Abstract
A button contact and array of button contacts are provided for surface mounting a leadless IC device to a circuit board. The button contacts of the button contact array have a substantially flat body lying in a plane and oppositedly directed contact points protruding from resiliently deflectable contact support arms of said body. The button contacts of the invention, which provide a low profile contact between surface mounted components, are suitable for high frequency applications, and particularly high frequency test and burn-in applications, and are relatively durable.
Claims17
A button contact for surface mounting an IC device to a circuit board, said button contact comprising
- a body lying in a plane and having opposed contact faces, said body providing a conductive path between the contact faces thereof, and
- at least one contact point protruding from at least one of the opposed contact faces of said body, said contact point acting to outwardly extend the conductive path between the contact faces of said body in a direction generally perpendicular to the plane of said body and being inwardly displaceable toward the plane of said body.
A button contact for surface mounting an IC device to a circuit board, said button contact comprising
- a substantially flat body lying in a plane and having opposed contact faces, said body including at least one resiliently deflectable contact support arm, and
- a contact point protruding from said contact support arm,
- said contact support arm being resiliently deflectable to permit said contact point to be displaced toward to the plane of said body, and
- said body providing a conductive path between the opposed contact faces of said body and said contact point acting to extend said conductive path in a direction perpendicular to the plane of said body.
A button contact for surface mounting an IC device to a circuit board, said button contact comprising
- a substantially flat electrically conductive body lying in a plane and having opposed contact faces, said body including a perimeter portion and first and second resiliently deflectable contact support arms extending inwardly of said perimeter portion, and
- a contact point protruding from each of said first and second contact support arms, the contact point on said first contact support arm being oppositely directed from the contact point on the said second contact support arm,
- said contact support arms being resiliently deflectable to permit said contact points to be displaced toward the plane of said body.
A button contact array for surface mounting an IC device to a circuit board, said button contact assembly comprising
- a thin flexible insulator backing lying in a plane and having a first side and a second side,
- a plurality of button contacts secured to the first side of said base to provide an array of electrically conductive contacts, each of said button contacts comprising
- a substantially flat body lying substantially in the plane of said film insulator backing and having opposed contact faces, said body providing a conductive path between the contact faces thereof, and
- oppositely directed contact points, one of said contact points protruding from each of the opposed contact faces of said body, said contact points acting to extend the conductive path between the contact faces of said body in a direction perpendicular to the plane of said body and being displaceable in relation to the plane of said body,
- said thin insulator backing having etched out portions at the point of securement of each of said plurality of button contacts to expose the contact points thereof on the second side of said insulator backing.
