摘要:
The method involves superimposing two layers, and metallizing two faces of each layer. An interlayer made of metallized thermoplastic material e.g. liquid crystal polymer, is arranged between the two layers. Holes are pierced within the two layers before the two layers are placed in contact with each other, and within the interlayer. The holes are metallized. A metal is applied on openings of the holes of the two layers, and another metal is applied on openings of the holes of the interlayer. The two layers and the interlayer are pressed for diffusion bonding of zones covered with the metals. An independent claim is also included for a printed circuit board comprising two superimposed metallized layers.

L'invention vise un procédé de réalisation d'une carte imprimée (ClM) comprenant au moins deux couches superposées, métallisées sur leurs deux faces, et au moins une couche intercalaire disposée entre deux couches métallisées successives. On réalise chaque couche intercalaire à l'aide d'un matériau thermoplastique métallisé.
