Title: Printed wiring board and its manufacture
Inventor: KARIYA TAKASHI
IPC: H05K1/09
Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To increase the insulation between conductor circuits and reduce the cost and shorten the time for delivery by allowing metal nuclei to chemically bind with the surface of a resin insulating layer, or physically implanting metal nuclei into the surface and forming conductive circuits constituted of a plated film bound with the metal nuclei on the resin insulating layer. SOLUTION: A copper-clad laminate made by laminating a copper foil 2 on a resin substrate 1 is drilled for holding and inner wall faces of the holes are treated with a modifiyer formed of organometal sodium to improve the wettability of the surface of the substrate. Then, palladium-tin colloid is deposited to the entire surface of the substrate to form an electroless plating film and then an electrolytic copper plating film. Thereafter, the substrate is oxidation-reduction treated to form a roughed layer 4 on the entire surface of a conductor including through holes 3 and then the surface of the substrate is planarized, and a plalladium colloid catalyst is applied to form an electroless copper plating film 6.  By this method, the insulation reliability between conductor circuits can be obtained and a printed wiring board can be made at low cost, and the time for delivery can be shortened.

IPC: F04F10/00
Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To eliminate the particular necessity of motive power such as electricity, simplify a structure, reduce failure, and reliably actuate it by opening an opening-closing valve of an air sucking tube by rotating a flap installed on a rotary shaft in a siphon tube by a counterflow. SOLUTION: A flap 2 is installed on a rotary shaft 3 inside of a siphon tube 1. The rotary shaft 3 vertically penetrates through the siphon tube 1, and is turnably supported by a bearing 4, and is connected to an arm 6 whose upper end transmits rotation as a horizontal directional movement. An air sucking tube 12 whose inside is communicated with the external atmosphere is erected on a top part of the siphon tube 1, and an opening-closing valve 5 is arranged on the opening end. A valve body of the opening-closing valve 5 is fixed to the tip of the arm 6, and a plate thickness directional inclination is arranged on an end surface opposed to a counterflow of the flap 2. When the counterflow is caused, since an inclination is arranged in the plate thickness direction in the flap 2, torque by backward flowing fluid force is generated.  The arm 6 rotates with the rotary shaft 3 as the center correspondently to a turning angle of the flap 2, and the opening-closing valve 5 is opened.
