Firing System SS-550-PVX

Full automatic Screen printing/Drying/Firing System SS-550-PVX
(Loader → backside Ag electrode printing → drying → backside Al electrode printing → drying → flipping → front side Ag electrode printing → drying → firing → un-loader)
 
  • Integrated Visual positioning and visual chipping/breaking detection minimizes stress on cells.
  • Compatible with 550mm square screen frames for printing on large sized substrate.
  • High-accuracy printing head capable of printing fine line and higher film thickness.
  • Can be set up with automatic paste feeder.
  • can be combined with our original drying furnace and firing furnace to create an electrode metallization line.

Near Infrared Firing Furnace

Sales point

Near Infrared Drying furnace

Sales point

  • Using near IR lamps allows short time drying.

Specifications

  • Transfer method : Mesh-belt, Walking beam, Tray transfer, etc.
  • Standard use temperature : 150~250°C
  • Maximum set up temperature : 350°C

Wafer/Cell transfer loading machine

  • Reciprocal replacement transfer of wafers or cells in coin stack magazines and slotted cassettes.
  • Automatic supply of cassette to next processing system after transfer is possible.

Wafer/Cell packaging machine

  • Shrink-wrap packaging of wafer or cells in fixed units using thermal shrink film.
  • Increased packaging efficiency and prevent oxidization, reduced breakage for shipping to distant customers.

Conductive Paste For Solar Cell

Metalization

Silver paste for front side
