Description

Technical Field

[0001] The utility model relates to the field of ceramic substrate cleaning, in particular to an automatic copper-clad ceramic substrate cleaning machine. Background Art

[0002] Copper-clad ceramics, also known as copper-clad ceramic substrates, are an electronic basic material made by sintering copper foil directly on the ceramic surface using DCB (Direct Copper Bond) technology. With the development of electronic technology, the integration of chips continues to increase, the width of circuit wiring becomes finer, and the power dissipation per unit area becomes larger and larger, which will inevitably increase the heat and easily cause the failure of the device. Direct copper-clad ceramic substrates have become important electronic packaging materials due to their good thermal and electrical conductivity, especially in power modules and integrated power electronic modules. The existing cleaning methods for substrates are still partially manual, which is too inefficient and will waste a lot of human resources. Some are cleaned by cleaning machines. Most of the existing cleaning machines use ultrasonic cleaning. This method also requires the copper-clad ceramic substrate to be placed in the ultrasonic machine for a certain period of time before it can be cleaned.
