Title: Method of replacing semiconductor element
Inventor: TAKADA NORIMASA
IPC: H05K3/34
Filed: 1988-02-17
Abstract: PURPOSE:To perform replacement of semiconductor elements at a high yield rate and to increase the manufacturing yield rate, by removing a semiconductor element from a substrate, forming a thin film having good solder wettability on a silicon plate, pushing said thin film to a semiconductor-element mounting position, heating the silicon plate or the substrate in this state, and absorbing the remaining solder on the substrate into the thin film on the silicon plate. CONSTITUTION:A substrate 1 on which a defective semiconductor element 3 is mounted is placed on a hot plate 4 and heated. The semiconductor element 3 is removed from the substrate 1. A gold thin film (described as Au film hereinafter) 7 is formed on a silicon plate 6. The Au thin film 4 is pushed to the mounting position of the semiconductor element 3, where solder remnant 5 remains, with a pushing jig 8. Then, heating is performed under the state wherein the silicon plate 6 is pushed. The solder remnant 5 on the substrate 1 is absorbed into the Au film 7 on the silicon plate very excellently because the Au thin film 7 has excellent solder wettability and the flatness of the silicon plate 6 is good. Then, another semiconductor element 9 for replacement is mounted on the substrate 1 and connected to the remaining solder 5' through a solder bump 2.

Abstract: PROBLEM TO BE SOLVED: To efficiently obtain VICS information and DGPS information by selecting DGPS information providing station and selecting the station of a frequency stored as the frequency of a VICS information providing station as soon as finishing the correction of a present position by DGPS information. SOLUTION: DGPS information is obtained from a tuned DGPS information providing station (S46).

Thus, at the time of investigating an extracting position on the frame and storing it in a memory at the time of first extracting DGPS information from FM multiplexed data, an extracting time after this can be reduced. Next, it is judged whether the correction of a present position is completed or not based on DGPS information obtained at S46, and the judement is continued until its result becomes Yes (S47). Next, a VICS information providing station is tuned based on data recorded as the frequency of the VICS information providing station stored at S42 as soon as the correction is finished.
