Technical guides
Practical guides for purchasing, QA/ESD and production teams at electronics factories in Vietnam — how to set up an EPA, choose ESD flooring and workbenches, select gloves by process step, test ESD materials to ANSI/ESD S20.20 and pack moisture-sensitive parts. Every article is written by the PRIMEAG engineering team from ten years on factory floors, not translated from a catalogue.
