Abstract: PURPOSE:To realize a pin cushion shaped structure higher than conventional height without losing the high density packaging capacity, easy manufacturing, freedom of selection of materials connecting to two parts within a flip-chip mode connection structure. CONSTITUTION:The two metallic balls 8a, 8b overlapped in the vertical direction are arranged in a connection structure 2. The height is secured by the two overlapped metallic balls 8a, 8b while a low melting point solder layer 7 covering these metallic balls is solder connected between the two pads 6a, 6b so as to be firmly connected mechanically and electrically. At this time, the solder balls of low melting point solder coated metallic core are tack-fixed by the adhesive property of the flux coated on the whole surface of a package 4 and then molten down to form a solder bump. Likewise, the solder bump is formed on the pad 6b on the mother board 3 side. Finally, the pads 6a 6b are aligned with each other and re-fixed by solder reflow step while pressurizing in the overlapped direction to form a solder layer 7.

Abstract: PURPOSE:To suppress a phenomenon in which a developer after development is directly absorbed to sleeve, by providing a control plate of nonmagnetic matter at a developer collecting circuit. CONSTITUTION:Magnetic poles S3 and S4 of different polarities are distributed at a developing position (n) of a magnet roller 4A, and the development having a high edge effect is carried out by a magnetic brush which is formed centering on the  poles S3 and S4.
