The leading Rolled Copper Tape Foil, Lead Frame Copper Tape and Double Layer Flexible Copper Clad Laminate Supplier Expansion Hay:A03SXBT

At the new production base of SXBT Copper Material Technology Corporation, the Hay Think team happened to be from Mr. Tsukasa, a technical expert from Primetals Technologies in Japan.


"I am mainly in the rolled copper foil workshop, responsible for the technical guidance of the installation of the copper foil reversible finishing mill. The installation standard of this equipment is very strict, and each meter must be accurate to 0.05 mm. I need to follow up and guide the whole process, and it will take at least 3 months to complete the installation. " Mr. Tsukasa introduced.


There are currently only 5 manufacturers of precision rolled copper foil in China that have such equipment, which can produce precision rolled copper foil with a thickness of 6 microns.

Adjacent to the rolled copper foil workshop, the flexible copper clad laminate workshop covers an area of more than ten Mu. The upstream copper foil products are subjected to hot pressing, cooling, protective film separation and other processes, and the produced flexible copper clad laminates are used as finished products. For the preparation of flexible printed circuit boards, it is widely used in high-end mobile phones, computers, automotive electronics, aerospace and other fields, and has a broad international market.


SXBT's new production base covers an area of ​​296Mu with a total investment of 2.8 billion yuan.


The new production base will also produce new material products such as high-performance lead frame copper tape, oxygen-free copper copper tape, etc., which are positioned to replace imports and are widely used in 5G industry, new energy, intelligent manufacturing, graphene, large-scale integrated circuits, etc. field.


At present, workshops such as casting and copper strips are being constructed simultaneously. After completion, the production scale will reach 50,000 tons of high-performance rolled copper strips, 10,000 tons of high-precision rolled copper foils, and 2 million square meters of double-layer flexible copper clad laminates. "There are 105 sets of process equipment in the project, and 84 sets of international first-class equipment have been introduced. The main technological processes such as product thickness, plate shape and rolling speed can be completed with one click, with a high degree of automation and excellent products. The overall installed capacity is in the leading position in the world. , China's first-class."


It is worth mentioning that 6-high reversing finishing mills and 20-high reversing finishing mills from Germany will be installed here worth more than 60 million yuan. "In this workshop, 260mm-thick copper ingots are firstly hot-rolled and rough-rolled into 5mm-thick copper strips, which are then made to a thickness of 35 microns to 100 microns using these two German equipment, which can be used for integrated circuit leads. Frames, communication cables, RF cables, electronic components, etc.”
