Printing Technology / Screen for the Printing - Precision Emulsion Screens

All our emulsion screens are ideal for use in advanced metallization processes. Precise material control and deposition accuracy, with the screens being produced in a Class 10,000 Clean Room with exceptional environmental and process control.

During the production process there is zero contamination and all screens are dimensionally stable.

  • Emulsion thickness 0 - 50µm ± 2µm; 51 - 100µm ± 5µm; 101 - 500 µm ±10%; 501 - 1000µm ±15%
  • Line widths from 25 µm
  • Maximum Frame size 1000 x 1000mm O/D
  • Rigorous inspection throughout the production cycle
  • Accurate verification against source data
  • Wide range of input data formats accepted
  • Premium dispatch service available on request (conditions apply)
  • Quality production and rapid turnaround

Fine line stencils

  • An increase in cell efficiency of more than 0.2% is possible, in comparison to the industry standard single screen print process.
  • Printing of front side grids with 40µm fingers, resulting in reductions of silver paste use of up to 40%, and absolute values as low as 68 mg/cell.
  • Fine Line Stencil™ can be used with printers other than those manufactured by ASM
  • The only additional knowledge required is an awareness of the process parameters and a few points on housekeeping.
  • Stencils of any standard size from 355 x 355 mm and larger can be supported. (contact ASM AE regarding other requirements)
  • Fine Line Stencil™ has a useful working life of up to 20,000 print cycles
  • Stencil thicknesses from 25µm up to 200µm are available with opening widths from 25µm upwards
  • Standard PV wafer sizes of 125mm and 156mm are easily accommodated with no lower limit on wafer size and an upper limit of 220mm for special applications
