Does the IPC-1752 date field have to be updated each year even if there has been no change in materials?
The date field in the IPC-1752A update schedule/expectation is not a requirement of the standard itself but subject to business relationship expectations (i.e. what a customer expects). In many cases, the industry expects declarations to be updated every year, otherwise they cannot be certain if materials have changed or not.
