At present, most of the QFN lead frames purchased by domestic QFN packaging and testing companies are from abroad. There are few domestic supporting facilities and a low degree of automation. The yield rate of QFN lead frames is not high. There is an urgent need for supporting lead frame factories in China. Recently, after years of technology accumulation and painstaking research, Shenzhen Ogilvy Technology has joined forces with LG and Samsung technical teams, which are the most advanced in the QFN lead frame manufacturing technology and QFN packaging plastic packaging technology industries, and invested a lot of money and manpower to successfully design and manufacture Fully automatic roll-to-sheet high-density QFN lead frame etching equipment and selective plating equipment with a wafer output width of 400mm. It has filled the domestic gap, and many of its technical parameters are leading the world. It has once again assisted the upgrading of China's semiconductor manufacturing industry, promoted industry progress with core technologies, and led the rapid development of global semiconductors. Has the following characteristics:
1. The manufacturing processes of unwinding, developing, etching, film stripping, drying, and collecting of QFN and IC integrated circuit lead frame roll materials after exposure can be integrated into one set of equipment. This QFN etching equipment has a high degree of automation. The yield rate is greatly improved and the number of processes is reduced.
2. The rewinding device is designed using the most advanced flexible manufacturing concept in the world, and can switch between roll rewinding and sheet rewinding according to the customer's subsequent process requirements. Roll-type rewinding can separate large-width multi-row (2-6 rows) combined rolls online and collect them into independent rolls. The sheet rewinding system can cross-cut the roll material into pieces online and rewind the sheets automatically. Making the entire process more efficient, faster and more adaptable.
3. The high-precision fully automatic liquid medicine adding system adopts the latest sensor chemical analysis technology and refined electronically controlled metering and supply system to achieve precise quantitative control.
4. The unique spray pipeline and swing mechanism design uses high-power American Penguin pumps and Japanese IWAKI pumps to make the chemical liquid spray more fully and make the water washing more thorough.
