A surface mount contact for coupling to an electronic device , comprising: a conductive pin having an elongated pin body , the pin body comprising a first end at the top of the pin body and a second end opposing to the first end ; and a heat re-flowable bonding member coupled to the first end ; wherein the pin body is integrally provided with a support portion in a region of the pin body adjacent to the heat re-flowable bonding member , and wherein the support portion : extends radially from the pin body , and is in a shape of ring and centrally located in the pin body and is located closer to the first end than to the second end ; and the support portion has a same diameter as an outer diameter of the heat re-flowable bonding member ; wherein the pin body has a shoulder protruding radially outward from the pin body , between the support function and the second end of the pin body ; characterized in that: the shoulder at a side close to the first end has a downwardly inclined surface with respect to a plane perpendicular to an axially extending direction of the pin body , which is formed by chamfering the pin body ; wherein the shoulder is in the form of two annular step sections , a first step section of which faces toward the first end and has a first outer diameter, and a second step section of which has a second outer diameter, wherein the first outer diameter is larger than the second outer diameter and in turn the second outer diameter is larger than an outer diameter of the pin body ; and the downwardly inclined surface is disposed at an upper portion of the first step section . a conductive pin having an elongated pin body , the pin body comprising a first end at the top of the pin body and a second end opposing to the first end ; and a heat re-flowable bonding member coupled to the first end ; wherein the pin body is integrally provided with a support portion in a region of the pin body adjacent to the heat re-flowable bonding member , and wherein the support portion : extends radially from the pin body , and is in a shape of ring and centrally located in the pin body and is located closer to the first end than to the second end ; and the support portion has a same diameter as an outer diameter of the heat re-flowable bonding member ; wherein the pin body has a shoulder protruding radially outward from the pin body , between the support function and the second end of the pin body ; characterized in that: the shoulder at a side close to the first end has a downwardly inclined surface with respect to a plane perpendicular to an axially extending direction of the pin body , which is formed by chamfering the pin body ; wherein the shoulder is in the form of two annular step sections , a first step section of which faces toward the first end and has a first outer diameter, and a second step section of which has a second outer diameter, wherein the first outer diameter is larger than the second outer diameter and in turn the second outer diameter is larger than an outer diameter of the pin body ; and the downwardly inclined surface is disposed at an upper portion of the first step section . the shoulder at a side close to the first end has a downwardly inclined surface with respect to a plane perpendicular to an axially extending direction of the pin body , which is formed by chamfering the pin body ; wherein the shoulder is in the form of two annular step sections , a first step section of which faces toward the first end and has a first outer diameter, and a second step section of which has a second outer diameter, wherein the first outer diameter is larger than the second outer diameter and in turn the second outer diameter is larger than an outer diameter of the pin body ; and the downwardly inclined surface is disposed at an upper portion of the first step section . <EOS>
