Abstract

The present disclosure relates to a method of manufacturing a vacuum insulated glass unit. The method comprises providing a vacuum insulated glass unit assembly (1) comprising a first glass sheet (2) and a second glass sheet (3), a plurality of support structures (5) distributed in a gap (6) between a first major surface (2a) of the first glass sheet (2) and first major surface (3a) of the second glass sheet (3), a peripheral edge seal (4) which is configured to seal the gap (6), wherein the first glass sheet (2) comprises a through hole (10), wherein the through hole (10) extends between the first major surface (2a) and a second, oppositely directed, major surface (2b) of the first glass sheet (2). A cover (20) is provided. The cover comprises a covering body (21) and a solidified seal material (22), The solidified seal material may comprise glass solder material. The solidified seal material is attached to the covering body (21, 21a) and encompasses the through hole (10) in an uninterrupted manner. The cover is arranged so that the solidified seal material (22) is placed between a surface part (2sp, 10s) of the first glass sheet (2) and the covering body (21), and so that the covering body (21) covers at least a part (10a) of the through hole (10). The gap (6) is evacuated by means of a pump (30), so that gas (GA), such as air, in the gap (6) is evacuated through the through hole (10). The solidified seal material (22) is heated by means of a heater (7) so as to soften the solidified seal material, thereby providing that the softened seal material (22) adhere to the surface part (2sp, 10s) of the first glass sheet (2) around the through hole (10). The softened seal material (22) is cooled so as to harden the softened seal material, thereby sealing the evacuated gap (6). The evacuation of the gap (6) by means of the pump (30) may comprise that the gas (GA) is evacuated from the gap (6) through one or more gas passages (25), wherein the one or more gas passages (25) is/are arranged between said surface part (2sp, 10s) of the first glass sheet (2) and a surface (22a) of the solidified seal material (22) which faces said surface part (2sp, 10s) of the first glass sheet (2).
