatus for an engine comprises: a reformer (20) which reforms oxygen (O) and hydrocarbons (HC) included in the exhaust gas from an engine into hydrogen (H2) and carbon monoxide (CO), and increases the temperature of the exhaust gas by exothermic reaction; an exhaust gas recirculation unit (EGR) (30) which supplies the engine (10) with the exhaust gas which was reformed by the reformer (20) to increase the hydrogen (H2) content, and stabilizes the homogeneous charge compression ignition (HCCI) combustion of the engine (10); a hydrocarbon-added selective catalytic reduction unit (HC-SCR) (40) which receives the exhaust gas which was reformed by the reformer (20) to increase the hydrogen (H2) content, and transforms the nitrogen oxide (NOx) into nitrogen (N2) and water vapor (H2O) using hydrocarbons as a reducing agent in a state that enhances the reduction reaction of the nitrogen oxide (NOx); and a diesel particulate filter (DPF) (50) which receives the exhaust gas which was reformed by the reformer (20) to increase the hydrogen (H2) content, and removes particulate matter (PM) deposited thereinside through oxidation. The harmful emissions reduction apparatus for an engine of the present invention treats the exhaust gas more efficiently as post-processing apparatuses such as the selective catalytic reduction (HC-SCR) and the diesel particulate filter (DPF) are interacting in addition to the application of the HCCI combustion and the reformer.
