Title: Method and structure for mounting of surface mounting lsi package
Inventor: TANIGAWA YUKIHIKO
IPC: H05K3/34
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To easily perform the alignment operation of an LSI package with a printed-circuit board and to easily inspect the alignment operation by a method wherein, when the LSI package is bonded to the printed-circuit board, a lead protruding part is aligned with a solder recessed part. SOLUTION: Every lead 2 at an LSI package 1 is structured so as to have a lead protruding part 3. A solder part 4 is formed on every pad 6 at a printed- circuit board 7. Then, the LSI package 1 is positioned in such a way that the lead protruding part 3 is overlapped with every solder recessed part 5 by a mounter. Then, when their overlapped part is observed, their alignment operation is inspected. After that, the LSI package 1 is bonded to the printed-circuit board 7 via a reflow treatment process and a cooling process. Thereby, the alignment operation of the LSI package 1 can be achieved simply. In addition, the mounting yield of the LSI package 1 onto the printed-circuit board 7 can be enhanced.

Title: Impedance adjustment circuit for 2-wire subscriber line
Inventor: YAMAURA YUTAKA
IPC: H04M1/76
Filed: 1989-05-11
Abstract: PURPOSE:To automatize the impedance adjustment by connecting plural balancers to a 2/4-wire conversion hybrid sequentially and selectively and using a detection section to a detect a detouring signal from an oscillating section simultaneously and setting this signal to an minimum level automatically. CONSTITUTION:A balancer section 2 constituted of (n) relays RL1-RLn driven selectively with a control section 4 and (n) balancers B1-Bn, which are connected selectively to a 2/4-wire conversion hybrid 1. A CPU 41 in a control section 4 sends an in-band signal to the oscillation section 3 at the reception side. The signal is detoured to the 4-wire transmission side due to the mismatching of the 2-wire side impedance of the 2/4-wire conversion hybrid 1. The detouring level is detected by a detection section 5 and an A/D converter 42 in the control section 4 converts the analog signal level into a digital signal and sends it to the CPU 41. The CPU 41 drives the relays RL2-RLn of the balancer section to connect the balancers B2-Bn switchingly and selects any of the balancers B1-Bn whose level gives an optimum level.
