Title: Solder land for chip component
Inventor: ABE YOSHINOBU
IPC: H05K1/11
Filed: 1990-02-17
Abstract: PURPOSE:To prevent the generation of Manhattan phenomena and facilitate visual inspection of the quality of soldering by forming a land projection section which extends from chip components so that the width may be narrowed compared with the land width of a land main body which responds with a soldered part of the chip component. CONSTITUTION:A pair of solder lands 11 which respond with a pair of soldered parts of a chip component 3 is formed on a substrate in projected shape. The solder lands 11 are formed so that the land width 13w of a projected part 13 which extends from the chip component 3 may be narrowed in contrast with the land width 12w of a land body 12 formed in the same shape with the soldered part 4 of the chip component 3. Therefore, a Manhattan promotion moment based on the surface tension of molten solder acting between the soldered part 4 of the chip component 3 and the land projection part 13 of the solder land 11 is reduced by a reduced portion of the land width 13. In addition, the moisturized state of the solder land 11 is confirmed at the land projection part 13. This construction makes it possible to prevent the generation of Manhattan phenomena and facilitate visual inspection of the quality of soldered parts.

Filed: 1985-02-28
Abstract: PURPOSE:To attain efficient missing data retransmission even with a delay on a line by providing a means returning code information corresponding to area information to a transmission side and requesting the retransmission of the area information and a means setting variably the criterion for retransmission request so as to set permissible retransmission request. CONSTITUTION:Since a line number is added after the 'EOL' (line end code) by the modified Huffman code or the modified read code, the condition for retransmission request is set optionally by a reception side. When an error takes place only at one line at the reception side, for example, it is discriminated as the excellent reception and the retransmission request is applied after a consecutive error of >=2 lines takes place. In applying the retransmission request above, for example, a line number is sent at each line from the transmission side and the reception side changes the algorithm for discrimination of received picture defect. In applying the change in various conditions as above, the consecutive permissible error line is set optionally.
