A circuit board connector has a fixing member for a housing on a circuit board. The socket is equipped with at least a double break radius crimp, on its outside surface and extending into said interior space to define a double crimp beam. Drive current is monitored and a signal proportional to the current is produced for the purpose of analyzing current profiles as part of the test regimen for the device under test. These techniques may be used alone, or preferably, used on combination with one another. Generally, the steeper the depression wall, the more strength is provided to the structure.
