Description

Technical Field

[0001] This utility model relates to the field of IGBT manufacturing technology, and in particular to a tilting mechanism and a tooling for plasma cleaning of IGBT modules. Background Technology

[0002] Plasma, like solids, liquids, and gases, is a state of matter, also known as the fourth state of matter. Applying sufficient energy to a gas to ionize it creates plasma. The "active" components of plasma include ions, electrons, active functional groups, excited-state nuclides (metastable states), and photons. Plasma cleaners utilize the properties of these active components to treat sample surfaces, achieving purposes such as cleaning, modification, and photoresist ashing.

[0003] For example, in IGBT module packaging, plasma cleaners are typically used to clean the surface of the IGBT module. In a vacuum chamber, a radio frequency power supply generates high-energy, disordered plasma under certain pressure. This plasma bombards the surface of the product being cleaned, achieving the cleaning purpose. However, plasma cleaning processes usually involve placing the product directly into the plasma cleaner, making it difficult to maintain consistent cleaning results. Utility Model Content
