Title: Method and device for supplying solder to printed board
Inventor: MASUDA SADAO
IPC: H05K3/34
Filed: 1994-11-30
Abstract: PURPOSE: To supply solder even to a printed board mounted with surface mounting parts by transferring the solder to the board after respectively transferring required amounts of solder to the front end sections of heated pins composed of material having high solder wettability by dipping the pins in a molten solder bath. CONSTITUTION: Molten solder is transferred to the front end sections of heated pins 7 heated to a required temperature by means of a heating device 6 by dipping the pins 7 in the molten solder contained in a molten solder bath by lowering a pin holder 5. When the pins 7 are dipped in the solder bath, the front end sections of the pints 7 are only coated with required amounts of solder, because the front end sections are made of material having high solder wettability and the other sections of the pins 7 are coated with material which repels solder. Then the pins 8 are raised from the solder bath and the solder adhering to the front end sections of pins 7 is transferred to the land sections 2 of a board 3 by moving the pins 7 to positions above the land sections 2 of a board 3 and lowering the pins 7.  The land sections 2 of the substrate 3 are formed of a material having higher solder wettability than the front end sections of the pins 7 so that the solder can be easily transferred to the sections 2.

Title: Pattern forming method
Inventor: FUKUDA HIROSHI
IPC: G03F7/038
Filed: 1991-11-14
Abstract: PURPOSE:To enable a pattern in a specific shape and having a satisfactory sensitivity to be formed even during the exposure step using soft X-ray by a method wherein an energy beam-electron beam conversion layer efficiently producing the electron beams from the energy beams is provided on a resist film sensitive to the electron beams. CONSTITUTION:An X-ray-secondary electron conversion film 3 efficiently producing the secondary electrons by X-ray irradiation is provided on a resist film 2 sensitive to the electron beams applied on a substrate 1 to be processed. When multilayered resist structure is selectively irradiated with soft X-rays 4, the X-ray-secondary electron converted film 3 on the part irradiated with the soft X-rays absorbs the soft X-rays to emit abundant secondary electrons 5. The electron beam resist 2 is sensitized by the secondary electrons 5. Since the energy of the secondary electrons 5 is low, the region 6 only near the uppermost surface of the electron beam resist film is sensitized. Through these procedures, a pattern in a specific shape can be formed.
