Specification and applications

The  shadow mask is designed for thermal evaporation of gates either above or below the source-drain contacts. The substrates are kept away from direct contact with the mask by use of a 200 µm standoff which prevents damage to delicate polymer layers and allows evaporation of any residual solvents while in vacuum chambers. 

Shadow mask is a thin metal film with between 800,000 and 1.6 million tiny holes, which act to form images on TV and computer screens. It is one of three core components of the Braun monitor that determines the clarity of color monitors.
Shadow mask accurately guides the electro beams (red, green, blue) projected by the electric gun in color monitors of TVs and computers to the fluorescent surface inside the panel. It is also capable of color distinction so that monitors can display clearer color images.

Zhuolida use the Photo Etching technology to make precision metal mask.

The Metal mask specification as follow:

1. position precision:no more than ±5μm

2.Roughness:no more than ±2μm

3. Metal thickness:0.02mm~1.0mm

4.Minimize hole size:100μm

5. Apply on any kinds of solder and different machines requirement.

6.The products with micro-vias have smooth edge,Electrolytic polishing process help fine pitch pattern demould easily.

7.Half-etching process can make STEP  UP/ STEP  DOWN mask.
