Abstract
In one aspect, a surface mount contact is provided for attachment to a circuit board or the like. The contact includes an elongated electrically conductive pin that has a first end and an opposing second end. A pre-formed heat re-flowable material is attached to one end of the pin and a conductive locator member surrounds the pin at a location between the first and second ends thereof and adjacent the conductive locator member. In one embodiment, the locator member is in the form of a cylindrical collar that extends around the pin.
Claims16
A surface mount contact for coupling to an electronic device comprising:
- a conductive pin having an elongated body including a first end and a second end;
- a heat re-flowable bonding member coupled to the first end;
- and a conductive substrate disposed around the conductive pin between the first and second ends and adjacent the heat re-flowable bonding member, wherein the substrate is a collar that radially protrudes from the pin and has an opening through which the pin extends and a surface thereof that is adjacent the heat re-flowable bonding member is conductive, wherein the second end of the pin has a head formed thereat for placement against a conductive surface and wherein the dimensions of the head are either substantially equal to dimensions of the conductive substrate or the dimensions of the head are greater than the dimensions of the conductive substrate.
A surface mount contact for coupling to an electronic device comprising:
- a conductive pin having an elongated body including a first end and a second end;
- a heat re-flowable bonding member coupled to the first end;
- and a conductive locator member disposed around the conductive pin between the first and second ends and adjacent the heat re-flowable bonding member, wherein the locator member is a collar that radially protrudes from the pin and has an opening through which the pin extends and a surface thereof that is adjacent the heat re-flowable bonding member is conductive, wherein the locator member has a first face and a second face with the first face having a recessed section.
A surface mount contact for coupling to an electronic device comprising:
- a conductive pin having an elongated body including a first end and a second end;
- a heat re-flowable bonding member coupled to and being separate from the first end such that the heat re-flowable bonding member extends about at least a surface of the first end;
- and a conductive locator member disposed around the conductive pin between the first and second ends and immediately adjacent the heat re-flowable bonding member, the conductive locator member being movable along a longitudinal length of the conductor pin, wherein at least a first surface of the conductive locator member comprises a conductive profiled surface that is a non-wettable surface positioned such that it faces and is in intimate contact with the heat re-flowable bonding member.
A method of forming a solder ball on a surface mount contact for coupling to an electronic device, the method comprising:
- providing the surface mount contact;
- the surface mount contact including a conductive pin having an elongated body including a first end and a second end and a conductive locator member that has a through opening for receiving the pin;
- forming a concave shaped recess in a first surface of the conductive locator member, with the opening extending through the concave shaped recess, wherein at least the first surface is a non-wettable surface;
- inserting the pin through the opening so that at least the first end thereof extends beyond the first surface of the conductive locator member;
- placing a mass of heat re-flowable bonding member within the concave-shaped recess about the first end of the pin;
- and reflowing the heat re-flowable bonding member so that the heat re-flowable bonding member flows into a spherically-shaped body that forms about and attaches to the first end of the pin.
