What does reflow mean? - definitions

Webthe substrate was conducted in a five-zone reflow oven. The glass interposer with flux dipping was properly aligned onto the substrate and subsequently reflowed for soldering. The reflow profile had a peak temperature of 245°C and a dwell time of 60 seconds above liquids; this ensured that the soldering between glass interposer and substrate ... WebAs a premetal dielectric, borophosphosilicate glass (BPSG) has been widely used for device planarization. Device evolution towards smaller feature size and restrictions on BPSG reflow temperature budget make a void-free BPSG gapfill a challenging task. This work investigates the extendibility of the current BPSG process ... screven school system
