A shadow mask for deposition onto the active area of pixels for Ossila standard OLED/OPV substrates (S171). Used for depositing metal oxides or other materials onto the ITO (only over the active pixels). Available both with and without a 200 μm spacer to separate the substrate from the mask, to help avoid contact scratches and allow out-gassing of residual solvent from polymer layers.
Update: As part of our product improvement program, we have decided to simplify the masks available. Each type of mask is now available as a two-sided mask. On one side, a spacer and substrate holder are welded to the mask, and on the other, just a substrate holder. This will make both options available for our customers to to test out if they are uncertain which is best suited for their work. It also means you only need to purchase a single mask (rather than two) if you would like to use both systems.
Please note that the single-sided masks are only available while stocks last. However, if you are concerned that the double sided masks will be too thick for your evaporator, please do get in touch as we will be happy to help with this.
|Size||75 mm x 75 mm|
|Thickness||1.2 mm (without spacer) or 1.4 mm with spacer (excluding bolts)|
|Substrate capacity||12 substrates (S171)|
Mask with 200 μm spacer: For normal thermal evaporation systems we recommend the use of masks with the 200 μm spacer to help avoid scratches and allow better out-gassing.
Mask with direct contact: For sputtering and other non-directional deposition systems, as well as for thermal deposition systems with oblique angles or a very short throw, we recommend the use of the direct contact mask to get well-defined edges.
