Manual film tearing machine, suitable for tearing 6-inch small flat edge SIC wafer film. The main body of the machine is made of stainless steel and aluminum alloy, with stable performance and simple operation.

This equipment (lamator) is mainly used for 12 inch Si wafer BG film coating. No burrs, no bubbles. The wafer type is dummy wafer. This semi-automatic film sticking machine is suitable for applying film to products such as wafers, semiconductors, ceramics, and glass. It is a device used for film coating processing, specifically designed to precisely adhere thin film materials to the surface of wafers. It combines the characteristics of manual operation and automatic control, providing higher film application accuracy and efficiency while maintaining operational convenience.

This film tearing machine is used to remove the protective tape on the surface of wafers after thinning or etching processes. The device can be used for film tearing on 4 ", 5", 6 ", 8", and 12 "wafers.

The 1951 USAF resolution test chart is a resolution test pattern conforming to MIL-STD-150A standard, set by US Air Force in 1951. It is still widely accepted to test the resolving power of optical imaging systems such as microscopes, cameras and image scanners, although MIL-STD-150A was cancelled on October 16, 2006.[1] The pattern consists of groups of three bars (small Ronchi rulings) with dimensions from big to small. The largest bar the imager cannot discern is the limitation of its resolving power.

The common MIL-STD-150A format consists of six "groups" in three layers of patterns. The largest groups, forming the first layer, are located on the outer sides. The smaller layers repeat the same pattern but are progressively smaller toward the center. Each group consists of six elements, numbered from 1 to 6. Within the same layer, the odd-numbered groups appear contiguously from 1 through 6 from the upper right corner. The first element of the even-numbered groups is at the lower right of the layer, with the remaining 2 through 6, at the left. The scales and dimensions of the bars are given by the expression
