Shenzhen Zhuolida Electronics Co., Ltd. [China]

Specification: 1.Used as machine parts 2. RoHS compliant 3. Chemical etched on stainless steel, high precision

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.

Reel-to-Reel Chemical Etching can creates highly-repeatable unstampable, burr-free components with complex features for intricate metal designs and shapes on a continuous metal strip made from wide variety of ferrous and nonferrous materials.

This process can hold very close tolerances, and extremely high level of repeatability, and true position from metal part to metal part. The degree of precision and consistency achievable offers a continuous chemically etched metal strip and a mass production advantage alternative to the standard panel or sheet etching process.
