Dongguan combination of soft and hard production

With high wiring density, light weight, thin thickness, good bending characteristics! Combined with hard and soft board (reechas Softandhardcombinationplate) - with birth and development of PCB, FPC plate led to the soft hard couple, this new product. Therefore, the combination of soft and hard board, is the FPC flexible circuit board and hard circuit board, after pressing and other processes, according to the relevant process requirements combined together, formed with 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 FPC flexible circuit board. 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 through the effective treatment, so as to reduce the module operating temperature, prolong the service life, improve reliability; Medical FPC7, 3M adhesive paper - mainly used for 0.4mm and above thickness OF FR4 and FPC paste, and FPC and customer product assembly fixed; The use of FPC auxiliary materials, ultimately according to the customer's use environment and functional requirements to determine the product FPC flexible circuit board: 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 e is no difference between circuit board and circuit board, essentially the same. The classification of FPC circuit board is classified according to its medium and structure, which is sorted as follows: 1, single layer soft board structure FPC circuit board this structure of the flexible board is the most simple structure of the flexible board. 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. Technical aspects: According to different materials and manufacturing process, fiberboard can be divided into three types: double-sided copper foil fiberboard, perforated copper foil fiberboard and single-sided copper foil fiberboard. 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 panels 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.
