The PCB Connector as a Surface Mounted Device

Abstract

The problems and solutions relative to the design of PCB connectors for surface mounting are explored. The systems approach is discussed because surface mount technology (SMT) for connectors is largely driven by the need for minimum labor, and automated production lines. Therefore, the design must consider the application of the connectors by robots. This in turn brings about the need to consider how to package the connectors for presentation to the robot, how to identify the connector, and how the connector can be picked Up by the robot arm, consistentlY. Once on the board, the effect of large mating and unmating forces must be brought into the equation. The connector must be held down by some mechanical means, which must also be compatible with the capabilities of the robot. These problems are all explored. Answers to the design Problems are put forth, the conclusion being that all technologies are presently available to make the SMT connector a viable product family.
