UNSPSC 32131021: Low temperature co fired ceramic substrate

Multilayer structure to provide the connections for electronic circuits, similar to printed circuit boards, that are joined just prior to firing. It is fired at lower temperatures allowing co-firing with conductive materials such as silver and gold and allowing the inclusion of components such as resistors into the package.

UNSPSC 32131021 Low temperature co-fired ceramic substrate is a Commodity code, but the recent state and local contract opportunities posted under this code do not reflect purchases of ceramic substrates or related materials. The five opportunities on record span custom printed circuit boards (University of Wisconsin-Madison), law enforcement equipment through a multi-state cooperative (Sourcewell), school district safety and security systems including alarms and access controls (Sarasota County, Florida), electrical parts and supplies (City of Phoenix), an industrial AC drive module (Riverside County, California), and city-wide printing and mailing services (City of Madison, Wisconsin). None of these solicitations explicitly name ceramic substrates as a commodity being procured. The code shows minimal or misaligned recent activity relative to its nominal scope.

Issuing bodies include a state university system, a state-authorized cooperative purchasing vehicle serving multiple jurisdictions across multiple states, a county school board, a city public works department, a county water authority, and a city administration office. Geographic distribution spans Wisconsin, Minnesota and Washington state (through the Sourcewell cooperative), Florida, Arizona, California, covering a broad geographic range without concentration in any single region. The mismatch between the code's named commodity and the actual solicitations suggests this code may not be the appropriate taxonomy classification for the work state and local governments are currently posting, or that recent opportunities have been incorrectly tagged at the procurement-system level.
