  • Patent number: 6371354
    Abstract: An apparatus for the temperature regulation processing of electronic components such as semiconductor circuits, printed circuit boards and the like comprises a temperature regulated housing through which the components are conveyed on carriers. The carriers enter through an inlet slot in the housing provided with temperature regulating members and are conveyed onto a magazine and then out through an outlet slot opposite the inlet slot once processing is complete. Inside the housing, the carriers are loaded on a progressively loaded magazine provided with adjacently arranged holders. Once all the holders are loaded, the magazine is filled and in an end position. The magazine is then displaced to its starting position in a fast reverse run. A new carrier is conveyed in through the inlet slot thereby causing the temperature regulated carrier occupying the holder to be conveyed out through the outlet slot.

  • Publication number: 20010001468
    Abstract: The invention relates to a method for the temperature regulation of components, for example semiconductor circuits, printed circuit boards and the like, in which the components are conveyed on carriers through an inlet slot into a temperature-regulating housing provided with temperature-regulating members and are conveyed out through an outlet slot opposite the inlet slot. The carriers are accommodated by a magazine in the housing, which magazine is provided with adjacently arranged holders and, after the first holder has been loaded, is displaced progressively in one direction from a starting position into successive accommodating positions in which the individual holders of the magazine are loaded one after the other.

  • Patent number: 6223975
    Abstract: A method and apparatus for the temperature regulation of components such as semiconductor circuits, printed circuit boards and the like. The components are conveyed on carriers through an inlet slot into a temperature regulating housing provided with temperature regulating members and are convey out through an outlet slot opposite the inlet slot. In the housing, the carriers are loaded on a magazine provided with adjacently arranged holders. After the first holder is loaded in the starting position, the magazine is displaced progressively in one direction into successive positions in which the remaining holders of the magazine are loaded one after the other. Once all the holders are loaded, the magazine is filled and in an end position. Thereupon the magazine is displaced back to its starting position in a fast reverse run in the opposite direction.
