Ceramic copper clad laminate refers to manufacturing a circuit board (PCB) by attaching a layer of copper foil to the surface on a high thermal conductivity ceramic substrate. Its characteristic is that the ceramic-covered copper foil can provide better thermal stability and mechanical strength, so It can be used at high temperatures and pressures, making it an ideal material in high-end electronics such as satellites, aerospace electronics and power electronics.
In the process of making circuit boards from ceramic copper clad laminates, printing solder resist is an important step.Thick film screen printing technology is usually used to print solder mask ink or photosensitive solder mask on the surface of the circuit board.After printing, it needs to be heated and cured, and then a chemical corrosion solution is used to deeply etch the parts other than the printed layer to remove unnecessary copper and retain the copper foil required for the circuit, thereby forming a protective layer to prevent the circuit board from being damaged. Components and circuits are short-circuited and corroded, improving the reliability and stability of the circuit board.
Process flow
1. First clean the surface of the circuit board to ensure that the surface is smooth and free of impurities.
2. Use thick film screen printing technology to print the solder resist layer on the surface of the circuit board.
3. Perform baking shaping, UV curing, deep etching and other processes on the printed solder resist layer.
Technical advantages
At present, many solder mask printing methods use spraying. However, the uniformity and thickness control of the spraying need to be considered when spraying. It cannot quickly adapt to different printing requirements and achieve different printing sizes and thicknesses like thick film screen printing. shape to ensure printing quality and film thickness consistency.The fully automatic loading and unloading printing machine for ceramic copper clad laminates produced by Jianyu Screen Printing has a printing accuracy of up to ±0.01mm and is suitable for double-sided printing of ceramic copper clad laminates of different sizes. The printing unit adopts printing adaptive technology and can print according to its size, shape, The printing pressure is automatically adjusted when the thickness changes, which greatly increases the yield and maintains the consistency of the product film thickness.
Thick film screen printing technology is widely used in the printing field of the electronics industry and can be used for printing ceramic media, ceramic covering layers, insulation layers, and solder resist layers.Jianyu Screen Printing, as a technical enterprise that has focused on the research and development and production of thick film screen printing equipment for 13 years, develops and produces high-precision screen printing machines with the advantages of high printing accuracy and high film thickness consistency.It is trusted and highly recognized by many customers in the electronics industry.Moreover, the demand for automation in the industry is getting higher and higher. Jianyu Screen Printing supports non-standard customization and designs automatic lines and related process solutions for customers, which can meet customers' refined and diversified needs.
