Ubiquitous communication systems for the electronics production industry: extending the CAMX framework

In order to standardize communication interfaces for the electronics assembly industry, the IPC/CAMX standards have been developed. CAMX proposes standard messages defined in XML that are exchanged through Web-based message oriented middleware. A key feature of the CAMX standards is that they are extensible, enabling the implementation of enhancements while maintaining backwards compatibility. In particular, enhancements to the CAMX communications protocol to enable graceful scalability of the communications framework are possible, through the use of architectures involving server clustering or distributed systems. Data exchange can also be secured by the use of authentication and encryption mechanisms. Additionally, quality of service guarantees can be provided to enable deterministic real-time delivery of data. Discovery of devices and extended capabilities could also be enabled by using Web semantic techniques
