Abstract: A connector for connecting an implement to a digger or other prime mover is mountable on the digger and has a recess for receiving a connecting pin mounted on the implement. The connecting pin is retained in the recess by a retaining pin that is mounted on the connector. The retaining pin has a head that is seated on a face of the recess and a cylindrical tail portion that is received in a passage formed in the connector to secure the retaining pin on the connector with the head projecting into the recess adjacent the connecting pin. There is clearance between the head and the connecting pin and the head is shaped so that the clearance is reduced to a minimum when the retaining pin is rotated in the passage. The connector advantageously comprises spaced apart side walls joined together by across member in the form of a bent plate.

Abstract: A new test method to quantify capillary flow solderability on a printed wiring board surface finish. The test is based on solder flow from a pad onto narrow strips or lines. A test procedure and video image analysis technique were developed for conducting the test and evaluating the data. Feasibility tests revealed that the wetted distance was sensitive to the ratio of pad radius to line width (l/r), solder volume, and flux predry time.
