How this was counted
Counted from the MPBxChange plant register: one record per bare-board fabrication site in Thailand, each traced to public sources such as company announcements, stock exchange filings, Board of Investment approvals and the Thai company register. Assembly-only sites are not counted. A plant that has left no public trace is missing here, so read every count as "at least".
