Circuit assemblies can be electrically interconnected by providing a circuit assembly having a top surface, a bottom surface, and a perimeter edge connecting the top and bottom surfaces, the perimeter edge being formed of insulative material and having a plurality of conductive features embedded in and exposed on the surface of the edge. The conductive features are arranged in contact sets, and each contact set is separated from adjacent contact sets by a portion of the perimeter edge that is free of conductive features. Each contact set includes conductive features that together form a distributed electrical connection to a single node. The insulative material is selectively removed to form recesses adjacent the conductive features exposing additional surface contact areas along lateral portions of the conductive features in the recesses.

Method of forming an electrical connection to an electronic module

The invention features soldering parts (e.g., printed circuit boards) by indexing the parts sequentially and continuously through a series of processing stations. Flux may be applied to precise areas of the parts at a flux station, and the flux station may include a rough part locator that roughly locates a part indexed into the flux station and a precise part locator that precisely locates the part. The flux station may further include a guide rail for supporting the part and a mechanism for raising and lowering the guide rail. The flux station may include a flux sprayer for applying flux to the part, where the flux sprayer includes an air valve, a flux valve, and a controller coupled to activate and deactivate separately the air valve and the flux valve. The controller may activate the air valve before activating the flux valve and deactivate the flux valve before deactivating the air valve.

Soldering

The invention features soldering parts (e.g., printed circuit boards) by indexing the parts sequentially and continuously through a series of processing stations. Each of the series of processing stations includes at least one processing position, and the indexer indexes the parts from processing position to processing position. At different processing stations, the parts indexed into those processing stations are simultaneously processed.

Modular soldering nozzle

The automatic soldering of printed circuit boards wherein different boards can be simultaneously processed at different stations, e.g. a fluxing station, a preheating station and a soldering station. An identification station in advance of the fluxing station controls various parameters at the processing stations in response to board type as the boards are indexed through the various stations. Parameters such as location of application, time of application, pump speed etc. may be controlled in response to board type.
