    摘要: The present disclosure relates to a method of manufacturing a vacuum insulated glass unit (200). The method comprises providing a first glass sheet (2) comprising a first major surface 2a, and distributing a plurality of spacers (3) onto the first major surface (2a), wherein the spacers (3) comprises a ferromagnetic material. The distribution of the plurality of spacers (3) comprises dropping spacers (3) from a spacer holder (9, 30) from a distance above the first major surface (2a) and towards an intended spacer position (IP). Each, dropped spacer (3) comprises predefined, oppositely directed contact surfaces (3a, 3b). The spacer (3) has a maximum spacer width (W1)that is at least 1.1 times larger than the maximum spacer height (H1). A magnet arrangement (100) is arranged opposite to the second major surface (2b). The magnet arrangement (100) comprises one or more magnets (10). The magnet arrangement (100) forces the dropped spacer (3) to be orientated with one of said contact surfaces (3a, 3b) facing the first major surface (2a), so that the contact surface (3a, 3b) rests on the first major surface (2a) at the intended spacer position (IP).

    摘要: Provided are a glass panel unit and a method for manufacturing the glass panel unit, both of which are designed to overcome the problem of poor handleability of known glass panel units with no through holes. A glass panel unit (10) includes a first panel (20), a second panel (30), a seal (40), and a boundary wall (42). The seal (40) has a frame shape and hermetically bonds respective peripheral edge portions of the first panel (20) and the second panel (30). The boundary wall (42) partitions an internal space (500) into a first space (510) as a hermetically sealed evacuated space (50) and a second space (520) spatially separated from the first space (510). The first panel (20) has a first through hole (25) provided through a portion, corresponding to the second space (520), of the first panel (20). The second panel (30) has a second through hole (35) provided through a portion, corresponding to the second space (520) and facing the first through hole (25), of the second panel (30).
