Title: Method of testing reworked chip
Inventor: CAI MING-CHENG
IPC: G01R31/303
Filed: 1998-08-03
Granted: 1999-12-21
Abstract: The present invention is about a method of testing reworked chips. The chip has to be removed of all external packaging with the aid of a strong acid under high temperature. Then, a layer of double-side adhesive tape is placed on top of the chip covering all exposed areas after removal of external package and all sides around the chip. A ceramic cover is then firmly placed on top of the exposed chip to shield off intense heat and infrared light as the chip is being soldered onto printed circuit board. This is necessary in order to avoid any damage to the structure and functions of solder pad during the soldering operation. The design of the cover is such that it allows easy removal of the cover after the chip has been fixed on the printed circuit board thus facilitating inspection of the internal structure of the chip.

Title: Chip scale packaging method with a high efficient heat dissipation capability and the device manufactured by the same
Inventor: CHEN TZUNG-JIE
IPC: H01L23/28
Filed: 1999-02-12
Granted: 2001-04-21
Abstract: The present invention provides a chip scale packaging method with a high efficient heat dissipation capability which sequentially adheres a chip and a substrate to a heat dissipation base with a peripheral block wall. The dimension of the substrate is not larger than the chip scale, and the range of the electrical connection between the chip and the substrate will not exceed the chip scale. While performing a molding process, the sealing is filled between the substrate periphery and the block wall, wherein the block wall can prevent the mold from spilling. The metal balls are implanted on the of the substrate that is not covered by the sealing. The BGA packaging device formed by the process has an excellently high efficient dissipation effect due to the chip being directly adhered to the heat dissipation base. Furthermore, because the dimension of the substrate is not larger than that of the chip, the ratio of packaging device dimension to chip scale is below 1.2, which can satisfy the requirement of the chip scale package.
