Patent JP-H01218092-A (JP)
Title: Manufacture of printed wiring board
Inventor: IBARAKI MASAYUKI
IPC: H05K3/34
Filed: 1988-02-26
Abstract: PURPOSE:To prevent bridge soldering from being defective by forming a dam whose thickness is equal to the thickness of a resist between adjacent portions of the conductive film in which the soldering resist is filmed so as to cover the conductive film. CONSTITUTION:A soldering resist 12 is covered so that a conductive film 11 corresponding to electronic component leads which are formed at a narrow pitch is exposed. A part of the conductive film 11 is on a lower level compared to the surface of the surrounding soldering resist 12, so that dams D are formed between the adjacent conductive film portions as much as the thickness of the resist. Then, the reflow soldering is performed after first applying a soldering paste on the part to be soldered on the conductive film 11 having the dams D formed and then mounting the component leads 13 on the corresponding conductive film portions. The dams D prevent the melted solder 14 from being overflown from the conductive film 11, thereby preventing bridges from being defective when the adjacent conductive film portions are soldered.

Title: Semiconductor laser device
Inventor: KURODA TAKAROU
IPC: H01S5/00
Filed: 1983-03-18
Abstract: PURPOSE:To enable to manufacture the titled device with good yield at a time of crystal growth by periodically varying the width of the stepwise difference of a stripe active layer in a specific range. CONSTITUTION:A groove or a projection is formed on a semiconductor substrate 1. In this case, the depth of the groove or the height of the projection is set at 0.2-0.5mum and the center value W of the width of the groove or the projection at 2-5mum. Besides, the stripe width is periodically varied in the range of + or -0.2- 0.5mum from the center value along the direction of photo propagation. Such a formation causes the scattering loss the light receives to become extremely large even when the stepwise difference itself is very small, and enables transverse basic mode oscillation stable with the inhibition of high degree mode even when the width (w) is enlarged. Further, the element of excellent performance can be manufactured with good yield by one time crystal growth.
