A first substrate, having an evacuation port, and a second substrate are bonded together with a first sealing material in a frame shape interposed between them to create an internal space. The internal space is evacuated through the evacuation port, and the evacuation port is sealed up with the internal space kept evacuated. At this time, a second sealing material inserted into the evacuation port is heated and melted while being pressed toward the second substrate such that the evacuation port is sealed up with the second sealing material melted. The evacuation port and the second sealing material have dissimilar shapes when viewed along the center axis of the evacuation port in a state where the second sealing material has been inserted into the evacuation port but has not melted yet.

Certain example embodiments relate to an insulating glass (IG) unit. A spacer system is interposed between first and second substrates. The spacer system helps to maintain the first and second substrates in substantially parallel spaced apart relation to one another, and to define a cavity between the first and second substrates. A desiccant material is located in a body of the spacer system, with the desiccant material comprising a desiccant matrix and a molecular sieve replacement material formed for adsorption at a relative humidity of 10-20%. The molecular sieve replacement material may be a salt or other material (such as, for example, MgCl.sub.2, CaCl.sub.2, CaO, MgSO.sub.4, and/or the like). The cavity may be primarily filled with an inert gas (such as Ar, Kr, Xe, or the like) or a reactive gas (such as CO.sub.2). An electrostatically-driven dynamic shade may be provided in the cavity.

An insulated glass assembly line generally includes a first and second automated lite picker, a washer, a vertical gas filling and wetting station, a robot, and an applicator station.

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 pillar delivery method is a method for delivering a plurality of pillars onto a substrate, including a glass panel, to manufacture a glass panel unit. The pillar delivery method includes an irradiation step, a holding step, and a mounting step. The irradiation step includes setting, over a holder, a sheet for use to form pillars and irradiating the sheet with a laser beam to punch out the plurality of pillars. The holding step includes having the plurality of pillars, which have been punched out of the sheet, held by the holder. The mounting step includes picking up some or all of the plurality of pillars from the holder and mounting the pillars onto the substrate.
