TEKA: Optimizing PC/104 Interconnects with A Choice of Solderless or Self-Soldering Solutions
 
WARWICK, RI - The PC/104 architecture is based around an evolutionary roadmap that provides universal building blocks for embedded applications as well as a highly configurable solution for emerging technology requirements. Its stackable bus structure with predefined pin-outs ensures interoperability across different manufacturers, while providing inherent ruggedness and reliability to support a wide range of applications, including ruggedized military systems, aerospace, telemetry, industrial equipment, communications, automotive, and many more.

As the name implies, the PC/104 computer bus uses 104 pins. These pins include all the normal lines used in the ISA bus, with additional ground pins added to ensure bus integrity. Signal timing and voltage levels are identical to the ISA bus, with lower current requirements.

Over three decades of development, the PC/104 architecture has also been adapted to support a growing range of other standards, including PCI and PC Express, through PC/104 variations such as PC/104-Plus, PCI-104, EBX and EPIC.

Just as the PC/104 standard allows a wide range of choices for system-level configurations, designers of board-level solutions and sub-system modules also have choices about how best to implement the PC/104 connectors on their products.

This
Tech Bulletin provides an overview of the options available for implementation of PC/104 bus interconnects as well as other interconnects on PC/104 assemblies, such as I/O edge-mount connectors, with a focus on both solder-free and self-solder alternatives.
