PROBLEM TO BE SOLVED: To provide a multilayer interconnection structure using a LCP dielectric layer and a method for forming the structure. SOLUTION: Each of a first and second LCP (liquid crystal polymer) dielectric layers is bonded directly to each of a first and second opposed layers of a heat conduction layer without an extrinsic adhesive material that bonds the heat conduction layer to either of a first and second LCP dielectric layers. Alternatively, each of a first and second 2S1P substructures is bonded directly to each of a first and second opposed layers of a LCP dielectric bonding layer without an extrinsic adhesive material that bonds the LCP dielectric bonding layer to either of the first and second 2S1P substructures.

PROBLEM TO BE SOLVED: To provide a multi-layered structure using an LCP dielectric, and a forming method therefor. SOLUTION: A page is created by stacking N (N≥2) sub-structures in a certain arrangement order. The first sub-structure of each of a pair of adjacent sub-structures includes an LCP (liquid crystal polymer) dielectric material which is coupled to the second sub-structure of the pair of adjacent sub-structures. The page is brought into a temperature lower than the lowermost nematic-isotropic transition temperature of the LCP dielectric material in the page. Retention time and high pressure are adequate for plastically deforming all the LCP dielectric materials in the page, and laminating each of the pair of adjacent sub-structures without using an extrinsic adhesive layer which is arranged between the first and second sub-structures of each of the pair of adjacent sub-structures.

Abstract:
A method and apparatus for forming a security enclosure having improved fold retention. In particular, the enclosure is formed by folding a flexible tamper responde nt cloth around an electronic assembly. An adhesive on the inner folded surfaces of the cloth temporarily retains the folds. The enclosure is then exposed to heat and pressure to promote improve d adhesion strength of the adhesive, thereby improving told retention.
