Dongguan smart earphone FPC how to choose

Now the high thermal conductivity is usually ceramic, copper, etc., but because considering the cost of doubt, most of the aluminum substrate on the market now, the corresponding thermal conductivity of aluminum substrate is the parameter we care about, the higher the thermal conductivity is one of the symbols of the better function. Aluminum substrate is a common metal base copper-clad aluminum substrate, which has good thermal conductivity, electrical insulation and machining function. The thermal conductivity of aluminum substrate usually has 1.0, 1.5, 2.0, the specific situation depends on the need for goods. Intelligent headset FPCPCB board and aluminum substrate are designed in accordance with the requirements of PCB board. Currently, aluminum PCB board in the market is generally single-sided aluminum substrate. PCB board is a large type, and aluminum substrate is only a type of PCB board, which is aluminum base board, because of its good thermal conductivity. Generally used in LED industry smart headset FPC

Circuit board: PRINTED board on an insulating substrate, formed by a predetermined design to connect wires from point to point, but without printed elements. Circuit board: A printed board on an insulating substrate formed to a predetermined design to connect wires from point to point and to print components. Generally speaking, the circuit board is already equipped with various components of the board, and the circuit board is not equipped with components, just a good design of the substrate. There is no difference between a circuit board and a circuit board, essentially the same. PCB board is generally copper substrate, which can also be divided into single panel and double panel. There are obvious differences in the materials used between the two. The main material of aluminum substrate is aluminum plate, while the main material of PCB board is copper. Aluminum substrate because of its SPECIAL PP material. Heat dissipation is better. The price is also more expensive. What is PCB,PCB (PrintedCircuitBoard), Chinese name known as PrintedCircuitBoard, referred to as printed board, is one of the important components of the electronic industry. Almost every kind of electronic equipment, from electronic watches and calculators to computers, communication electronic equipment and military weapon systems, as long as there are integrated circuits and other electronic components, for the electrical interconnection between them, they need to use printed board smart headset FPC

2. In the production of aluminum substrate process between the process operators must be light, in order to avoid the surface is wiped. 3. In the production process, operators should avoid using their hands to touch the effective area of the aluminum substrate as far as possible, tin spraying and later process holding plate only allowed to hold the plate edge, is prohibited to touch the plate directly with their fingers. 4 aluminum base plate is a special plate, its production should cause each area each process attaches great importance to, section chief, foreman personally to the quality, to ensure the smooth production of plate in each process. In larger electronic product research, the most fundamental success factor is the design, documentation, and manufacture of the printed board for the product. The design and manufacturing quality of PCB directly affect the quality and cost of the whole product, and even lead to the success or failure of commercial competition.

The role of fpcPCB: after electronic equipment adopts printed board, due to the consistency of similar printed board, the error of manual wiring is avoided, and electronic components can be automatically inserted or attached, automatic soldering, automatic detection, to ensure the quality of electronic equipment, improve labor productivity, reduce cost. And it is convenient to maintain the design of FPC (1) circuit schematic diagram of smart earphone -- the design of circuit schematic diagram is mainly to draw schematic diagram by using ProtelDXP schematic editor. (2) generate reports - network statement that shows the links of all components in the circuit principle and relationship of the report, it is connected to circuit schematic design and circuit board design of bridge and link, through the network statements circuit schematic diagram, can quickly find the components, the relation between which provide convenience for the back of the PCB design. 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.
