Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of MEMS micromirror packaging, and relates to a MEMS micromirror packaging workbench which can be lifted and lowered freely. Background Art
[0002] The disadvantages of MEMS micromirror packaging in terms of inconvenience in flexible lifting and adjustment are mainly reflected in its structural and material limitations. The packaging of MEMS micromirrors often requires precise alignment and fixation on a tiny scale, which easily leads to error accumulation during the packaging process and limits the flexibility of the micromirror lifting and adjustment.
[0003] The reason for these shortcomings is that the physical size of MEMS micromirrors is extremely small, and the precision requirements of the packaging process are extremely high. Conventional coping methods include adopting more sophisticated packaging technologies, such as bonding technology, using packaging materials with low expansion coefficients, etc., to reduce the impact of temperature and mechanical stress on the micromirrors. However, the disadvantages of these methods are that they often increase manufacturing costs and complexity, and have higher requirements for the manufacturing environment and equipment, which may lead to reduced production efficiency and lower yield rates. Therefore, there is an urgent need for a freely liftable MEMS micromirror packaging workbench to solve the above problems. Utility Model Content
