Abstract: The present invention improves upon the existing touch based systems by introducing new mechanisms of interaction with the user that can improve the productivity of users that are creating and modifying diagrams and figures on such touch based systems. More specifically, without leaving the draw grid, the invention allows the user to seamlessly copy one or more objects, delete one or more objects, change the type and end type of a connector between two objects, change the color of an object, and create a sequence diagram. The above mentioned control gesture operations do not require the user to click or select a button that is outside the draw grid to achieve a particular control objective.

Abstract: An assembly, and an associated method, facilitates egress of gasses generated during a solder process, thereby reducing the occurrence of voids in the resultant solder connection. A channel is formed to extend part way through a solder pad. The channel defines a path by which to facilitate the egress of the gas generated during the solder operation.
