Title: Solder particle, solder paste, manufacture of solder particle and method of mounting device on circuit board
Inventor: SATO KAZUNORI
IPC: B23K35/14
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of defect in wire bonding by forming solder particles flat in shape so that no particles are rolled easily with the wind or the like, and generating a state where the surfaces of the particles are in contact with each other so that no particles are blown away or rolled over by a hot blast even if they are exposed from a solder paste layer. SOLUTION: A solder paste containing flat-shaped solder particles 11 is printed on a conductor layer on a wiring board, with devices temporarily fixed on the conductor layer, and then with the wiring board brought in a reflow furnace, preheating is performed by a hot blast. Since the flat solder particle 11 has a large contact surface, they stick to each other through a viscous compound in the solder paste to form a large mass, which therefore is hard to be blown away and rolled over by a hot blast. In manufacturing the flat solder particles 11, the solder particles in a quantity capable of monodispersion are sprayed on a press surface and given vibration in a horizontal direction, so that the spherical solder particles are crushed through press working by lowering the upper part of a metallic die, thereby forming the flat solder particles 11.

Filed: 1985-04-24
Abstract: PURPOSE:To reduce the overhead of a processing using a bit map by retrieving one or more bit trains of a certain state at high speed and having an instruction which sets and resets the bit train having an optional position and optional length. CONSTITUTION:A bit train having the continuous '0' state of the length equal to the contents (n) of a counter register 33 is retrieved out of the contents of a bit map 10 having the length equal to the contents (m) of a size register 32 shown by R3 starting at the addresses shown by B2 and D2 of an instruction register 31. Then the position of the retrieved bit train is stored in a register 36. An initial value (m-n) is set first to a counter 34. An AND is obtained between the left (n) bits of a register 35 having all '1' larger than (n) and a bit map 10. The map 10 is shifted right by a bit to obtain an AND again if the result of the first AND is not equal to '0'. The operation of the AND is repeated until the result is equal to '0'. The operation of the AND is repeated until the result is equal to '0'. Thus it is possible to retrieve the map 10 and to set and reset a bit train just with a single instruction. This can reduce the overhead.
