FPC circuit board working principle: is the use of plate insulation material separated from the surface copper foil conductive layer, so that the current along the pre-designed route in a variety of components flow to complete such as work, amplification, attenuation, modulation, solution
Tuning, coding and other functions. On a basic PCB, the parts are concentrated on one side and the wires are concentrated on the other. The FPC is called a single panel because the lead appears on only one side. FPC multilayer
A plate, with multiple layers of wires, must have an appropriate electrical connection between the two layers. The bridge between the two circuits is called a guide hole (VIA). The basic circuit board design process can be divided into the following four steps:
V Automobile brake lamp FPC aluminum substrate is a kind of metal base copper clad plate with good heat dissipation function. Generally, FPC single panel is composed of three layers, which are respectively circuit layer (copper foil), insulation layer and metal base. Common in LED lighting
Product V Automotive brake lights. There are both sides of FPC, the white side is welded LED pin, and the other side presents aluminum color. Generally, heat conduction paste will be smeared and contacted with the heat conduction part. There are ceramic substrates and so on. Aluminum substrate
Advantages :1 more suitable for SMT process 2 in line with RoHs requirements 3 Effective treatment of heat dissipation, so as to reduce the module operating temperature, prolong the service life, improve reliability; V Automotive brake lamp FPC6, aluminum substrate pad and
7. The color of the aluminum base plate is yellow and cannot be received. 8. The line and pad are consistent with the engineering drawings and samples, the line wireless is large, the line thin damage and other phenomena, the pad has no ink, no damage
(1) the design of circuit schematic diagram - the design of circuit schematic diagram is mainly using ProtelDXP schematic editor to draw schematic diagram. (2) Generate network report -- network report
It is a report that shows the link relationship between circuit principle and various components. It is the bridge and link between circuit schematic design and circuit board design. Through the network report of circuit schematic diagram, components can be quickly found
So as to provide convenience for PCB design. A. Aluminum substrate technical requirements, the main technical requirements are: size requirements, including plate size and deviation, thickness and deviation, verticality and warpage; Appearance, including crack
Lines, scratches, burrs and lamination, aluminum oxide film and other requirements; Performance, including peel strength, surface resistivity, minimum breakdown voltage, dielectric constant, combustion and thermal resistance requirements.
The structure of FPC double soft plate: when the circuit line is too complex, single layer plate can not wire or need copper foil to ground shielding, you need to choose double plate or even multi-layer plate V car brake
There are three differences between FPC glass fiber board and ALUMINUM based PCB: a. In terms of price, the important components of LED daylight lamp are: circuit board,LED chip and drive power supply. Common circuit boards come in two types: aluminum substrates
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 processes, glass
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. Made of different materials and techniques
Fibreglass panels vary in price. LED fluorescent tubes and fiberglass do not dissipate heat as well as LED fluorescent tubes with aluminum-based panels. The most typical difference between multilayer FPC boards and single-layer FPC boards is the addition of the through-hole structure to
The layers of copper foil are joined together. General substrate + transparent adhesive + copper foil the first processing process is to make holes. First in the base material and copper foil drilling, after cleaning coated with a certain thickness of copper, through the hole is ready. After the production process
Almost the same as single FPC board.
