A PCB's "assembly layer" is not a single layer, but a system of layers critical for manufacturing. This system includes the silkscreen for component labels, the solder paste layer for SMT, the solder mask to prevent shorts, and a surface finish for solderability. These layers work together to guide the PCB assembly process.

Proper PCB/PCBA packaging is crucial, preventing physical, ESD, and moisture damage to ensure ultimate product reliability and performance. Key materials like ESD bags, Moisture Barrier Bags, desiccants, and HICs safeguard quality, prevent defects like delamination, and minimize issues, protecting electronic investments from production through to final application.
