A method for manufacturing a glass panel unit includes a glue arrangement step, an assembly forming step, a first melting step, an evacuation step, and a second melting step. The first melting step includes melting a hot glue, bonding a first and second panel with the glue, and forming an internal space. The first melting step includes a first temperature raising step, a first temperature maintaining step including maintaining the temperature of the assembly at a temperature equal to or higher than a softening point of the hot glue, and a first temperature lowering step, which are performed in this order. The first temperature lowering step includes: an anterior temperature lowering step including lowering the temperature of the assembly; a middle temperature maintaining step including maintaining the temperature of the assembly; and a posterior temperature lowering step including lowering the temperature of the assembly, which are performed in this order.

A gas adsorption unit includes a getter, a package encapsulating the getter, and a low-melting member. The low-melting member is heated, and thereby melted, at a temperature lower than a melting point of the package to bond a connector including the low-melting member onto the package. Next, the low-melting member that has melted is cooled and cured. Then, thermal stress resulting from a difference in thermal expansion coefficient between the package and the connector is caused to the package connected to the connector, thereby breaking the package open.

The vacuum insulated glazing comprises a first glass pane, having a first interior major surface and a first exterior major surface and a second glass pane having a second interior major surface and second exterior major surface, the glass panes being arranged in parallel with said interior major surfaces facing each other. The VIG unit further comprises a low emissivity coating deposited on at least the first interior major surface, an edge region in proximity to the edge of the first glass pane, defined as where none or a reduced part of the low emissivity coating is present, and a side seal comprising a glassy seal material arranged at a minimum separation distance (d1_min) from said low emissivity coating, so that an intermediate part of said edge region between said glassy sealing material and said low emissivity coating is not bonded to said glassy sealing material, or a side seal arranged at a minimum separation distance (d1_min) of at least 1.5 mm, such as at least 2 mm, or such as at least 3 mm from said low emissivity coating.

The present disclosure relates to a method of providing vacuum insulating glass (VIG) units each comprising at least a first and a second glass pane and a plurality of support pillars distributed between opposing surfaces of said glass panes to provide a gap (8) between the glass panes. A plurality of pane elements are provided, and individual topographic representations (TOPREP_2a TOPREP_2n) of each of said plurality of pane elements (2a-2n) are obtained based on input (4) from a measuring arrangement (3), and the topographic representations are stored in a data storage (DS). The stored topographic representations are processed and resulting surface distance characteristic between pairs of panes are estimated. Vacuum insulating glass (VIG) assemblies are thus provided based on estimated resulting surface distance characteristics. The present disclosure additionally relates to a system.

A method for manufacturing a glass panel unit includes an assembling step, a bonding step, a gas exhausting step, a sealing step, and an activating step. The bonding step includes melting a peripheral wall in a baking furnace at a first predetermined temperature to hermetically bond a first glass pane and a second glass pane together with the peripheral wall thus melted. The gas exhausting step includes exhausting a gas from an internal space through an exhaust port in the baking furnace to turn the internal space into a vacuum space. The sealing step includes locally heating to a temperature higher than a second predetermined temperature, and thereby melting, either a port sealing material or an exhaust pipe to seal the exhaust port and thereby obtain a work in progress. The activating step includes activating a gas adsorbent after the sealing step to obtain a glass panel unit.
