Flexible CIRCUIT board 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.  Because the wires appear on only one side, the flexible circuit board for brake lights is called a single panel.  Flexible PCB 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 flexible CIRCUIT board aluminum substrate is a kind of metal base copper-clad plate with good heat dissipation function. Generally, a single panel of flexible circuit board is composed of three layers, which are circuit layer (copper foil), insulation layer and metal base layer respectively.  Common in LED lighting  

Product V Automotive brake lights.  There are two sides of the flexible circuit board. The white side is welded LED pins, and the other side is aluminum. Generally, the thermal paste will be daubed and contacted with the thermal 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 flexible circuit board 6, 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.  

2. Double layer flexible circuit board structure flexible circuit board double layer soft board structure: when the circuit line is too complex, single layer board can not wire or need copper foil to ground shielding, you need to choose double layer or even multi-layer V car brake  

There are three differences between glass fiber board and aluminum based 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 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 a multilayer FPCB and a single-layer FPCB is the addition of a 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 a single layer flexible circuit board.
