Inventor: KOMORIDA YUTAKA
IPC: H05K3/38
Filed: 1989-10-12
Abstract: PURPOSE:To improve solder wettability and adhesion property and prevent reduction in heat dissipation property accompanying swelling or adhesion failure by forming a groove at least on the surface of the adhesion surface side with another member out of the surfaces of a metal circuit board which is directly joined to a ceramic circuit board. CONSTITUTION:In a printed-circuit board 1, a metal circuit board 3 consisting of copper is directly joined onto the surface of a ceramic printed-circuit board 2 consisting of a non-oxide material such as AlN and SiC or an oxide material such as Al2O3 and BeO. Then, a groove 4 is formed on this surface. The plane pattern of the groove 4 is in a constant-width stripe shape but may be in a grid-like pattern. When bonding other components to this metal circuit board 3 through solder, the wettability and adhesion property of solder become superior owing to the increase in the surface area by the groove and the anchor effect, thus achieving an accurate and positive adhesion. Also, air bubbles which are mixed to the adhesion interface part on adhesion are discharged to the outside readily along the groove, thus eliminating the problem of reduction in heat dissipation property accompanying swelling of the composition plane and adhesion failure.

IPC: H01H35/00
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To provide an operation panel input device excellent in durability, causing no deterioration in appearance of an operation panel. SOLUTION: In an operation panel 3, plural operation detection units U are disposed, and each operation detection unit U is composed of a light emitting means 5 to emit light of a light detection signal of a specific frequency through a light transmitting part of the operation panel 3 outward, and a light receiving means 6 to receive light of the light detection signal received through the light transmitting part from the outside.
