Process for securing a microwave module to a support
View Patent ↗The present invention relates to a process for securing to a metal support at least one microwave electronic module made on a substrate one of whose faces forms an earth plane. The process consists in depositing between the face forming the earth plane and the metal support, at least one strip of conducting adhesive at the level of the zones of breakage of the earth plane. The invention applies to the microwave field.
1. Process for securing to a metal support at least one microwave electronic module made on a substrate one of whose faces forms an earth plane, comprising a step of depositing one strip of conducting adhesive between the face forming the earth plane and the metal support only at a level of zones of breakage of the earth plane, to obtain earth continuity, said zones of breakage being at points of transition between a first mode of propagation and a second different mode of propagation, the other parts of the earth plane being formed without adhesive deposited thereon.
2. Process according to claim 1 , characterized in that the conducting adhesive is a one- or two-component conducting epoxy adhesive.
3. Process according to claim 2 , characterized in that the conducting adhesive is laden with conducting particles such as silver or gold.
4. Process according to claim 1 , wherein the conducting adhesive is deposited by using screen-printing deposition or deposition by syringe.
5. Process for securing to a metal support at least one microwave electronic module made on a substrate one of whose faces forms an earth plane, comprising a step of depositing one piece of a strip of conductive adhesive between the face forming the earth plane and the metal support at a level of zones of breakage of the earth plane to obtain earth continuity, said zones of breakage being at points of transition between a first mode of propagation and a second different mode of propagation, wherein additional pieces of the strip of conducting adhesive forming a mechanical reinforcement are deposited between the face forming the earth plane and the metal support, the other parts of the earth plane being formed without adhesive deposited thereon.
6. Process according to claim 5 , wherein the additional pieces of the strip of conducting adhesive forming a mechanical reinforcement are deposited around the perimeter of the face of the module forming the earth plane.
7. Process according to claim 5 , characterized in that the conducting adhesive is a one- or two-component conducting epoxy adhesive.
