Shenzhen laser head treatment flexible circuit board manufacturers wholesale

Advantages of flexible circuit board aluminum substrate PCB: A loose.  Heat is significantly better than standard FR-4 structures.  B. The dielectric used is usually 5 to 10 times the thermal conductivity of conventional epoxy glass and 1/10 of the thickness.  The heat transfer index is more efficient than traditional rigid PCBS.  D. You may use copper weights lower than those shown on IPC recommended charts.  Audio equipment: input amplifier, output amplifier, balance amplifier, audio amplifier, preamplifier, power amplifier, etc.  2. Power supply equipment: switching voltage regulator 'DC/AC converter SW voltage regulator, etc.  Laser head treatment flexible circuit board what is aluminum substrate: Aluminum substrate is a metal base copper clad plate with good heat dissipation function, generally single panel is composed of three layers of structure, respectively is the circuit layer (copper foil).  Insulating layer and metal base laser head therapy flexible circuit board  

The working principle of the flexible circuit board is to use the plate insulation material to separate the copper foil conductive layer on the surface, so that the current flows along the pre-designed route in various components, such as doing work.  Amplification. Attenuation. Modulation.  Demodulation coding and other functions.  At home and abroad on the future printed board manufacturing technology development trend of the discussion is basically the same, that is, to high density.  High precision. Fine aperture.  Fine wire. Fine pitch laser head treatment flexible circuit board  

On a basic PCB, the parts are concentrated on one side and the wires are concentrated on the other.  Because the wires only appear on one side, the PCB is called a single panel.  Multilayer plate. The layers have wires and must be properly connected by a circuit between the two layers. The bridge between the circuits is called the guide hole (VIA).  The basic circuit board design process can be divided into the following four steps: common in LED lighting products.  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.  The IP  

(2) Observe the electronic components in the circuit have no traces of high temperature, and the electrolytic capacitor has no leakage phenomenon, if so, it should be replaced.  2. Annual maintenance :(1) clean up the dust on the circuit board.  (2) Spot check on the capacity of electrolytic capacitor in the circuit board. If it is found that the capacity of electrolytic capacitor is lower than 20% of the nominal capacity, it should be replaced. Generally, the life of electrolytic capacitor should be replaced for about ten years to ensure the working performance of the circuit board.  High reliability. Multi-layer.  High speed transmission and light weight.  Thin direction development, in production at the same time to improve productivity, reduce costs, reduce pollution, adapt to the variety, small batch production direction development.  The technical development level of printed circuit is generally represented by the line width, aperture, and thickness/aperture ratio on the printed board.  

1. Audio equipment: input.  Output amplifier. Balanced amplifier.  Audio amplifier. Preamplifier.  Power amplifier, etc.  2. Power supply: switch regulator.  DC/AC converter.  A patch device is generally placed on the aluminum substrate of laser head therapy wiring plate such as SW regulator. The tube and output rectifier tube conduct heat out through the substrate, and the thermal resistance is very low, which can achieve high reliability.  The transformer adopts plane patch structure, but also through the substrate heat dissipation, the temperature rise is lower than the conventional, the same specification transformer adopts aluminum substrate structure can get larger output power.  Due to excellent thermal conductivity aluminum plate, difficult in small amount of manual welding, solder cooling too fast, easy problems existing a simple and practical method, will be a common electric iron used ironing temperature adjustment function is), turn it over, ironing, oriented fixed well, the temperature to 150 ℃ or so, put the aluminum plate on top of the iron, heating time,  Then stick the components and welding in accordance with the conventional method, the temperature of the iron is suitable for easy welding of the device, too high may be damaged when the device, or even aluminum plate copper peel, the temperature is too low, the welding effect is not good, to be flexible.  3. Communication electronic equipment: high frequency amplifiers, filter appliances, transmitting circuits.  4. Office automation equipment: motor drivers, etc.  5. Car: Electronic regulator.  Igniter. Power controller, etc.  6. Computer: CPU board.  Floppy disk drives, power supply units, etc.
