Aluminium foil for electronic circuit is an electrical industrial use aluminum foil with grade of 1060 aluminum. 1060 aluminum foil has excellent corrosion resistance, thermal conductivity and good processing performance, so it has become an excellent raw material for aluminum foil gaskets, auto parts, capacitors, food packaging, electronic labels and other products.
Due to the high price of copper, aluminum has become an important substitute material for copper, and it has also become a trend in the manufacture of electronic circuit boards. With the expansion of the application of flexible printed circuit boards, the application of aluminium foil for electronic circuit has also become become possible. The production process and application of flexible electronic circuit boards using aluminum foil. The use of aluminum foil to replace copper foil not only reduces product quality, but also reduces costs, which is of great significance.
Use aluminium foil for electronic circuit to replace the existing copper foil to produce the circuit board base material. After the aluminum foil base material is finished, the circuit is made by the traditional circuit board production method, and then the circuit does not need to be connected to electricity and does not need to solder electronic components or LED lamp beads. A layer of solder mask or coating layer is applied on the top, and it leaks out where it needs to be welded, and then a layer of copper, nickel or silver is laid on the exposed welding position by chemical immersion copper, nickel or silver, to form the solder joints we need, and the surface of the aluminum foil in other positions does not change.
So that the aluminum foil can be used to replace the copper foil to produce the electronic circuit board, and it also solves the problem that the aluminum foil is not good for welding components, so that the amount of copper used on the electronic circuit board is greatly reduced, so the aluminum foil circuit board of the present invention is more environmentally friendly and has a lower production cost. In addition, the aluminum foil helps the heat dissipation of the electronic components on the circuit board, thereby contributing to the heat dissipation of electrical products to increase the service life of the product.
