Abstract
A production line environmental stress screening system consists of a shaker, a head expander, a fast ramping temperature chamber, two transporting trays, two PCB according fixture assemblies, a vacuum pump, a compressed air system, and a base table. The two PCB according fixture assemblies move back and forth and alternately enter the fast ramping temperature chamber to receive vibration and high and low temperature screening. This system will greatly reduce the screening time required, drastically increase the production efficiency and significantly reduce the screening cost.
