Improved methods, systems, and apparatuses are disclosed for testing LGA devices. Specifically, the additional piece of glass is mounted at an angle to the panes of the window pack, with the angled glass diverging farther from the window pack at an upper section than at a lower section. In this connection, the present invention adopts a net of an expanded metal structure which serves as both means for preventing the scatter of broken pieces of a lamp upon burst of the lamp and an air deflecting plate facing a portion to be cooled. An integrated access-privilege set is generated and used as a single source to authorize access to a database regardless of whether database internal or external accounts are used to access the database. The air distribution system is connected to the air inlet for receiving air from the air inlet, and is operative to pass the air over multiple surfaces of the bonding stage for the purpose of temperature control.
