Foshan soft and hard combined production matters needing attention

The soft and hard combination board has the characteristics of high wiring density, light weight, thin thickness and good bending! Combined with hard and soft board (reechas Softandhardcombinationplate) - flexible PCB FPC, the birth and development of the PCB plate led to the soft hard couple, the new product. Therefore, the combination of soft and hard board, is the flexible CIRCUIT board FPC and hard circuit board, after pressing and other processes, according to the relevant process requirements combined together, the formation of a flexible circuit board FPC characteristics and PCB characteristics of the circuit board.

Soft and hard bonded plate is a metal base copper clad plate with good heat dissipation function. Generally, a single panel is composed of three layers, which are respectively circuit layer (copper foil), insulation layer and metal base layer. Common in LED lighting products flexible circuit board FPC. There are positive and negative sides, the white side is welded LED pin, the other side is aluminum color, generally daub heat conduction paste and heat conduction part contact. There are ceramic substrates and so on.

Advantages of aluminum substrate :1, more suitable for SMT process; 2. Meet RoHs requirements; 3. The heat dissipation is effectively dealt with, so as to reduce the operating temperature of the module, prolong the service life and improve the reliability; Medical flexible CIRCUIT board FPC 7.3m adhesive paper - mainly used for FR4 with thickness of 0.4mm and above to paste flexible circuit board FPC, and flexible circuit board FPC and customer products assembly fixed; The use of flexible CIRCUIT board FPC auxiliary material, ultimately according to the customer's use environment and functional requirements to determine the product flexible circuit board FPC: on the insulating substrate, according to the predetermined design form from point to point to connect the wire, but no printed components of the printed board. 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. The classification of FPC of flexible circuit board is classified according to its medium and structure. It is sorted as follows: 1. The flexible board of FPC of single layer soft board structure is the most simple flexible board of structure. This is usually the base material + transparent adhesive + copper foil is a set of bought raw materials, of course, protective film + transparent adhesive is another kind of bought raw materials.

Function of soft and hard combination board: electronic equipment adopts 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 cost, There are three differences between the glass fiber board and the aluminum base board PCB: A. In terms of price, the important components of LED fluorescent tubes are: circuit board,LED chip and drive power supply. Common circuit boards come in two types: aluminum and fiberglass. Comparing the price of fiberglass with that of aluminum, fiberglass will be much cheaper, but the performance of aluminum will be better than fiberglass. B. Technology: According to different materials and manufacturing process, fiberglass can be divided into three types: double-sided copper foil fiberglass, perforated copper foil fiberglass and single-sided copper foil fiberglass. Of course, the price of fiberglass panels made of different materials will vary. Fiberglass panels are made of different materials and technologies at different prices. LED fluorescent tubes and fiberglass do not dissipate heat as well as LED fluorescent tubes with aluminum-based panels. 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.
