Abstract:
PROBLEM TO BE SOLVED: To provide a lightweight PCB assembly which provides a robust structural feature in order to satisfy a request for weight reduction. SOLUTION: In this multilayer microwave corrugated printed circuit board, a corrugated printed circuit board 100 includes an assembly 102 of a level 1, an assembly 104 of a level 2, and an assembly 106 of a level 3. The assembly 102 of the level 1 can include one or more openings, a radio frequency (RF) feed, an electronic component, and a power and communication signal. The assembly 104 of the level 2 can include an RF feed, an electronic component, and a power and communication signal. The assembly 106 of the level 3 can also includes an RF feed, an electronic component, and a power and communication signal. This method includes a step of connecting a first flexible layer and a second flexible layer to each other by a non-conductive adhesive layer arranged therebetween, and filling a first hole and a second hole with conductive paste for electrically connecting a first signal line to a second signal line.

Abstract:
PROBLEM TO BE SOLVED: To provide a rigid-board interconnection structure which gives a long bending life free from stress concentration in flexible boards when the flexible boards are bent. SOLUTION: First and second flexible boards 30, 40 are mutually glued with an adhesion layer 50 in the vicinity of interconnection portions of first and second rigid boards 10, 20 in such a way that the spacing between the first and second flexible boards 30, 40 is narrower than the thickness of the first and second rigid boards.

Abstract:
PROBLEM TO BE SOLVED: To provide a substrate with a multilayer interconnection structure in which the multilayer interconnection structure can be separated from the substrate in a simple, quick and economical manner, and to provide a manufacturing method therefor. SOLUTION: The substrate 11 is provided that has the multilayer interconnection structure 19 provided thereon. The multilayer interconnection structure 19 is adhered to the substrate 11 substantially only through partial regions thereof. The method of manufacturing and recycling such substrate, a method of packaging electronic devices using such substrate, and the method of manufacturing multilayer interconnection devices are also provided.
