Abstract:
A printed circuit assembly includes a base printed circuit having a printed circuit receiving area and a plurality of electrical contacts provided on the printed circuit receiving area. The printed circuit assembly also includes a secondary printed circuit having a secondary substrate including a mating edge and a plurality of secondary contacts provided along the mating edge. The secondary printed circuit is mounted on the base printed circuit such that the mating edge of the secondary printed circuit is directly engaged with the base printed circuit at the printed circuit receiving area. Each of the secondary contacts is electrically connected to a corresponding one of the electrical contacts of the base printed circuit.
Abstract:
A light emitting device, in which an encapsulation resin is disposed at a space confined between an optical member and a mounting substrate. This encapsulation resin is possibly made free from a void-generation therein. In this light emitting device, the optical member can be precisely positioned. An electrode disposed outside a color conversion member is possibly free from an improper solder connection. A ring gate is formed on the top surface of the mounting substrate outside of the optical member, and acts to position the color conversion member. The ring gate acts to prevent an overflowing liquid encapsulation resin from flowing to the electrode provided. The ring gate is provided with a plurality of centering projections which are spaced circumferentially along its inner circumference to position the color conversion member.
Abstract:
The present invention relates to an interconnection system of a first substrate (1) comprising at least one first transmission line (3) with a second substrate (10) comprising at least one second transmission line (11), the orientation of the first substrate with respect to the second substrate being arbitrary. The first substrate (1) comprises at least one metallized hole at one extremity of said first line and the second substrate (10) comprises a projecting element extending said second line and a ground saving, said projecting element being inserted into the metallized hole. The invention notably applies in the domain of microwaves and can interconnect a substrate comprising a printed antenna with a substrate receiving the processing circuits of the signal.
