Shenzhen soft light belt FPC thickness

1. As the volume decreases, the assembly area of radiator and other hardware (including thermal interface materials) is reduced, the product volume is reduced, and the cost of hardware and assembly is reduced. 2. Good mechanical endurance, compared with some simple process to make ceramic circuit boards. Disadvantages of aluminum substrate :1, high cost: compared with other affordable goods, the price of aluminum substrate accounts for more than 30% of the product price is not in line with the standard. 2, at present, the mainstream can only do single panel, do double panel process is difficult: at present, the domestic single panel is more skilled, the process and technology of multi-layer board is more mature abroad, there are more people to understand. Soft lamp with FPC3, made of products in electrical strength and pressure is more prone to problems: this problem is mainly related to the material itself. 4, aluminum base in the pressure index of the plate will cause the impact of substandard; The pressure resistance of the whole lamp and aluminum substrate is not up to standard; Influence of circuit design and structure design on voltage resistance

And some aluminum substrates used in LED lights in the market actually can not withstand 800V. So aluminum substrate is not very good soft lamp with FPC5, thermal conductivity test method and test results do not match, there is a certain difference between the thermal conductivity of the dielectric layer and the thermal conductivity of the finished aluminum substrate. 6, aluminum base copper clad plate material specifications are not unified. CPCA industry standards, national standards, international standards and so on. 7, copper foil thickness is not up to standard, will lead to burning circuit, fried power supply and other phenomena. More and more PCB manufacturers, copycat defective spoiler, jerry-built, shoddy, shoddy replacement. Soft light with FPC disk: No matter the hard disk or floppy disk, all rely on FPC's high flexibility and 0.1mm thin thickness, complete the fast reading of data, whether PC or NOTEBOOK; Latest uses: harddiskdrive (HDD,harddiskdrive) mount circuit and packaging board components of the soft light belt FPC

3. Filling: used for copper coating of ground wire network, which can reduce impedance. 4. Electrical boundary: used to determine the size of the circuit board, all components on the circuit board must not exceed this boundary. Circuit board names are: circuit board, PCB board, aluminum substrate, hf board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printing (copper etching technology) circuit board and so on. The circuit board makes the circuit miniaturized and intuitive, which plays an important role in the batch production of fixed circuit and the optimization of electric appliance layout. Circuit boards may be called printed circuit boards or printed circuit boards, English name is (PrintedCircuitBoard) PCB, FPC PCB (FlexiblePrintedCircuitboard) [1] (FPC circuit board, also known as flexible PCB flexible circuit board is made of polyimide or polyester film as the backing material with a high reliability,Flexible printed circuit board. The future development of FPC, based on the broad market of FPC in China, large enterprises from Japan, the United States and Taiwan countries and regions have set up factories in China. By 2012, flexible boards, like rigid boards, had made great progress. However, if a new product according to the "start - development - climax - decline - elimination" of the law, FPC is in the area between the climax and decline, before there is no product can replace flexible plate, flexible plate to continue to occupy market share, it must be innovative, only innovation can let it out of this vicious circle.

The role of flexible lamp belt fpcPCB: electronic equipment using printed board, due to the consistency of similar printed board, so as to avoid the error of manual wiring, and electronic components can be automatically inserted or mounted, automatic soldering, automatic detection, to ensure the quality of electronic equipment, improve labor productivity, reduce the cost, And easy to repair the soft lamp with FPC (2) observe the electronic components in the circuit have no traces of high temperature, electrolytic capacitor has no swelling leakage phenomenon, if so, should be replaced. 2. Annual maintenance :(1) clean up the dust on the circuit board. (2) Spot check on the capacity of electrolytic capacitor in the circuit board. If it is found that the capacity of electrolytic capacitor is lower than 20% of the nominal capacity, it should be replaced. Generally, the life of electrolytic capacitor should be replaced for about ten years to ensure the working performance of the circuit board. Development of PCB: Printed board from single-layer development to double-sided, multi-layer and flexible, and still maintain their own development trend. Due to the continuous development of high precision, high density and high reliability, and constantly reduce the volume, reduce the cost, improve the performance, making the printed board in the future electronic equipment development project, still maintain a strong vitality.
