    • A tin-silver coating for use with circuit boards, which can include a conductive circuit with an exposed surface disposed on a substrate. The tin-silver coating covers the exposed surface of the conductive circuit. The conductive circuit can include electrical traces, contact pads and vias, each of which may include or be formed of copper. In one embodiment, the tin-silver coating can include a tin weight percentage between 85 and 99.5%, while the silver weight percentage can be between 0.5 and 15%. In one embodiment the tin-silver coating can be between 35 and 60 millionths of an inch. A barrier plate may also be included between the conductive circuit and the tin-silver coating.

    • An electrosurgical device comprising: an electrode having a first portion whose exterior is electrically uninsulated, a second portion whose exterior is electrically insulated, and a third portion; an elongated hollow body having an internal cavity, a front end, a rear end, an external surface, and an electrical wire arranged within the body. The hollow body is configured to reversibly receive the third portion of the electrode at the front end of the body such that electrical contact is made between the electrode and the electrical wire and the second portion of the electrode is not surrounded by the hollow body. A first button is provided for controlling a current flow at a first level to the electrode and is arranged on the external surface. A vacuum tube is slidably engaged by the body and has an inlet generally facing the front end and adjacent the electrode. A vacuum outlet port is arranged near the rear end of the body, and the outlet port, internal cavity, and vacuum inlet are in fluid communication with each other.

    • A surface mount connector for circuit board attachment is provided in the form of an elongate pin with a head or base formed at the lower end of the pin. The base has a bottom surface that extends substantially normal to the axis of the pin and is dimensioned to be positioned on, and soldered to, a pad on a primary circuit board. A solder bond is achieved by re-flowing a quantity of solder applied to the pad along with a quantity of flux before placing the base on top of the quantity of solder. The base is formed with a plurality of channels that open through the bottom surface and through a peripheral wall of the base for permitting gases generated by vaporizing the flux during solder re-flow to escape from underneath the base and to increase the strength of the solder bond between the pad and the base. Exhaustion of the gases prevents undesirable skating of the connector and misalignment and eliminates voids in the solder bond that would otherwise weaken the bond.
    • 用于电路板连接的表面安装连接器以细长销的形式提供,其头部或底部形成在销的下端。 基座具有基本上垂直于销的轴线延伸的底表面,并且尺寸设计成定位在主电路板上的焊盘上并焊接到主电路板上的焊盘。 通过在将基底放置在焊料量的顶部之前,将一定数量的焊料与一定量的焊剂一起重新流动,来实现焊接接合。 底座形成有多个通道,该通道穿过底部表面并穿过底座的周边壁,用于允许在焊料重新流动期间汽化助焊剂而产生的气体从底部下方逸出并增加焊料的强度 垫与基座之间的接合。 气体的耗尽可防止连接器的不希望的滑冰和不对准,并且消除焊料接合中的空隙,否则会削弱接合。
