The PCBAs must be protected from one another. They must never be stacked up without suitable rigid mechanical protection. Comply with the special product specification if any (container drawing, logistic sheet, use of drying agent...) The PCBAs dimensions must fit the size of the container (packaging) which provides board protection. This reduces all stresses on the PCBAs which could damage them (relative displacement of PCBAs in an over large container or compression of PCBAs in an excessively small container). Each intermediate container should contain only one type of PCBA The PCBAs must not be damaged when they are presented for acceptance. Overall packaging must be strong enough to protect the PCBAs against all risk of damage (falls, projection...)
