Controller interface and process for assembly thereof

Interface (100) according to one of the preceding claims, wherein the screen (110) comprises an overstructure (150) having an outer surface which defines the front face (110a) of the screen (110) and an inner surface, opposite to the outer surface, on which the operative layer (111) is formed by means of silkscreen printing.

Interface (100) according to the preceding claim, wherein the screen (110) comprises a light-impermeable masking layer covering the inner surface of the overstructure (150) and the operative layer (111), whereby the masking layer does not cover the first contacts (111b) so that they are joined to the second contacts (120a) directly by means of the conductive adhesive (140).

Interface (100) according to one of the preceding claims, wherein the first contacts (111b) and/or second contacts (120a) are configured to project inside the openings (130a) following coupling of the screen (110) and electronic device (120) to the frame (130).

Interface (100) according to one of the preceding claims, wherein the first contacts (111b) are adjacent to each other along the back face (110b) of the screen (110) and the second contacts (120a) are positioned adjacent to each other in a mirror arrangement on the electronic device (120), the conductive adhesive (140) being divided into portions each of which places a first contact (111b) in contact with a corresponding second contact and is physically and electrically separated from other portions which place additional first contacts (111b) in contact with corresponding second contacts (120a).

Process for manufacturing an interface (100) comprising:

• a step A involving the formation of a screen (110) of the interface (100), an electronic device (120) and a frame (130) apt to connect together the screen (110) and the electronic device (120), wherein the screen (110) has first contacts (111b) exposed on a back face (110b) thereof and the electronic device (120) has second contacts (120a) which are positioned so as to correspondingly face the first contacts (111b), the frame (130) having openings (130a) positioned and configured such that, following coupling of the screen (110) and electronic device (120) to the frame (130), the first contacts (111b) and second contacts (120a) face each other through the openings (130a);
• a step B of applying a conductive adhesive (140) on the first contacts (111b), second contacts (120a) and/or inside the openings (130a);
• a step C of coupling the screen (110) and the electronic device (120) to the frame (130) such that the first contacts (111b) and second contacts (120a) are fixed together and electrically connected by the conductive adhesive (140), so as to form an interface (100) according to one of the preceding claims.

Process according to the preceding claim, wherein step B involves applying a portion of conductive adhesive (140) onto each first contact (111b), second contact and/or opening (130a), wherein said portion consists of an amount of conductive adhesive (140) sufficient for forming an electrical contact between a first contact (111b) and the corresponding second contact through a corresponding opening (130a) of the frame (130) following the execution of step C;

• wherein said amount of conductive adhesive (140) is limited such that each portion of conductive adhesive (140) is separated from the other portions so as not to generate electrical contacts between them.
