Title: Solder
Inventor: IWASAKI KENJI
IPC: B23K35/14
Filed: 1985-09-17
Abstract: PURPOSE:To execute laser soldering by using a laser device of a low output by containing a photoabsorbing member in a solder base body which is melted by using a laser beam as a heat source. CONSTITUTION:A solder 4 to be used is blackened by mixing amorphous carbon (graphite)4B into a paste-like solder (solder body) 4A by a solvent such as acetone, alcohol, etc. This blackened paste-like solder 4 is stuck to a soldering part of electronic parts 1B from a solder supply device 3, and a laser beam is radiated to the soldering part from a leading-out tip part 2C of a laser device 2. By this laser beam, the soldering part is heated and also the blackened paste- like solder 4 is melted, and by this molten solder 4, the soldering part is soldered. Since this solder 4 is blackened, a light absorptivity of the laser beam is high, and heating is obtained enough by the laser beam of the laser device 2 of a small output.

Abstract: PURPOSE:To prevent an intrusion into an opening section owing to wettability with a cover member of excess sealing glass by forming an absorbing section for excess sealing glass around the opening section. CONSTITUTION:The sealing structure of a member in which an opening section 20 for a member 10 is sealed with a plate-shaped member 40 by glass 30 for sealing is formed. An absorbing section 50 for glass for sealing excess glass is shaped around the opening section 20 for said member 10. When a proper quantity or more of sealing glass 30 is applied, excess sealing glass 30 is absorbed by the excess absorbing section 50 when the chamferred section 50 is shaped, and the tangential direction of a contact section R1 with the member to be sealed 10 of the sealing glass 30 is inclined in the direction opposite to the opening section 20 more than a perpendicular (f) forming the opening section 20. That is, the surface R1 on the opening section 20 side of the sealing glass 30 is recessed in the direction opposite to the opening section 20 more than the perpendicular (f). Accordingly, the quantity of intrusion S1 to the opening section 20 of the sealing glass 30 is reduced only by a section where the surface R1 is retreated in the direction opposite to the opening section 20. That is, an extent that the excess sealing glass penetrates into the opening section is reduced even in a section where a proper quantity or more of sealing glass is applied.
