Title: Manufacture of semiconductor package
Inventor: YAMAMOTO TETSUYA
IPC: H01L23/50
Filed: 1988-12-31
Abstract: PURPOSE:To prevent the board of a semiconductor package from cracking at the time of caulking, by joining a soft metal to the head tip of a pin to be jointed to the board. CONSTITUTION:Metal softer than the metal of a pin, silver solder for example, is soldered to the tip 10 of the pin 4, and it is caulked after insertion. The tip of the soft metal is caulked, spread transversely, and is joined to a board, so that the pin itself is not deformed and does not spread transversely. By pressing the head tip of the lead pin, in this way, to which a soft metal being softer than the lead pin has been jointed, the lead pin is fixed in a hole cut vertically through the semiconductor package board. And, this prevents the base board from cracking in the time of the caulking process of the pin tip.

The converter 15 varies the frequency according to the voltage level and increase the frequency when the input voltage rises to send a frequency division output to a frequency dividing circuit 6. The circuit 16 counts a current quantity which is converted into a frequency and the frequency. Then when a counted value corresponding to some large current quantity is reached, the circuit 16 sends it as an interruption signal to a CPU 17.

Abstract: PURPOSE: To execute composition without consuming time, cost and labor in the case of executing composition by using deformed characters having no font. CONSTITUTION: A CPU 100 reads out character data in each character from composition data stored in a composition data memory 300 and judges whether the sort of a corner 'em' or not based upon corner sort data in the read character data.

A character code corresponding to a combination between the 'em' character code and the corner sort and a condensed flattened letter rate are detected based upon the retrieval and read out from the corner transformation table.  The CPU 100 reads out font data corresponding to the character code read out from the corner transformation table from a hard disk 500 and deforms the font in accordance with the condensed flattened letter rate read out from the corner transformation table.
