Title: Method and apparatus for machining ceramic green sheet
Inventor: NAKAZAWA CHIKASHI
IPC: B23K26/08
Filed: 1999-10-22
Granted: 2001-04-01
Abstract: This invention is to provide a novel machining method whereby the machining for forming a matrix of through-holes or recesses, etc., on a ceramic green sheet by the laser beam irradiation can be executed at a high speed. While a motor 14 rotates a drum 11 at a predetermined rotation speed, a laser beam LB is intermittently irradiated on a green sheet GS laid on the outer side of the drum to form rows of through-holes arranged at equal spacings in the circumferential direction through the green sheet GS. Just before every revolution of the drum 11, a linear motor 19 shifts the drum 11 by a specified distance in the drum center line direction to form a row of through- holes at equal spacings in a direction perpendicular to the row of through-holes, thus forming a desired matrix of through-holes through the sheet GS.

When the lead frame is placed into the mold for package resin formation, the edge of the mold runner in the package mold will touch the resin embankment to prevent the package resin from overflowing to a wire bond area formed by the upper surface of the leads and resin embankment and upper surface of the chip. A package resin is formed onto the lead frame to expose the upper surface of the chip and the wire bond area of the leads through the opening of the package resin. Then, a semiconductor chip is pasted to the upper surface of the chip cavity and wiring is used to connect the chip with the wire bond area of the leads. A covering lid is placed on the opening of the package resin to complete the packaging process of the semiconductor package.

The transmission mode detector then detects the transmission mode by a mode detect unit according to the period of the envelope signal. If the detected mode is mode II or III, then the mode detecting unit further distinguishes the transmission mode based on the auto-correlations of the OFDM data symbol.
