From a PCB fabricator’s perspective, epoxy resin supply chain issues are of indirect concern as they become a subset of laminate quality, supply, and cost considerations.
Semiconductor fabs like to avoid writing custom software to fit all of the idiosyncrasies of individual processing systems. So HP developed PC-10 to handle IC process equipment by separating it into general classes. SECS II was a mandatory prerequisite of the equipment before an interface to PC-10 could be developed.
