Abstract
A contact element suitable for SMD printed circuit boards is made of a flexible blank of sheet metal of approximate C-shaped cross-sectional configuration, with dimensions of a DIL package for SMD integrated circuits. The contact element is provided with bent terminals which are soldered onto respective bonding pads upon the circuit board while the top surface of the contact element is provided for contacting by a resilient external countercontact.
Claims5
A contact element for use with a printed circuit board with surface mounted device (SMD) components, for external contacting at the SMD component side, said contact element having dimensions of a dual in-line package (DIP) for SMD integrated circuits and being provided in form of a blank of sheet metal of approximate C-shaped cross sectional configuration, with a substantially flat top surface defining the sole contact area for a mating contact and with slotted sides representing a plurality of terminals which include opposing end portions coextensive with the circuit board for sole attachment of said contact element onto bonding pads provided on the circuit board by soldering, said top surface having opposing ends which are bent to define opposing sides which extend downwards in a direction of said terminals and have a length less than the plurality of said terminals.
A contact element for attachment on a printed circuit board, comprising a substantially flat top surface defining the sole contact area for a mating contact and with slotted sides representing a plurality of terminals which include opposing end portions coextensive with the circuit board for sole attachment of said contact element onto bonding pads provided on the circuit board by soldering, said top surface having opposing ends which are bent to define opposing sides which extend downwards in a direction of said terminals and have a length less than the plurality of said terminals.
A method of mounting an electric component to a circuit board, comprising the steps of:
- providing a contact element of approximate C-shaped cross sectional configuration with opposing sides and a substantially flat top surface which defines the sole contact area for a mating electric component;
- providing the opposing sides with a plurality of slots to define a plurality of terminals with bent end portions arranged coextensive with the circuit board, with the top surface having opposing ends which extend downwards in a direction of the terminals and are spaced from the top surface of the circuit board;
- and
- soldering the bent end portions of the terminals onto bonding pads on the circuit board.
